opencode-antigravity-auth-updated

1.6.2 verified Sat Apr 25 auth: no javascript

Google Antigravity IDE OAuth auth plugin for Opencode, providing access to Gemini 3 Pro and Claude 4.6 using Google credentials. Current stable version is 1.6.2, released with fixes for proper-lockfile interop and Node.js 25 compatibility. The plugin is updated frequently with beta releases introducing new features like TUI v2 and opt-in Claude 1M beta head. Key differentiators: offers access to latest AI models via Google Antigravity IDE, includes account rotation and quota management, and ships TypeScript types.

Common errors

error ERR_REQUIRE_ESM ↓

cause Using require() on an ESM-only package after v1.6.1.

fix

Use import syntax or rename file to .mjs.

error TypeError: AntigravityAuthProvider is not a constructor ↓

cause AntigravityAuthProvider is a named export, not default, so default import returns undefined.

fix

Change import to: import { AntigravityAuthProvider } from 'opencode-antigravity-auth-updated'

error Cannot find module 'opencode-antigravity-auth-updated' ↓

cause Package not installed or cache is stale.

fix

Run 'npm install opencode-antigravity-auth-updated' and clear cache: rm -rf ~/.cache/opencode/node_modules

Warnings

breaking Node.js 20+ is required; older versions will throw a runtime error due to ESM imports and missing APIs. ↓

fix Upgrade Node.js to version 20 or later (e.g., via nvm).

breaking ESM-only since v1.6.1; CommonJS require() will fail with 'ERR_REQUIRE_ESM'. ↓

fix Switch to ESM (type: 'module' in package.json or .mjs extension) and use import syntax.

deprecated The 'quotaCheck' option is deprecated since v1.6.0; use 'interactiveQuotaCheck' instead. ↓

fix Replace quotaCheck with interactiveQuotaCheck in configuration.

gotcha GitHub Actions auto-triggers may cause multiple builds; cache clearing is needed after version updates. ↓

fix Clear cache with 'rm -rf ~/.cache/opencode/node_modules ~/.cache/opencode/bun.lock' after updating.

gotcha TypeScript types are shipped but require typescript^5 as peer dependency; missing peer dep may cause type errors. ↓

fix Install typescript@^5 as a devDependency.

Install

npm install opencode-antigravity-auth-updated

yarn add opencode-antigravity-auth-updated

pnpm add opencode-antigravity-auth-updated

Imports

default

wrong

const AntigravityAuth = require('opencode-antigravity-auth-updated')

correct

import AntigravityAuth from 'opencode-antigravity-auth-updated'

CommonJS require is not supported; this package is ESM-only since v1.6.1.

AntigravityAuthProvider

wrong

import AntigravityAuthProvider from 'opencode-antigravity-auth-updated'

correct

import { AntigravityAuthProvider } from 'opencode-antigravity-auth-updated'

AntigravityAuthProvider is a named export, not default. Ensure correct importing to avoid undefined.

AntigravityAuthConfig

wrong

import { AntigravityAuthConfig } from 'opencode-antigravity-auth-updated'

correct

import type { AntigravityAuthConfig } from 'opencode-antigravity-auth-updated'

AntigravityAuthConfig is a TypeScript type and should be imported using 'import type' to avoid runtime errors.

Quickstart

Shows how to import and instantiate the AntigravityAuth class with OAuth credentials, then trigger authentication.

import AntigravityAuth from 'opencode-antigravity-auth-updated';

const auth = new AntigravityAuth({
  clientId: process.env.GOOGLE_CLIENT_ID ?? '',
  clientSecret: process.env.GOOGLE_CLIENT_SECRET ?? '',
  redirectUri: 'http://localhost:3000/callback'
});

async function main() {
  try {
    const token = await auth.authenticate();
    console.log('Authentication successful, token:', token);
  } catch (error) {
    console.error('Authentication failed:', error);
  }
}

main();
