## API
|
|
|
|
### fromObject(obj)
|
|
|
|
Returns source map converter from given object.
|
|
|
|
### fromJSON(json)
|
|
|
|
Returns source map converter from given json string.
|
|
|
|
### fromBase64(base64)
|
|
|
|
Returns source map converter from given base64 encoded json string.
|
|
|
|
### fromComment(comment)
|
|
|
|
Returns source map converter from given base64 encoded json string prefixed with `//# sourceMappingURL=...`.
|
|
|
|
### fromMapFileComment(comment, mapFileDir)
|
|
|
|
Returns source map converter from given `filename` by parsing `//# sourceMappingURL=filename`.
|
|
|
|
`filename` must point to a file that is found inside the `mapFileDir`. Most tools store this file right next to the
|
|
generated file, i.e. the one containing the source map.
|
|
|
|
### fromSource(source)
|
|
|
|
Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was found.
|
|
|
|
### fromMapFileSource(source, mapFileDir)
|
|
|
|
Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was
|
|
found.
|
|
|
|
The sourcemap will be read from the map file found by parsing `# sourceMappingURL=file` comment. For more info see
|
|
fromMapFileComment.
|
|
|
|
### toObject()
|
|
|
|
Returns a copy of the underlying source map.
|
|
|
|
### toJSON([space])
|
|
|
|
Converts source map to json string. If `space` is given (optional), this will be passed to
|
|
[JSON.stringify](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify) when the
|
|
JSON string is generated.
|
|
|
|
### toBase64()
|
|
|
|
Converts source map to base64 encoded json string.
|
|
|
|
### toComment([options])
|
|
|
|
Converts source map to an inline comment that can be appended to the source-file.
|
|
|
|
By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would
|
|
normally see in a JS source file.
|
|
|
|
When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.
|
|
|
|
### addProperty(key, value)
|
|
|
|
Adds given property to the source map. Throws an error if property already exists.
|
|
|
|
### setProperty(key, value)
|
|
|
|
Sets given property to the source map. If property doesn't exist it is added, otherwise its value is updated.
|
|
|
|
### getProperty(key)
|
|
|
|
Gets given property of the source map.
|
|
|
|
### removeComments(src)
|
|
|
|
Returns `src` with all source map comments removed
|
|
|
|
### removeMapFileComments(src)
|
|
|
|
Returns `src` with all source map comments pointing to map files removed.
|
|
|
|
### commentRegex
|
|
|
|
Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments.
|
|
|
|
### mapFileCommentRegex
|
|
|
|
Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments pointing to map files.
|
|
|
|
### generateMapFileComment(file, [options])
|
|
|
|
Returns a comment that links to an external source map via `file`.
|
|
|
|
By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would normally see in a JS source file.
|
|
|
|
When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.
