• Modules: Hybrid ESM/CJS
• Types: TypeScript
• Tests: Vitest
• Linting: ESLint
• Formatting: dprint
• Publishing: Dripip
• Continuous Integration: GitHub Actions
• Dependency Management: Renovate
• Community: Issue Templates

Quick Start

Make sure you have corepack enabled:

$ corepack enable

Used as a GitHub Template Repo

The following will get you a ready to go new repository on GitHub based on this one.

1. Run:

   gh repo create foobar --template jasonkuhrt/template-typescript-lib --clone --public && \
   cd foobar && \
   pnpm install && \
   pnpm bootstrap

2. Setup a repo secret called NPM_TOKEN containing an npm token for CI package publishing.

Used With Manual Git Setup

The following will get you a ready to go new repository on GitHub based on this one.

1. Run:

   gh repo clone jasonkuhrt/template-typescript-lib <directory> && \
   cd <directory> && \
   pnpm install && \
   pnpm bootstrap

2. Setup a repo secret called NPM_TOKEN containing an npm token for CI package publishing.

TypeScript for Type Safety & Productivity

1. Optimal settings for type safety via @tsconfig/node18 and @tsconfig/strictest

2. .tsbuildinfo cache setup, output discretely into node_modules/.cache

3. Base tsconfig.json shared across tests and src.

4. Optimal output setup for your users

   1. declaration so your users can power their intellisense with your packages typings.
   2. declarationMap enabled to make your published source code be navigated to when your users use "go to definition".
   3. package.json typeVersions used to emit only one set of declaration files shared by both CJS and ESM builds.
   4. sourceMap enabled to allow your users' tools to base off the source for e.g. stack traces instead of the less informative derived built JS.
   5. Publish src with build files so that jump-to-definition tools work optimally for users.

5. tsx for running TypeScript scripts/modules.

ESLint For Linting

1. TypeScript integration
2. TS type-checker powered eslint checks enabled
3. Setup as a CI check for PRs
4. Always display as warning to keep IDE error feedback for TypeScript (CI enforces warnings).
5. Auto-fixable import sorting

Vitest for Testing

Just Works :)

Dripip for Releasing

Simple succinct friendly low-barrier issue templates

1. Emojis ✈️
2. Feature / bug / docs / something-else
3. Config to display discussions link right in new issue type listing UI

dprint for code formatting

1. Setup as a CI check for PRs
2. VSCode extension in recommended extensions list so that when collaborators open the project they'll get prompted to install it if they haven't already.
3. npm script

npm scripts for development lifecycle

1. clean to remove cache and build files
2. build that runs clean beforehand
3. prepublishOnly that runs build beforehand
4. format to run dprint over whole codebase
5. lint to run eslint over whole codebase

CI with GitHub Actions

1. Separate trunk and pull-request (PR) workflows.
2. Dependency install cache enabled.
3. On PR:
   1. Formatting Check
   2. Lint Check
   3. Type Check
   4. Tests across matrix of mac/linux/windows for Node 14/16
4. On trunk:
   1. Tests across matrix of mac/linux/windows for Node 14/16
   2. Automated canary release

Renovate configuration

1. JSON Schema setup for optimal intellisense
2. Group all non-major devDependency updates into single PR (which "chore" conventional commit type)
3. Group all major devDependency updates into single PR (with "chore" conventional commit type)
4. Group all non-major dependency updates into single PR (with "deps" conventional commit type)
5. Each major dependency update in own PR (with "deps" conventional commit type)

PnPM for package management

1. Using Corepack. This means the PnPM specified in package.json will be used. And note this is a PnPM binary shipped with Node now. In a future version of Node you will not need to even opt-in into Corepack. Make sure you've done corepack enable at least once.

CJS+ESM Hybrid package build

An actually working hybrid CJS/ESM build.

VSCode Settings

1. Optimize project search by recursively (ready for monorepo) ignoring build/*, snapshots, lock files, and more.
2. On-Save actions for optimal editing experience (e.g. ESLint auto-fix to organize imports automatically)
3. List of VSCode extensions that users who open the project will be prompted to install if they don't already.
4. Enable typescript.enablePromptUseWorkspaceTsdk so that oneself and collaborators will get prompted to use the workspace version of TypeScript instead of the one in the editor.

Readme Table of Contents

1. Using markdown-toc
