API

Example

var SourceListMap = require("source-list-map").SourceListMap; // Create a new map var map = new SourceListMap(); // Add generated code that is map line to line to some soure map.add("Generated\ncode1\n", "source-code.js", "Orginal\nsource"); // Add generated code that isn't mapped map.add("Generated\ncode2\n"); // Get SourceMap and generated source map.toStringWithSourceMap({ file: "generated-code.js" }); // { // source: 'Generated\ncode1\nGenerated\ncode2\n', // map: { // version: 3, // file: 'generated-code.js', // sources: [ 'source-code.js' ], // sourcesContent: [ 'Orginal\nsource' ], // mappings: 'AAAA;AACA;;;' // } // } // Convert existing SourceMap into SourceListMap // (Only the first mapping per line is preserved) var fromStringWithSourceMap = require("source-list-map").fromStringWithSourceMap; var map = fromStringWithSourceMap("Generated\ncode", { version: 3, ... });

new SourceListMap()

SourceListMap.prototype.add

SourceListMap.prototype.add(generatedCode: string) SourceListMap.prototype.add(generatedCode: string, source: string, originalSource: string) SourceListMap.prototype.add(sourceListMap: SourceListMap)

Append some stuff.

SourceListMap.prototype.prepend

SourceListMap.prototype.prepend(generatedCode: string) SourceListMap.prototype.prepend(generatedCode: string, source: string, originalSource: string) SourceListMap.prototype.prepend(sourceListMap: SourceListMap)

Prepend some stuff.

SourceListMap.prototype.toString()

Get generated code.

SourceListMap.prototype.toStringWithSourceMap

SourceListMap.prototype.toStringWithSourceMap(options: object)

Get generated code and SourceMap. options can contains file property which defines the file property of the SourceMap.

SourceListMap.prototype.mapGeneratedCode

SourceListMap.prototype.mapGeneratedCode(fn: function) : SourceListMap

Applies fn to each generated code block (per line). The returned value is set as new generated code. Returns a new SourceListMap.

Removing and adding lines is supported. The SourceMap complexity will increase when doing this.
