⇱ glasp: A Go-based, Zero-dependency CLI for Google Apps Script (clasp Alternative) - DEV Community

If you use clasp for local Google Apps Script (GAS) development, you might have faced challenges with Node.js runtime overhead or slow deployment speeds.

glasp is a Go-based CLI tool designed to address these issues, offering high performance and a simplified developer experience.

What is glasp?

glasp is a CLI for managing Google Apps Script projects. By leveraging Go, it provides a standalone binary that eliminates the need for Node.js while maintaining high compatibility with the official clasp tool.

Key Features

  • Zero Dependencies: Runs as a single binary. No Node.js or npm install required.
  • clasp Compatibility: Works with existing .clasp.json and appsscript.json files. Commands like login, push, and pull follow the same syntax.
  • High Performance: Concurrent processing allows for significantly faster file scanning and uploading, especially in large projects.
  • GitHub Actions Optimized: A dedicated Action is available, allowing for deployment without setting up a Node.js environment.

Installation (Local)

For macOS and Linux, you can install glasp using the following script:

curl -sL https://takihito.github.io/glasp/install.sh | bash

Deployment via GitHub Actions

glasp is provided as a GitHub Action, so you can call it directly in your workflow. This eliminates the "Setup Node.js" step and reduces CI execution time.

name: Deploy to Google Apps Script
on:
 push:
 branches: [main]

jobs:
 deploy:
 runs-on: ubuntu-latest
 steps:
 - uses: actions/checkout@v4

 - name: Deploy with glasp
 uses: takihito/glasp@v0.2.8
 with:
 version: 'v0.2.8'
 auth: '${{secrets.CLASPRC_JSON}}'

Implementation Note:

  • Register the contents of your local ~/.clasprc.json as a GitHub Secret named CLASPRC_JSON.
  • Since it runs as a Docker container action, the environment setup is minimal and fast.

💡 Conclusion

glasp is a practical alternative for developers who want to decouple their GAS workflow from Node.js or optimize their CI/CD pipelines for speed.

If you are looking for a lightweight and faster way to manage your scripts while keeping your existing clasp configurations, glasp is a strong candidate.
