jeselvmo v2.1.1

Jeselvmo

A starter project that makes creating a TypeScript library extremely easy.

Usage

git clone https://github.com/kecoyo/jeselvmo.git YOURFOLDERNAME
cd YOURFOLDERNAME

# Run npm install and write your library name when asked. That's all!
npm install

Start coding! package.json and entry files are already set up for you, so don't worry about linking to your main file, typings, etc. Just keep those files with the same name.

Features

• Zero-setup. After running npm install things will setup for you :wink:
• RollupJS for multiple optimized bundles following the standard convention and Tree-shaking
• Tests, coverage and interactive watch mode using Jest
• Prettier and TSLint for code formatting and consistency
• Docs automatic generation and deployment to gh-pages, using TypeDoc
• Automatic types (*.d.ts) file generation
• Travis integration and Coveralls report
• (Optional) Automatic releases and changelog, using Semantic release, Commitizen, Conventional changelog and Husky (for the git hooks)

Importing library

You can import the generated bundle to use the whole library generated by this starter:

import jeselvmo from 'jeselvmo';

Additionally, you can import the transpiled modules from es/ in case you have a modular library:

import something from 'jeselvmo/es/something';

NPM scripts

• npm t: Run test suite
• npm start: Run npm run build in watch mode
• npm run test:watch: Run test suite in interactive watch mode
• npm run test:prod: Run linting and generate coverage
• npm run build: Generate bundles and typings, create docs
• npm run lint: Lints code

Excluding peerDependencies

On library development, one might want to set some peer dependencies, and thus remove those from the final bundle. You can see in Rollup docs how to do that.

Good news: the setup is here for you, you must only include the dependency name in external property within rollup.config.js. For example, if you want to exclude lodash, just write there external: ['lodash'].

Setup steps

Follow the console instructions to install semantic release and run it (answer NO to "Do you want a .travis.yml file with semantic-release setup?").

Note: make sure you've setup repository.url in your package.json file

npm install -g semantic-release-cli
semantic-release-cli setup
# IMPORTANT!! Answer NO to "Do you want a `.travis.yml` file with semantic-release setup?" question. It is already prepared for you :P

From now on, you'll need to use npm run commit, which is a convenient way to create conventional commits.

Automatic releases are possible thanks to semantic release, which publishes your code automatically on github and npm, plus generates automatically a changelog. This setup is highly influenced by Kent C. Dodds course on egghead.io

FAQ

Array.prototype.from, Promise, Map... is undefined?

TypeScript or Babel only provides down-emits on syntactical features (class, let, async/await...), but not on functional features (Array.prototype.find, Set, Promise...), . For that, you need Polyfills, such as core-js or babel-polyfill (which extends core-js).

For a library, core-js plays very nicely, since you can import just the polyfills you need:

import "core-js/fn/array/find"
import "core-js/fn/string/includes"
import "core-js/fn/promise"
...
