inline-sourcemap-concat

inline-sourcemap-concat

Concatenate sources and inlined sourcemaps into a new generated sourcemap. Only inline sourcemaps are processed - external sourcemap references are discarded.

methods

var SourceMapConcat = require('inline-sourcemap-concat')

var sm = SourceMapConcat.create(opts={})

Returns an instance of SourceMapConcat.SourceMap.

Optionally pass in:

• opts.baseDir - a string of the base directory from which to resolve the sourcemap sources.
• opts.cache - an object mapping sources to their encoder-differential state.
• opts.mapCommentType - defaults to line. will generate sourcemaps with //#, any other value will generate sourcemaps with /*# */.
• opts.mapCommentCharset - defaults to utf-8.
• opts.sourceRoot - a string of the sourcemap sourceRoot.
• opts.file - a string of the sourcemap file.

Available methods:

• sm.addFileSource(filename, source) - append a file and its inlined sourcemap if available. returns source with the sourcemap comment removed.
• sm.addSpace(source) - append files that don't have their own source mapping, but need to push the line/column count.
• sm.comment() - return the sourcemap comment.
• sm.generate() - return the sources and the sourcemap comment.
