Typescript Module w/ Definitions (TGRStack)

Development and Production Ready |⸰| VSCode Extensions

About

Expose all the knobs |⸰| As lean as a racehorse can get |⸰| Fork and keep as an upstream, then create your own modules

This starter kit is a launching point for ts/js module development (not React). Running the build script compiles the typescript code into a distribution that is ready to be published to a registry like NPM, and can easily be consumed by other TS modules. This module is part of a collection of uniformly built starter-kits designed for large-scale application development with TypeScript, GraphQL, and React. Find these, articles, and examplse at www.TGRStack.com. Skip to the bottom for links to a series of tutorials that walkthrough the creation of this module.

Commands - READ THIS

* nps                   # Executes the module, watching for rebuilds.
* nps help              # Displays all available commands
* nps commit            # Creates a commit, don't use `git commit -m ...`
* nps build             # Builds the module
* nps lint              # Lint checks the module
* nps test              # Test checks the module

Features

Core

• 🚀 ES2018+ support syntax that is stage-3 or later in the TC39 process.
• 🎛 Preconfigured to support development and optimized production builds
• 🎶 typescript incremental returns reducing development bugs

Style

• 🚦 tslint configured for strict, consistent, code style
• 🚦 ts-prettier for some of that code-consistancy that's missing from tslint
• 🚦 SonarTS Static code analyzer detects bugs and suspicious patterns

Tests

• 🎭 jest as the test framework.
• 🎭 ts-jest configured to test TS files, uses tsconfig.jest.json, and skip babel.
• 🎭 enzyme makes it easier to assert, manipulate, and traverse components.

Build (w/ Webpack)

• 📦 All source is bundled using Webpack v4
• 🌟 webpack for dev, prod, common
• 🚦 ts-loader for compiling typescript
• 🚦 webpack-graphql-loader for separating gql from ts files
• 💦 babel-loader for additional polyfills (browser support)
• 😎 HappyPack for ts-loader
• 🤖 code chunking for better production performance
• 🤖 Vendor.js for better developer experience
• 🤖 Vendor DLL for better performance
• 🎄 Tree-shaking
• 👻 DotEnv w/ friendly features docs: DotEnv
• ⛷ Module Aliasing docs: Module Aliasing
• ✨ terser-webpack-plugin instead of uglifyJS

Utils

• 🎮 nps npm scripts w/o a bloated package.json and limits of json docs: NPS.
• 🙌 commitizen to help us generate beautifully formatted and consistent commit messages.
• 😹 cz-emoji is a plugin for commitizen that adds emoji to the commit template.
• 🏆 standard-version is a replacement for npm version with automatic CHANGELOG generation
• ✅ commitlint validates commit messages to follow commitizen patterns

Getting started

To use the starter-kit to build your own ts-module run these commands:

git clone https://github.com/Falieson/2018-typescript-module.git my-project
cd my-project
rm -rf .git && git init
git commit -m "INIT'd w/ Falieson's 2018-typescript-module@SHA4985"
npm install
nps test
nps

Open package.json and reset following fields:

- name
- version ( It is recommended to start from 1.0.0 )
- description
- repository.url
- author
- license ( use whatever you want )

Now go make some changes to src/index.ts to see the tooling in action.

Docs

docs-dotenv

Webpack is configured to use a DotEnv plugin and uses DotEnv files in specific ways.

1. Everything in .env.example is considered a required .env field (compiler complains)
2. .env.development will be used if .env is missing
3. In production just use .env, this is ignored by git (as it should be!)

docs-module-aliases

Module aliases are defined in 2 places because of an issue w/ tsconfig-paths-webpack-plugin

• Aliasing for typescript, ts-node, ts-jest, the IDE are defined in tsconfig.json as expected.
• Since the webpack plugin isn't working, aliases are duplicated in ./webpack/config.js.

Any changes to one requires a change to the other!

docs-nps

node-package-scripts removes the limitation of package.json enabling Javascript and //comments.

To change scripts modify /scripts/ and use nps <command> instead of npm run <command>. The entry point for nps is ./package-scripts.js which routes to scripts/index.js which routes to the friendlier scripts/__index.js.

FAQ

Where are all the files in my IDE?

You must be using vscode! I have configured vscode workspace settings to hide everything from the filebrowser that you're unlikely to touch in day-to-day development.

Many files are still accessible through search (ctrl+p), such as the ./vscode/settings.json file where you can comment/uncomment my decisions and make everything your own.

P.S. you may like the tgrstack snippets extension since its formatted following the linting preferneces here.
