@jridgewell/source-map

Packages @jridgewell/trace-mapping and @jridgewell/gen-mapping into the familiar source-map API

This isn't the full API, but it's the core functionality. This wraps @jridgewell/trace-mapping and @jridgewell/gen-mapping implementations.

Installation

npm install @jridgewell/source-map

Usage

TODO

SourceMapConsumer

import { SourceMapConsumer } from '@jridgewell/source-map';
const smc = new SourceMapConsumer({

  names: ['foo'],
  sources: ['input.js'],
  mappings: 'AAAAA',
});

SourceMapConsumer.prototype.originalPositionFor(generatedPosition)

const smc = new SourceMapConsumer(map);
smc.originalPositionFor({ line: 1, column: 0 });

SourceMapGenerator

import { SourceMapGenerator } from '@jridgewell/source-map';
const smg = new SourceMapGenerator({
  file: 'output.js',
  sourceRoot: 'https://example.com/',
});

SourceMapGenerator.prototype.addMapping(mapping)

const smg = new SourceMapGenerator();
smg.addMapping({
  generated: { line: 1, column: 0 },
  source: 'input.js',
  original: { line: 1, column: 0 },
  name: 'foo',
});

SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)

const smg = new SourceMapGenerator();
smg.setSourceContent('input.js', 'foobar');

SourceMapGenerator.prototype.toJSON()

const smg = new SourceMapGenerator();
smg.toJSON(); // { version: 3, names: [], sources: [], mappings: '' }

SourceMapGenerator.prototype.toDecodedMap()

const smg = new SourceMapGenerator();
smg.toDecodedMap(); // { version: 3, names: [], sources: [], mappings: [] }
