# inline-source-map [](http://travis-ci.org/thlorenz/inline-source-map)
|
||
|
|
|
||
|
|
Adds source mappings and base64 encodes them, so they can be inlined in your generated file.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var generator = require('inline-source-map');
|
||
|
|
|
||
|
|
var gen = generator()
|
||
|
|
.addMappings('foo.js', [{ original: { line: 2, column: 3 } , generated: { line: 5, column: 10 } }], { line: 5 })
|
||
|
|
.addGeneratedMappings('bar.js', 'var a = 2;\nconsole.log(a)', { line: 23, column: 22 });
|
||
|
|
|
||
|
|
console.log('base64 mapping:', gen.base64Encode());
|
||
|
|
console.log('inline mapping url:', gen.inlineMappingUrl());
|
||
|
|
```
|
||
|
|
|
||
|

### addSourceContent(sourceFile, sourceContent)
|
||
|

```
|

/**

### base64Encode()
|

```

```
|
||
|
|
|
||
|
|
If source contents were added, this will be included in the encoded mappings.

### inlineMappingUrl()
|

|
|
|
||
