vinyl-sourcemaps-apply
Apply a source map to a vinyl file, merging it with preexisting source maps.
Usage:
var applySourceMap = require('vinyl-sourcemaps-apply');
applySourceMap(vinylFile, sourceMap);
Example (Gulp plugin):
var through = require('through2');
var applySourceMap = require('vinyl-sourcemaps-apply');
var myTransform = require('myTransform');
module.exports = function(options) {
function transform(file, encoding, callback) {
// generate source maps if plugin source-map present
if (file.sourceMap) {
options.makeSourceMaps = true;
}
// do normal plugin logic
var result = myTransform(file.contents, options);
file.contents = new Buffer(result.code);
// apply source map to the chain
if (file.sourceMap) {
applySourceMap(file, result.map);
}
this.push(file);
callback();
}
return through.obj(transform);
};
