GitEvents Fetch


A Node.js library for fetching events and talks from GitEvents-based GitHub repositories using GitHub's GraphQL API. GitEvents uses GitHub Issues as a data source for managing community events and talk submissions.

Installation

``bash
npm install gitevents-fetch
`

Quick Start

`javascript
import { upcomingEvents } from 'gitevents-fetch'

// Fetch upcoming events from a repository
const events = await upcomingEvents('organization', 'repository')

console.log(events)
// [
// {
// title: 'Community Meetup - December 2025',
// number: 123,
// url: 'https://github.com/org/repo/issues/123',
// body: '...',
// date: Date('2025-12-01T00:00:00.000Z'),
// facets: { date: { date: '2025-12-01' }, ... },
// talks: [
// {
// title: 'Talk Title',
// author: { login: 'speaker', name: 'Speaker Name', ... },
// ...
// }
// ],
// reactions: ['THUMBS_UP', 'HEART']
// }
// ]
`

Authentication

GitEvents Fetch supports two authentication methods:

$3

1. Create a GitHub Personal Access Token with repo scope
2. Set the environment variable:

`bash
export GH_PAT="your_personal_access_token"
`

$3

1. Create a GitHub App
2. Generate and download a private key
3. Convert the private key to PKCS8 format:

`bash
openssl pkcs8 -topk8 -inform PEM -outform PEM -nocrypt \
-in github-app-private-key.pem -out private-key-pkcs8.key
`

4. Convert to base64 for environment variable storage:

`javascript
import { readFileSync } from 'fs'

const privateKey = readFileSync('private-key-pkcs8.key', 'utf8')
const base64Key = Buffer.from(privateKey).toString('base64')
console.log(base64Key)
`

5. Set the environment variables:

`bash
export GH_APP_ID="your_app_id"
export GH_PRIVATE_KEY="base64_encoded_private_key"
export GH_APP_INSTALLATION_ID="your_installation_id"
`

$3

| Variable | Required | Description |
| ------------------------------ | -------- | ------------------------------------------------------------------------- |
| GH_PAT | No\* | GitHub Personal Access Token |
| GH_APP_ID | No\* | GitHub App ID |
| GH_PRIVATE_KEY | No\* | Base64-encoded GitHub App private key (PKCS8 format) |
| GH_APP_INSTALLATION_ID | No\* | GitHub App installation ID |
| DEFAULT_APPROVED_EVENT_LABEL | No | Label filter for approved events (default: Approved :white_check_mark:) |

\*Either PAT or all GitHub App credentials are required. If both are provided, PAT takes precedence.

$3

Talks stored as issues in a dedicated repository can be fetched using the existing event functions:

`javascript
import { upcomingEvents, event } from 'gitevents-fetch'

// Fetch all talks (using different label if needed)
const talks = await upcomingEvents('myorg', 'talks-repo')

// Fetch specific talk by issue number
const talk = await event('myorg', 'talks-repo', 42)
`

Configure a custom label in your environment if talks use a different label:

`bash
export DEFAULT_APPROVED_EVENT_LABEL="Approved Talk"
`

$3

`typescript
{
title: string // Event title
number: number // GitHub issue number
url: string // GitHub issue URL

Error Handling

All API methods include comprehensive error handling and production-ready safety features:

$3

All functions validate required parameters before making API calls:

`javascript
import { upcomingEvents } from 'gitevents-fetch'

try {
const events = await upcomingEvents('myorg', 'events')
console.log(events)
} catch (error) {
if (error.message.includes('Missing required parameters')) {
console.error('Invalid parameters provided')
} else if (error.message.includes('Failed to fetch')) {
console.error('API error:', error.message)
}
}
`

$3

The library handles missing or null data gracefully:

- Missing reactions: Returns empty array instead of crashing
- Missing subIssues: Returns empty talks array
- Missing author: Returns null instead of undefined
- Missing date: Returns null instead of throwing errors

$3

Clear error messages for missing credentials:

`javascript
// Missing credentials error
Error: Missing GitHub App credentials. Set GH_APP_ID, GH_PRIVATE_KEY,
and GH_APP_INSTALLATION_ID environment variables, or provide
GH_PAT for token authentication.

// Invalid key format error
Error: Failed to create GitHub App authentication: Invalid key format.
Ensure GH_PRIVATE_KEY is base64-encoded.
`

Production-Ready Features

This library has been thoroughly tested and optimized for production use:

$3

- ✅ Null-safe: All GraphQL response fields safely handled with optional chaining
- ✅ Input validation: Required parameters validated before API calls
- ✅ Error handling: All async operations wrapped in try/catch with descriptive errors
- ✅ Edge cases: Handles missing dates, authors, reactions, and sub-issues gracefully

$3

- ✅ Optimized queries: GraphQL queries request only necessary fields
- ✅ Efficient sorting: Single-pass sorting with O(n log n) complexity
- ✅ Minimal dependencies: Only essential packages included

$3

- ✅ 32 comprehensive tests: Unit, integration, and real API tests
- ✅ 100% pass rate: All tests verified with live GitHub data
- ✅ CI/CD ready: Tests skip gracefully without credentials

$3

- ✅ ESLint: Zero warnings or errors
- ✅ Prettier: Consistent formatting enforced
- ✅ Conventional commits: Automated changelog generation
- ✅ Type hints: JSDoc-style documentation

Using with Vite/SSR

If you're using this package in a Vite project with Server-Side Rendering (SSR), you need to configure Vite to properly bundle the GraphQL files:

$3

`bash
npm install -D vite-plugin-graphql-loader
`

$3

Add the GraphQL loader plugin and include this package in ssr.noExternal:

`javascript
// vite.config.js
import { defineConfig } from 'vite'
import graphqlLoader from 'vite-plugin-graphql-loader'

export default defineConfig({
plugins: [graphqlLoader()],
ssr: {
noExternal: ['gitevents-fetch']
}
})
`

Why this is needed:

- The library imports .gql files using Vite's ?raw suffix for efficient bundling
- vite-plugin-graphql-loader enables Vite to process .gql files as modules
- Adding to ssr.noExternal ensures the package is bundled during SSR instead of being treated as an external dependency, allowing proper resolution of the GraphQL imports

Development

$3

- Node.js 20 or higher
- npm or yarn

$3

1. Clone the repository:

`bash
git clone https://github.com/gitevents/fetch.git
cd fetch
`

2. Install dependencies:

`bash
npm install
`

3. Set up environment variables (see Authentication)

$3

`bash
npm run lint # Run ESLint
npm test # Run tests
npm run build # Lint and test
npm run format # Format code with Prettier
`

$3

`bash


Run all tests

npm test

Run specific test file

node --test test/events.test.js

Run tests with coverage (using c8 or similar)

npx c8 npm test
`

All tests use mocked GraphQL responses and don't require actual GitHub credentials.

Integration Testing: The test suite includes a real API integration test that automatically runs when credentials are available in .env. It's skipped in CI/CD environments without credentials to prevent build failures.

`javascript
// Automatically skipped without credentials
test('upcomingEvents - real API call', {
skip: !process.env.GH_PAT && !process.env.GH_PRIVATE_KEY
}, async () => { ... })
`
