Replace strings in files while bundling them.
npm install --save-dev rollup-plugin-replace
Generally, you need to ensure that rollup-plugin-replace goes before other things (like rollup-plugin-commonjs) in your plugins array, so that those plugins can apply any optimisations such as dead code removal.
// rollup.config.js import replace from 'rollup-plugin-replace'; export default { // ... plugins: [ replace({ ENVIRONMENT: JSON.stringify('production') }) ] };
{ // a minimatch pattern, or array of patterns, of files that // should be processed by this plugin (if omitted, all files // are included by default)... include: 'config.js', // ...and those that shouldn't, if `include` is otherwise // too permissive exclude: 'node_modules/**', // To replace every occurrence of `<@foo@>` instead of every // occurrence of `foo`, supply delimiters delimiters: ['<@', '@>'], // All other options are treated as `string: replacement` // replacers... VERSION: '1.0.0', ENVIRONMENT: JSON.stringify('development'), // or `string: (id) => replacement` functions... __dirname: (id) => `'${path.dirname(id)}'`, // ...unless you want to be careful about separating // values from other options, in which case you can: values: { VERSION: '1.0.0', ENVIRONMENT: JSON.stringify('development') } }
By default, values will only match if they are surrounded by word boundaries — i.e. with options like this...
{ changed: 'replaced'; }
...and code like this...
console.log('changed'); console.log('unchanged');
...the result will be this:
console.log('replaced'); console.log('unchanged');
If that's not what you want, specify empty strings as delimiters:
{ changed: 'replaced', delimiters: ['', ''] }
