Grunt plugin for rollup - next-generation ES6 module bundler
npm install grunt-rollup> Grunt plugin for rollup - next-generation ES6 module bundler
>=0.4.0 and node >=8.6.0.If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
``shell`
npm install grunt-rollup --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
`js`
grunt.loadNpmTasks('grunt-rollup');
to the data object passed into grunt.initConfig().`js
grunt.initConfig({
rollup: {
options: {
// Task-specific options go here.
},
your_target: {
// Target-specific file lists and/or options go here.
},
},
});
`$3
Supports all the options from rollup's JavaScript API.
$3
A value of
true for sourceMap will output the map to a file with the same name as the JavaScript with .map appended. A value of inline for sourceMap will inline the sourcemap into the source file.$3
`js
grunt.initConfig({
rollup: {
options: {},
files: {
'dest/bundle.js': 'src/entry.js',
},
},
});
`$3
`js
var babel = require('@rollup/plugin-babel').default;grunt.initConfig({
rollup: {
options: {
plugins: [
babel({
exclude: './node_modules/**'
})
]
},
files: {
'dest/bundle.js': 'src/entry.js',
},
},
});
`#### Plugin getter
Some plugins are stateful and this doesn't play nice with multiple bundles.
For example the
rollup-plugin-babel plugin keeps a track of used babel helpers, and passing the configured plugin only once will cause the helpers to leak from one bundle to another.
To prevent that, pass a function that returns an array of plugins, like this:`js
var babel = require('rollup-plugin-babel');grunt.initConfig({
rollup: {
options: {
plugins: function() {
return [
babel({
exclude: './node_modules/**'
})
];
}
},
files: {
'dest/bundle.js': 'src/entry.js',
'dest/bundle2.js': 'src/entry2.js',
},
},
});
``This way the plugin will be refreshed for each bundle.
