The npm package @jridgewell/sourcemap-codec is designed to encode and decode the mappings property of a sourcemap. Sourcemaps are challenging to generate and manipulate because the mappings property links the generated code back to the original source. This linkage is encoded using a method called Variable-length quantity. Every segment in the mapping contains offsets rather than absolute indices, making it essential to understand the whole sourcemap to look at a segment. The @jridgewell/sourcemap-codec package simplifies this process.
To use @jridgewell/sourcemap-codec, you first have to install it via npm using the command npm install @jridgewell/sourcemap-codec. Once the package is installed, you can import the encode and decode functions from it in your JavaScript files. Below is an example of its usage:
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode(';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC');
var encoded = encode(decoded);
In the above code snippet, decode function is used to decode a string of encoded mappings and encode function is used to encode the resultant array back into a string.
The documentation for @jridgewell/sourcemap-codec is available in the readme file in its GitHub repository. There you will find detailed information on how to use it, as well as some benchmarks about its performance.
