PL Conferences

A web application that tracks programming language conferences and workshops.

Adding Conferences

You can add conference information in two ways:

Via the web form

Visit the website and click "Submit Event" to use the form interface.

Via YAML files

1. Navigate to the appropriate year directory under packages/data/yaml/ (e.g., packages/data/yaml/2026/).
2. Create or edit a YAML file named after the conference abbreviation (e.g., icfp.yaml).
3. Use the following structure:

name: Full Conference Name
abbreviation: CONF
type: conference # or workshop, symposium
location: City, Country
date:
  start: 2026-01-15
  end: 2026-01-20
url: https://conference-website.com
importantDateUrl: https://conference-website.com/dates
importantDates:
  abstract: 2025-09-01
  paper: 2025-09-15
  # Optional dates:
  conditional-acceptance: 2025-10-10
  rebuttal: 2025-10-15
  notification: 2025-11-01
  camera-ready: 2025-12-01
  revisions: 2025-10-19

Conferences with multiple submission rounds use a rounds: array instead of flat importantDates — see existing files for examples. Dates can be set to TBD if not yet announced. The lastUpdated field is automatically managed from git history.

Data Updates

Conference data is checked daily by an automated process that:

1. Fetches the latest information from conference websites
2. Compares with existing data
3. Sends email notifications to me (cjohnson19) about any changes

Changes are reviewed manually, and I hope to update the pages quickly.

Development

This project is a pnpm monorepo. All packages live under packages/:

• packages/web/ — Next.js 16 frontend (static export to packages/web/out/)
• packages/core/ — Shared Zod schemas, date utilities, iCal generation
• packages/data/ — Conference YAML source and the generator that produces generated/events.{ts,json}
• packages/functions/ — AWS Lambda functions (form submission, drift detection)
• packages/cdk/ — AWS CDK infrastructure

Prerequisites

• Node.js 22+
• pnpm 11+

Running locally

pnpm install
pnpm run dev

The development server starts at http://localhost:3000. pnpm run dev regenerates event data from YAML first, then runs the Next.js dev server.

Available scripts

Script	Description
pnpm run dev	Generate events, then start Next.js dev server
pnpm run build	Generate events, then build the static site to packages/web/out/
pnpm run build:lambdas	Generate events, then bundle Lambda functions
pnpm run build:all	Generate once, then build both the site and Lambdas
pnpm run generate	Regenerate packages/data/generated/events.ts from YAML
pnpm run typecheck	Run tsc --noEmit across all packages
pnpm run lint	Run Biome (lint + format check) across the repo
pnpm run format	Apply Biome formatting fixes in place
pnpm run test	Run vitest (schema, AOE, countdown, and Puppeteer e2e tests)
pnpm run deploy	Deploy via scripts/deploy.ts <notification-email>

Code quality

• Biome handles linting and formatting for JS/TS/JSON/CSS; Prettier handles YAML/Markdown/HTML.
• Pre-commit runs lint-staged (auto-fixes staged files via Biome + Prettier) plus a full typecheck and lint.
