Resource file for locating the mappings

As a beginner in sourcemapping, I have been tasked with saving the sourcemap in an external file. However, up to this point, I have only been able to concatenate the sourcemap to the minified .js file. What changes should I make to my approach? Am I missing something essential here?

return gulp.src(sourceFiles)
           .pipe(sourcemaps.init())
           .pipe(concat('minifiedJS.min.js'))
           .pipe(sourcemaps.write('maps'))
           .pipe(gulp.dest(destinationFolder))

Answer №1

According to information from the documentation regarding gulp-sourcemaps:

If you want to generate external source map files, specify a path relative to the destination in the sourcemaps.write() method.

Consider setting the target path for the source maps as the current directory (.).

return gulp.src(sourceFiles)
           .pipe(sourcemaps.init())
           .pipe(concat('minifiedJS.min.js'))
           .pipe(sourcemaps.write('.'))
           .pipe(gulp.dest(destinationFolder))
