Gulp, Reactify, and Babelify not transforming together

Posted by: admin January 30, 2018 Leave a comment

Questions:

This is my gulpfile code:

gulp.task('react', function () {
  browserify('app/src/main.jsx')
    .transform(reactify)
    .transform(babelify)
    .bundle()
    .pipe(source('app.js'))
    .pipe(streamify(uglify()))
    .pipe(gulp.dest('dist/js/'));
});

Only the first transform statement runs, and therefor throws an error due to the lack of additional transform (I’m writing in ES6 and JSX w/ react).

I’m at a complete loss and would really appreciate help.

Answers:

Reactify should no longer be used. You don’t say what version you are on, but as of Babel 6 “preset’s” are the standard way to achieve compilation.

Run the following

npm install save-dev babel-preset-react babel-preset-es2015

You should also make sure Babelify is up to date. Then your Gulp config becomes

var babelify = require("babelify");
gulp.task('react', function () {
  browserify('app/src/main.jsx')
    .transform(babelify, {presets: ["es2015", "react"]})
    .bundle()
    .pipe(source('app.js'))
    .pipe(streamify(uglify()))
    .pipe(gulp.dest('dist/js/'));
});
