Advanced tools
Develop Apps Script projects locally using clasp (Command Line Apps Script Projects).
To get started, try out the codelab!
🗺️ 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:
tests/slides.gstests/sheets.gstests/
slides.jssheets.js🔷 Write Apps Script in TypeScript: Write your Apps Script projects using TypeScript features:
First download clasp:
sudo npm i @google/clasp -g
Then enable Apps Script API: https://script.google.com/home/usersettings
(If that fails, run this:)
sudo npm i -g grpc @google/clasp --unsafe-perm

clasp logoutCreates a new script project.
scriptTitle: An optional project title.scriptParentId: An optional 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.rootDir: Local directory in which clasp will store your project files.

"projectId": "project-id-xxxxxxxxxxxxxxxxxxx"
}
Now you can run clasp logs for this project.
.claspignore)Like .gitignore, .claspignore allows you to ignore files that you do not wish to not upload on clasp push. Steps:
.claspignore in your project's root directory.clasp push. Note: The .claspignore file is parsed with Anymatch, 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
.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/",
"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. 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.
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.
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
