What is sourcemap-codec?

The sourcemap-codec npm package is designed for encoding and decoding mappings between original and generated code as represented in a source map. It provides efficient operations for working with the VLQ (Variable-Length Quantity) encoding used in source maps, making it easier to manipulate and understand the relationships between source and transformed code.

What are sourcemap-codec's main functionalities?

Encoding source map mappings

This feature allows you to encode an array of source map mappings into a compact string using VLQ encoding. The example demonstrates encoding mappings for two lines of code.

const { encode } = require('sourcemap-codec');
const mappings = [
  [ [ 0, 0, 0, 0 ], [ 1, 0, 1, 17 ] ], // First line mappings
  [ [ 0, 0, 1, 0 ] ] // Second line mappings
];
const encodedMappings = encode(mappings);

Decoding source map mappings

This feature enables the decoding of a VLQ-encoded string representing source map mappings back into a more understandable array format. The example shows how to decode a string into mappings for two lines.

const { decode } = require('sourcemap-codec');
const encodedMappings = 'AAAA,CAAC;AACA';
const mappings = decode(encodedMappings);
