Learn how to create a new dataform web project and connect to your warehouse.

Creating a new project

This tutorial demonstrates the first few steps in configuring a new project.

Google BigQuery is used as the data warehouse in this example. 

## Log in or sign up

After opening [the app](https://app.dataform.co/).

![Sign up](/static/images/how_to_guides/dataform_101/1_sign_up.png)

If not signing in with GitHub, Google or Microsoft then you will need to verify your email address.

## Create new project

This will create a new, empty project.

## Next Steps

You've taken the first steps towards improving your data pipeline!

Some of the next features you could use next include:

- Automating repeated runs using [scheduling](../guides/scheduling).

- Checking validity of data using [assertions](../../guides/assertions) or [unit tests](../../guides/tests).

- [Documenting datasets](../../guides/documentation).


Start building out your dataform pipelines using SQLX files and managing dependencies.

Managing dependencies

This tutorial demonstrates how dependency trees are made within a project.

## Create a new file

Create a new file by clicking on the + button next to the `definitions` folder and create a new SQLX file named `onboarding_table`.
For now, ignore the other options; these are more advanced features which will be covered in later documentation.

![New file](/static/images/how_to_guides/publish_tables/new_file.png)

## Write a query

In the text editor, write a simple SQLX statement:

```js
config { 
  type: "view" 
}

select 
  1 as one,
  2 as two,
  3 as three
```

You will see the right sidebar update with `onboarding_table` which is the name of the dataset, a tag for the type - a `view` - as well as a validation message and two action buttons.

The `Preview results` button executes the query in your warehouse and returns the output at the bottom of the page. This can be useful during query development to check that the query returns expected output.

<img
src="/static/images/how_to_guides/publish_tables/compilation.png"
style="width: 100%"
/>

## Run the query

Clicking the `Run this action` button will open a dialog box with a few options for running your actions. Click `Run now` to continue.

Upon successful completion of the run, a new view named `dataform.onboarding_table` will be created in your warehouse.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-primary" markdown="1">
  By default, Dataform creates datasets and views under a schema named <code>dataform</code>. You
  can change this in the <code>dataform.json</code> in your
  <a href="../../guides/configuration">project configuration</a>.
</div>

![Run node](/static/images/how_to_guides/publish_tables/run_node.png)

## Create a table instead of a view

To create a table instead of a view, simply change your script's `config` block:

```js
config { 
  type: "table" 
}
```

You will see the tag on the right sidebar update from `view` to `table`.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-none" markdown="1">
  Dataform provides many other options for dataset creation. Learn about
  <a href="../../guides/datasets">publishing datasets</a> and
  <a href="../../guides/incremental-datasets">incremental datasets</a>.
</div>

<img
src="/static/images/how_to_guides/publish_tables/table_vs_view.png"
style="width: 100%"
/>

## Referencing other datasets

Dataform provides methods that enable you to easily reference another dataset in your project using the `ref()` function:

```js
select 
  * 
from 
  ${ref('my_table')}
```

This provides two advantages:

- You don’t have provide the full SQL dataset name.
- Any dataset that is referenced by a query will be automatically added to that query's dependencies. Dependency queries are always executed before dependent queries to ensure correctness.

## Create a new file

Create a new SQLX file named `onboarding_table2` and add the following content:

```js
config { 
  type: "view" 
}

select
  * 
from
  ${ref('onboarding_table')}
```

<img
src="/static/images/how_to_guides/publish_tables/ref_query.png"
style="width: 100%"
/>

You will see the right sidebar update with the name of the view, `onboarding_table2`. Clicking on `Compiled query` will display the fully qualified query to be run in your data warehouse.
The `${ref()}` function will be replaced with the actual name of the dataset in your data warehouse. Note that the dependency is also listed just above the compiled query.

_*Your compiled script will differ depending on your cloud data warehouse. This example uses Redshift.*_

<div className="bp3-callout bp3-icon-info-sign bp3-intent-warning" markdown="1">
  Referencing a dataset that hasn't yet been created in your data warehouse will cause validation
  errors. These validation errors are warning you that the dataset you are referencing doesn't exist
  (yet). However, since Dataform will run your project's scripts in dependency order, you can safely
  ignore these errors.
</div>

## View dependency tree

The overview page (linked at the top left of Dataform) gives you an overview of your project. The overview includes a visualization of the dependency tree of your project, containing the two datasets created by your scripts.

<img
src="/static/images/how_to_guides/publish_tables/dependencies.png"
style="width: 100%"
/>

In bigger projects containing dozens or hundreds of datasets with complicated interdependencies, the overview page can help you keep track of your project's overall structure.

Learn how to use version control in Dataform Web.

Version control

## Introduction

Dataform uses the Git version control system to maintain a record of each change made to project files and to manage file versions. Each Dataform project has an associated Git repository.

By default, Dataform will manage your project's Git repository for you. However, projects can be configured to use GitHub instead by clicking the `Migrate project to GitHub` button in Settings.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-primary" markdown="1">
  Version control is tightly integrated into Dataform Web and has consequences on how your data
  pipelines run. We strongly recommend understanding the following concepts before developing your
  datasets in Dataform.
</div>

## Branches

One of the main benefits of Git is that a developer can work in an isolated "branch" of the file repository without affecting the base files. Dataform has full support for Git branches.

From any non-`production` branch you can edit files (and run those edited scripts on your warehouse, if desired).

Once you are happy with your changes, you can commit them and push them to the `master` branch. If at any point you make changes that you don't want to commit, you can revert your branch to its last commit.

Note that the `production` branch is not directly editable and **all schedules run from the production branch**. This enables users to develop and test changes without affecting the project's data pipelines or affecting other users.

### Personal and shared branches

When you first use Dataform we will automatically create a personal development branch for you, `name_dev`. Only you can see this branch and commit to it.

It's also possible to create a shared branch, which everyone in the project can see and commit to. These can be useful if you're collaborating with someone on a project.

### Creating and deleting branches

To create a new branch, open the branch selection menu and click "New Branch". You will have the option to make it a shared branch.

To delete a branch, first open the branch. Then, from the version control settings, choose the `Delete branch` option.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-warning" markdown="1">
If you delete a branch, any changes which have not yet been pushed to `production` will be lost.
</div>

## How to use version control

Select the branch you would like to use to make your changes.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-warning" markdown="1" style="margin-bottom: 10px">
  We recommend that each team member uses their own separate development branch.
</div>

After making changes to files, you can commit them. You will be shown a list of the modified files, and asked to provide a commit message.

Once you are happy with your changes, you can `Push to master`. The changes will now be on `production` and used for future schedule runs.

## Reverting uncommitted changes

If you'd like to undo any changes you've made since your last commit, you can `Revert uncommitted changes` from the version control menu.

## Resolving merge conflicts

If other changes have been pushed to the `master` branch while you were making edits in your branch, you will need to pull those changes into your branch first by choosing `Pull from master`.

There may be conflicting edits that you will have to manually resolve. Files with conflicts are highlighted in the files list. Once you are comfortable with your edits, you can commit and push your changes to `master`.

Learn how to use Git access tokens for connecting to git providers.

Git access tokens

Git access tokens are important for Dataform projects linked to remote git providers, such as GitHub. They provide authentication for accessing and controlling the git project.

## User authentication

User access tokens are used to authenticate git access of Dataform projects during project manipulation.

Without a valid access token, users will be unable to do things such as create branches.

They must be configured to have both **read and write access** to your remote repository.

They can be added or removed on the **user settings page**.

## Scheduler authentication

Scheduler access tokens are used to authenticate git access of Dataform projects when running automated schedules.

Without a valid access token, the scheduler will not be able to read the contents of the project and perform the run.

They must have **read** access to your remote repository.

<div className="bp3-callout bp3-icon-info-sign bp3-intent-warning" markdown="1">
  GitHub doesn't support read-only access to the repo. You should use the <code>repo</code> <a target="_blank" rel="noopener" href="https://developer.github.com/apps/building-oauth-apps/understanding-scopes-for-oauth-apps">scope</a>
</div>

They can be updated on the **project settings page**, within the app.

For projects with only a few collaborators (e.g. 3), it's ok to use a user's personal access token to authenticate the scheduler, but for larger teams a **machine user** is recommended. If you have a DevOps team, ask them about whether a machine user already exists.

### Machine user

Machine users are generally regular user accounts, but used purely to run automated (or triggered) tasks.

If a user's personal access token is used and they leave the organization or their permission is revoked, then the scheduler will fail.

Because of this, **we recommend to have a global machine user on organization level, to make sure there is no disruption during scheduling**.

Check [this](https://developer.github.com/v3/guides/managing-deploy-keys/#machine-users) for further info on creating machine users.

Before creating a machine user on GitHub, please read their [TOCs](https://help.github.com/en/github/site-policy/github-terms-of-service#3-account-requirements).

## Creating git access tokens

How to create a git access token differs between remote git providers.

### GitHub

Learn how to schedule runs and view logs

Schedule runs

Learn about environments in Dataform web and how to configure them

Environments

## Introduction

By default, Dataform runs all of your project code from your project's `master` Git branch. Configuring environments allows you to control this behaviour, enabling you to run multiple different versions of your project code.

**An environment is effectively a wrapper around a version of your project code.** Once you have defined an environment, and added some schedules to that environment, Dataform runs all of those schedules using the environment's version of the project code.

A common use-case for environments is to run a staged release process. After testing code in a `staging` environment, the code is promoted to a stable `production` environment.

<callout intent="info">
  If you would like to use environments, please verify that the version of <code>@dataform/core</code> that your project uses is at least <code>1.4.9</code>.
</callout>

<br />

<callout intent="info">
  Environments are an advanced feature. To get the most out of them, the <b>use of an external Git provider is recommended</b>. This makes it easier to view specific commit SHAs, manage Git branches and tags, and control your release process.
</callout>

## Configuring environments

Environments are configured in your Dataform project's `environments.json` file.

An environment consists of:

- a name
- a Git reference at which the code should be run (one of: a branch name, tag name, or a commit SHA)
- (optionally) overridden values for the project's configuration (the settings in `dataform.json`)
- (optionally) some schedules

<callout intent="warning">
If an environment is configured using a tag or branch, that tag or branch must exist in the project's remote Git repository (e.g. GitHub, if the project is stored there). Note that <b>Dataform branches are not equivalent to remote Git branches</b>.
</callout>

A simple example of an `environments.json` file is:

```json
// environments.json
{
  "environments": [
    {
      "name": "staging",
      "gitRef": "67bed6bd4205ce97fa0284086ed70e5bc7f6dd75",
      "configOverride": {
        "defaultDatabase": "dataform_staging"
      },
      "schedules": [
        {
          "name": "run_everything_once_per_day",
          "cron": "0 10 * * *"
        }
      ]
    }
  ]
}
```

This `staging` environment runs the `run_everything_once_per_day` schedule at the `67bed6bd...` Git commit SHA. It also overrides the value of
`defaultDatabase` to isolate `staging` schedule runs from those in other environments.

Note that Dataform uses the `environments.json` file on your `master` branch to determine your project's environments. **Any changes to your environments must be pushed to `master` before Dataform will take note of those changes**.

### Code that depends on environment/schedule name

Dataform injects two special [variables](/guides/configuration#configure-custom-compilation-variables) when schedules are executed: `environmentName` and `scheduleName`. You can use these in your code by referencing `dataform.projectConfig.vars`. For example, to select 10% of data in a `staging` environment:

```js
// definitions/my_view.sqlx
config { type: "view" }

select
  *
from ${ref("data")}
${when(
  dataform.projectConfig.vars.environmentName === "staging",
  "where farm_fingerprint(id) % 10 = 0",
)}
```

## Example: manage a production release process using environments

More advanced Dataform projects typically have a tightly-controlled `production` environment. All changes to project code go into a `staging` environment which is intentionally kept separate from `production`. Once the code in `staging` has been verified to be sufficiently stable, that version of the code is then promoted to the `production` environment.

Note that a `staging` environment is typically not useful for code development. Usually during development you would simply run all code using the project's default settings (as defined in `dataform.json`). Thus, unless you want Dataform to run schedules in a `staging` environment, it may not be useful to define one.

A clean and simple way to separate staging and production data is to use a different database for each environment. However, this is only supported for BigQuery and Snowflake, so we recommend using per-environment schema suffixes for other warehouse types. The examples below show how to do both by overriding project configuration settings.

### Configuration via commit SHA

In the below example:

- the `production` environment is locked to a specific Git commit

- the `staging` environment runs the project's schedules at the latest version of the project's code (as exists on the `master` branch)

A nice property of this configuration is that any change to the `production` environment leaves an audit trail (by being recorded in your project's Git history).

```json
// environments.json
{
  "environments": [
    {
      "name": "production",
      "gitRef": "PRODUCTION_GIT_COMMIT_SHA_GOES_HERE",
      "configOverride": {
        "defaultDatabase": "dataform_production"
      },
      "schedules": [ ... ]
    },
    {
      "name": "staging",
      "gitRef": "master",
      "configOverride": {
        "defaultDatabase": "dataform_staging"
      },
      "schedules": [ ... ]
    }
  ]
}
```

To update the version of the project running in `production`, change the value of `commitSha`, and then push that change to your `master` branch. On GitHub, Git commit SHAs can be found by opening the project page and clicking 'commits'.

<callout>
  <p>A Git branch or tag can be specified instead of a commit SHA:</p>
  <p>
  <code>"gitRef": "GIT_BRANCH_OR_TAG_NAME_GOES_HERE"</code>
  </p>

<p>
However, we do not recommend using Git branches to manage a <code>production</code> environment:

  <ul>
    <li>Managing merges across Git branches can be tricky and occasionally produces confusing results</li>
    <li>Consequently, the audit trail of changes made to the environment can be harder to follow</li>
  </ul>
</p>
</callout>

### Per-environment schema suffixes

An alternative approach to separating production and staging data is to append a suffix to schemas in each environment. For example:

```json
// environments.json
{
  "environments": [
    {
      "name": "production",
      "gitRef": "PRODUCTION_GIT_COMMIT_SHA_GOES_HERE",
      "configOverride": {
        "schemaSuffix": "_production"
      },
      "schedules": [ ... ]
    },
    {
      "name": "staging",
      "gitRef": "master",
      "configOverride": {
        "schemaSuffix": "_staging"
      },
      "schedules": [ ... ]
    }
  ]
}
```

## Example: use separate databases for development and production data

Some teams may not be at the stage where they require a `staging` environment, but still would like to keep development and production data separated. This can be done using a `configOverride` in the `production` environment.

In the example below:

- any code deployed during development will use `defaultDatabase` from the `dataform.json` file
- schedules are defined in the `production` environment, and so use the `defaultDatabase` from that environment's `configOverride`
- the `production` environment specifies the `master` Git branch, so all of its schedules will run using the latest version of the code

```json
// dataform.json
{
  "warehouse": "bigquery",
  "defaultSchema": "dataform_data",
  "defaultDatabase": "analytics-development"
}
```

<br />

```json
// environments.json
{
  "environments": [
    {
      "name": "production",
      "gitRef": "master",
      "configOverride": { "defaultDatabase": "analytics-production" },
      "schedules": [ ... ]
    }
  ]
}
```

Note that the `defaultDatabase` setting is only supported for BigQuery and Snowflake. For other warehouses, we recommend overriding schema suffixes (as described above).

Learn about configuring slack notifications with Dataform web

Slack Notifications

## Introduction

Success and failure alerts for schedule runs can be configured as part of schedule set up. This guide explains how to set
up notifications to a [Slack](https://www.slack.com) channel.

## Create an Incoming WebHook url for your slack workspace

1. Open the [Incoming WebHook](https://dataformco.slack.com/apps/A0F7XDUAZ-incoming-webhooks?next_id=0) app.
2. Click "Add to Slack".
3. Choose the slack channel you would like alerts to be sent to
4. Click "Add Incoming WebHooks Integration".
5. On the next page you will see a "Webhook URL". You'll need this for the next step.

## Create a notification channel and link the webhook url

1. Open a development branch.
2. Navigate to the scheduling page using the left menu.
3. Open the "Notification Channels" tab.
4. Click "Add Channel". Give the channel a name, choose the "Slack" notification type, and copy in the "Webhook URL" from
   the previous step.
5. Click "Create Channel".

## Add the notification channel to a schedule

1. Open the "Schedules" tab on the schedules page.
2. Create a new schedule, or edit an existing schedule.
3. In the "Notifications" section of the schedule dialogue, click "Add new notification settings".
4. Select the channel you just created. Choose `success`, `failure` or both as "Events".


slack-notifications

## Introduction

Schedules can be used to run any selection of your datasets at a user-specified frequency. Running your code on a repeating schedule ensures output data is always kept up to date.

## Create a schedule

Schedules are created as part of an [environment](scheduling/environments).

1. Navigate to your `environments.json` file
2. Click `Create new schedule` on the environment in which the schedule should run (by default you will only have a single `production` environment)
3. Enter your schedule's settings
4. Commit your changes to `environments.json` and push these to `master`

## View past runs

You can find all current and historical scheduled runs in the _Run logs_ page, accessible using the left menu bar.

![Run logs](https://assets.dataform.co/docs/bigquery_billing.png)

## Scheduler access tokens

For projects using a remote git project (e.g. hosted on GitHub), a scheduler access token is required. [More info on configuring git access tokens](./git-access-tokens).

Learn how to use the REST API to control Dataform Web

Use the REST API

Web API Reference

reference

<br/>
<div class="bp3-callout bp3-icon-info-sign bp3-intent-warning">
  The Dataform Web API is currently in Beta, and breaking changes are likely to happen.
</div>

## Authorization

Calls to the Dataform Web API are authenticated using API tokens. These can be created from the Dataform project's settings page.

When calling the API, you can pass your API token in an `Authorization` header, using a bearer token format.

For example, with `curl` these headers can be provided as follows:

```bash
curl -H "Authorization: Bearer 5235783003799552|s+N8gAs72qbi90pFEv7yW/KBImTshRdBoVKjjFA7lD0=|1" https://api.dataform.co/v1/project/1234/run/5678
```

## Creating runs

Runs can be created by making a `POST` call to the `RunCreate` method.

For detailed documentation on supported parameters, see the [`RunCreate`](api/reference#RunCreate) reference documentation.

For example, to create a run for the project ID `1234` and to trigger a specific schedule name:

```bash
curl -H "Authorization: Bearer 5235783003799552|s+N8gAs72qbi90pFEv7yW/KBImTshRdBoVKjjFA7lD0=|1" -X POST -d '{ "scheduleName": "some_schedule" }' https://api.dataform.co/v1/project/1234/run
```

This will return a [RunGetResponse](api/reference#/definitions/v1RunCreateResponse), that includes the created run's ID:

```json
{
  "id": "1029591293203"
}
```

## Getting run information

After creating a run, the status of the run can be checked with the [`RunGet`](api/reference#RunGet) method.

This should be a `GET` request to the appropriate path, for example for project ID `1234` and a run ID `5678`:

```bash
curl -H "Authorization: Bearer 5235783003799552|s+N8gAs72qbi90pFEv7yW/KBImTshRdBoVKjjFA7lD0=|1" https://api.dataform.co/v1/project/1234/run/5678
```

This will return a [`RunGetResponse`](api/reference#/definitions/v1RunGetResponse) such as:

```json
{
  "id": "5678",
  "status": "RUNNING",
  "runLogUrl": "https://app.dataform.co/#/1234/run/5678"
}
```

## Triggering a Dataform schedule from a 3rd party orchestration tool

Using the REST API it's possible to trigger Dataform schedules from a third party orchestration tool, like Airflow or Luigi.

The following example, written in Python, shows how you can trigger a schedule, check its status every 10 seconds, and exit when the schedule finishes.

```python
import requests
import time
import json

base_url='https://api.dataform.co/v1/project/<PROJECT_ID>/run'
headers={'Authorization': 'Bearer <API_TOKEN>'}
run_create_request={"environmentName": "<ENVIRONMENT_NAME>", "scheduleName": "<SCHEDULE_NAME>"}

response = requests.post(base_url, data=json.dumps(run_create_request), headers=headers)

run_url = base_url + '/' + response.json()['id']

response = requests.get(run_url, headers=headers)

while response.json()['status'] == 'RUNNING':
    time.sleep(10)
    response = requests.get(run_url, headers=headers)
    print(response.json())
```
