Concatenate file contents with a custom separator and generate a source map
The concat-with-sourcemaps npm package allows you to concatenate multiple files and generate source maps for the concatenated output. This is particularly useful in build processes where you need to combine multiple JavaScript or CSS files into a single file while maintaining the ability to debug the original source files.
Concatenate files
This feature allows you to concatenate multiple files into a single file. The example code demonstrates how to concatenate two JavaScript files, 'file1.js' and 'file2.js', into a single file 'all.js'.
const Concat = require('concat-with-sourcemaps');
const concat = new Concat(true, 'all.js', '\n');
concat.add('file1.js', 'console.log("file1");\n');
concat.add('file2.js', 'console.log("file2");\n');
console.log(concat.content.toString());
console.log(concat.sourceMap);Generate source maps
This feature allows you to generate source maps for the concatenated output. The example code demonstrates how to add source maps for 'file1.js' and 'file2.js' with a specified source root.
const Concat = require('concat-with-sourcemaps');
const concat = new Concat(true, 'all.js', '\n');
concat.add('file1.js', 'console.log("file1");\n', { sourceRoot: 'src' });
concat.add('file2.js', 'console.log("file2");\n', { sourceRoot: 'src' });
console.log(concat.content.toString());
