Package Exports

source-list-map

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (source-list-map) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
