Rollup plugin to build dependency files suitable for make
mangle: [Default:output.filewith existing extension replaced by.d] A function that will be passedoutput.fileand should return the file to write dependencies to.
Suppose a make rule builds dist/script/* from script/*. With an input of script/app.js, the plugin will write dependencies to dist/script/app.d by default. In the example below, dependencies will instead be written to dist/.dep/script/app.d:
import make from 'rollup-plugin-make';
import path from 'path';
export default {
...
plugins: [
...
make({
mangle: (file) => {
const outputStem = 'dist/';
const input = file.replace(outputStem, '');
const inputDep = `${input.substring(0, input.lastIndexOf('.'))}.d`;
return path.join(outputStem, '.dep', inputDep);
},
}),
],
};
