Clasp

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

To get started, try out the codelab!

You can also try clasp in Gitpod, a one-click online IDE for GitHub:

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

🔷 Write Apps Script in TypeScript: Write your Apps Script projects using TypeScript features:

Arrow functions
Optional structural typing
Classes
Type inference
Interfaces
And more…

➡️ Run Apps Script: Execute your Apps Script from the command line. Features:

Instant deployment.
Suggested functions Autocomplete (Fuzzy)
Easily add custom Google OAuth scopes
And more…

- V8 support take advantage of the performance boost of Chrome JavaScript engine:

Every ES2019 features (except ES modules)
Edit your appsscript.json manifest to choose between the Rhino and V8 engines
Typescript users should update their tsconfig.json with the "target": "ES2019" compiler option

Create

Creates a new script project. Prompts the user for the script type if not specified.

Options

--type [docs/sheets/slides/forms]: If specified, creates a new add-on attached to a Document, Spreadsheet, Presentation, or Form. If --parentId is specified, this value is ignored.
--title <title>: A project title.
--rootDir <dir>: Local directory in which clasp will store your project files. If not specified, clasp will default to the current directory.
--parentId <id>: A project parent Id.
- The Drive ID of a parent file that the created script project is bound to. This is usually the ID of a Google Doc, Google Sheet, Google Form, or Google Slides file. If not set, a standalone script project is created.

These options can be combined like so:

clasp create --title "My Script" --parentId "1D_Gxyv*****************************NXO7o" --rootDir ./dist

Clone

Clones the script project from script.google.com.

Options

scriptId | scriptURL: The script ID or script URL to clone.
--versionNumber <number>: The version of the script to clone.
--rootDir <dir>: Local directory in which clasp will store your project files. If not specified, clasp will default to the current directory.

Examples

clasp clone "15ImUCpyi1Jsd8yF8Z6wey_7cw793CymWTLxOqwMka3P1CzE5hQun6qiC"
clasp clone "https://script.google.com/d/15ImUCpyi1Jsd8yF8Z6wey_7cw793CymWTLxOqwMka3P1CzE5hQun6qiC/edit"

Push

Force writes all local files to script.google.com.

Warning: Google scripts APIs do not currently support atomic nor per file operations. Thus the push command always replaces the whole content of the online project with the files being pushed.

Ignores files:

That start with a .
That don't have an accepted file extension
That are ignored (filename matches a glob pattern in the .claspignore file)

Options

-f --force: Forcibly overwrites the remote manifest.
-w --watch: Watches local file changes. Pushes files every few seconds.

Examples

clasp push
clasp push -f
clasp push --watch

Status

Lists files that will be written to the server on push.

Ignores files:

That start with a .
That don't have an accepted file extension
That are ignored (filename matches a glob pattern in the ignore file)

Guides

Ignore File (`.claspignore`)

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

Create a file called .claspignore in your project's root directory.
Add patterns to be excluded from clasp push. Note: The .claspignore patterns are applied by multimatch, which is different from .gitignore, especially for directories. To ignore a directory, use syntax like **/node_modules/**.

A sample .claspignore ignoring everything except the manifest and build/main.js:

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

Note: The .claspignore patterns are applied relative from the rootDir.

If no .claspignore is specified, a default set of patterns is applied. This default set will only consider the appsscript.json manifest and any JavaScript, TypeScript and .html source files within the rootDir folder. Child folders other than .git and node_modules are processed.

# ignore all files…
**/**

# except the extensions…
!appsscript.json
!**/*.gs
!**/*.js
!**/*.ts
!**/*.html

# ignore even valid files if in…
.git/**
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. Example .clasp.json:

{
  "scriptId": "",
  "rootDir": "build/",
  "projectId": "project-id-xxxxxxxxxxxxxxxxxxx",
  "fileExtension": "ts",
  "filePushOrder": ["file1.ts", "file2.ts"]
}

The following configuration values can be used:

`scriptId` (required)

Specifies the id of the Google Script project that clasp will target.

Open script url.
File > Project properties > Script ID

`rootDir` (optional)

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

`projectId` (optional)

Specifies the id of the Google Cloud Platform project that clasp will target. You must associate Google Script project with Google Cloud Platform beforehand.

Run clasp open.
Click Resources > Cloud Platform project....
Specify the project ID project-id-xxxxxxxxxxxxxxxxxxx.

Even if you do not set this manually, clasp will ask this via a prompt to you at the required time.

`fileExtension` (optional)

Specifies the file extension for local script files in your Apps Script project.

`filePushOrder` (optional)

Specifies the files that should be pushed first, useful for scripts that rely on order of execution. All other files are pushed after this list of files.

Troubleshooting

NodeJS Version

The library requires NodeJS version >= 10.3.0.

You can check your version of NodeJS with this command.

node -v

You can use these commands to upgrade NodeJS if necessary (not on Windows):

npm install -g npm # Update npm and npx
npx n latest # use the n package to update node

Using a Proxy

Clasp supports proxies via the Google APIs Node Module. See "Using a Proxy" and this discussion for details on how to use the proxy. This requires using the environment variables HTTP_PROXY / HTTPS_PROXY.
