Babel-preset-travi NPM

babel-preset-travi

My shareable babel preset

Usage

Installation

$ npm install babel-preset-travi --save-dev

Via `.babelrc` for internal development purposes

This will target the current version of node and transpile my preferred upcoming features.

{
  "presets": ["travi"]
}

In React projects

This will target the current node version, but will also transpile React features

{
  "presets": [["travi", {"react": true}]]
}

Via Rollup

Prevent transpilation of module imports/exports so Rollup can optimize properly
Transpile to the lowest common denominator of your expected consumers' execution environments

In the rollup.config.js:

export default {
  ...
  plugins: [
    babel({
      babelrc: false,
      exclude: ['./node_modules/**'],
      presets: [['travi', {targets: {node: 8}, modules: false}]],
    }),
    ...
  ],
  ...
};

In projects that target both node and browsers

export default {
  ...
  plugins: [
    babel({
      babelrc: false,
      exclude: ['./node_modules/**'],
      presets: [['travi', {targets: {node: 8, browser: true}, modules: false}]],
    }),
    ...
  ],
  ...
};

In React projects

export default {
  ...
  plugins: [
    babel({
      babelrc: false,
      exclude: ['./node_modules/**'],
      presets: [['travi', {
        targets: {node: 8, browser: true},
        react: true,
        modules: false
      }]],
    }),
    ...
  ],
  ...
};
