API

• extract(string) extracts an inline source map from the given string. The returned object has the js without source maps and a map with source maps.
• consumer(map) returns a source map consumer for the given map.
• line(consumer, line[, offset]) maps the given line to the original source using a consumer. If offset is given, it is substracted from the line number.
• stream(consumer[, offset]) returns a through2 stream that replaces URLs in stack traces with the original source location using a consumer. If offset is given, it is substracted from the line number.
• stream(map[, offset]) returns a through2 stream that replaces URLs in stack traces with the original source location using a source map. If offset is given, it is substracted from the line number.
