clasp

Develop Apps Script projects locally using clasp (Command Line Apps Script Projects).

To get started, try out the codelab!

Features

🗺️ Develop Locally: clasp allows you to develop your Apps Script projects locally. That means you can check-in your code into source control, collaborate with other developers, and use your favorite tools to develop Apps Script.

🔢 Manage Deployment Versions: Create, update, and view your multiple deployments of your project.

📁 Structure Code: clasp automatically converts your flat project on script.google.com into folders. For example:

• On script.google.com:
  • tests/slides.gs
  • tests/sheets.gs
• locally:
  • tests/
    • slides.js
    • sheets.js

Install

First download clasp:

sudo npm i @google/clasp -g

Then enable Apps Script API: https://script.google.com/home/usersettings

Commands

clasp

• clasp login [--no-localhost]
• clasp logout
• clasp create [scriptTitle] [scriptParentId]
• clasp clone <scriptId>
• clasp pull
• clasp push
• clasp open [scriptId]
• clasp deployments
• clasp deploy [version] [description]
• clasp redeploy <deploymentId> <version> <description>
• clasp version [description]
• clasp versions
• clasp list
• clasp logs [--json] [--open]

How To...

Login/Logout

clasp login
clasp logout

Run clasp login --no-localhost to manually enter a code instead of running a local server.

Run clasp login --ownkey to save the .clasprc.json file to your current working directory.

Create a New Apps Script Project

Files in the current directory are added to the project. Optinally provide a script title or parent G Suite doc ID.

clasp create [scriptTitle] [scriptParentId]

Clone an Existing Project in the Current Directory

clasp clone <scriptId>

Push/Pull

clasp push # Updates Apps Script project with local files
clasp pull # Updates local files with Apps Script project

Update a Published Project / Deploy

To deploy a project:

1. Create an immutable version of the Apps Script project using clasp version
2. Deploy the version using clasp deploy [version]

clasp versions # List versions
clasp version [description] # Create a new version with a description

then deploy...

clasp deploy [version] [description]
clasp undeploy <deploymentId>
clasp deployments # List all deployment IDs

Open the Project on script.google.com

clasp open [scriptId]

Opens the clasp project on script.google.com. Provide a scriptId to open a different script.

List your App Scripts (In Development)

clasp list
My Project           (1_M8ExSD9KI33fiVYbIOv-Cze0gWAzPYnPoSFb41eisVUOtyne8IDUjJ3)
Testing SlidesApp    (Cze0gWAzPYnPoSFb41eisVUOtyne8IDUjJg-1_M8ExSD9KI33fiVYbIOv)
Send Email           (isVUOtyne8IDUjJg-1_M8ExSD9KI33fiVYbIOvCze0gWAzPYnPoSFb41e)
...

This shows your 50 most recent scripts.

See your Logs (In Development)

To use clasp logs, you need to enter your script's Google Cloud projectId into .clasp.json.

Get Project ID

1. Run clasp open.
2. Click Resources > Cloud Platform project...
3. Copy the project ID project-id-xxxxxxxxxxxxxxxxxxx into .clasp.json. It should look like this:

{
  "scriptId":"14Ht4FoesbNDhRbbTMI_IyM9uQ27EXIP_p2rK8xCOECg5s9XKpHp4fh3f",
  "projectId": "project-id-xxxxxxxxxxxxxxxxxxx"
}

Now you can run clasp logs for this project.

Run clasp logs

Use clasp logs to see recent log messages from StackDriver. For example:

clasp logs
ERROR Sat Apr 07 2018 10:58:31 GMT-0700 (PDT) myFunction      my log error
INFO  Sat Apr 07 2018 10:58:31 GMT-0700 (PDT) myFunction      info message

Other Options

• clasp logs --json: See the logs in JSON format.
• clasp logs --open: Open the StackDriver logs in your browser.

Ignore File (.claspignore)

Like .gitignore, .claspignore allows you to ignore files that you do not wish to not upload on clasp push. Steps:

1. Create a file called .claspignore in your project's root directory.
2. Add patterns as if it were a .gitignore, and they will be excluded from clasp push.

A sample .claspignore could look like:

**/**
!build/main.js
!appsscript.json

In this example, clasp ignores everything but the manifest and build/main.js.

Note: the .claspignore file is parsed with Anymatch, making it match files differently from a typical .gitignore, especially with directories. To ignore a directory, use syntax like **/node_modules/**.

Project Settings File (.clasp.json)

When running clone or create, a file named .clasp.json is created in the current directory to describe clasp's configuration for the current project. The following configuration values can be used in it:

scriptId (required)

Specifies the id of the Google Script project that clasp will target. It is the part located inbetween /d/ and /edit in your project's URL: https://script.google.com/d/<SCRIPT_ID>/edit.

rootDir (optional)

Specifies the local directory in which clasp will store your project files. If not specified, clasp will default to the current directory.

Troubleshooting

The library requires Node version >= 4.7.4. Use this script to check your version and upgrade Node if necessary:

node -v # Check Node version
sudo npm install n -g
sudo n latest

Develop

The Apps Script CLI uses TypeScript to provide autocompletion and linting when developing. Use an IDE like Visual Studio Code for TypeScript autocompletion.

Setup

Install tsc: npm install -g typescript

After Making a Change

sudo npm run build;
clasp <command>

Run Tests (experimental)

Change describe.skip(...) to describe(...) for relevant tests.

sudo npm run build;
npm run test

Publishing clasp to npm (admin)

1. Build index.js locally. .gitignore/.npmignore will hide js/ts files appropriately.
2. Bump versions, then publish with: npm publish --access public

Contributing

The main purpose of this tool is to enable local Apps Script development. If you have a core feature or use-case you'd like to see, find a GitHub issue or create a detailed proposal of the use-case. PRs are very welcome! See the issues (especially good first issue and help wanted).

How to Submit a Pull Request

1. Look over the test cases in tests/test.ts, try cases that the PR may affect.
2. Run tslint: npm run lint.
3. Submit a pull request after testing your feature to make sure it works.
