Online JavaScript Full-Stack Bootcamp in Barcelona Code School

JavaScript Full-Stack Online Mentored Bootcamp in Barcelona Code School

Become a full-stack developer and build web and mobile apps powered by JavaScript

What is a web/mobile developer?

A web/mobile developer builds, productionizes, optimizes and maintains web and mobile applications.

A web application is a website with functionality and user interactions, which is not only displaying static content but also allows users to do something. For example, YouTube (users can upload videos, watch them, comment, etc..), Reddit (users can post, read, comment, etc...), Amazon (users can buy products, sellers can sell them, etc...) are all web applications.

A mobile app is any app you can install in your mobile phone. For example, Weather, Notes, Mail, TikTok, Telegram, Netflix and so on...

Our course is focused primarly on developing web and mobile apps (for both iOS and Android) with the JavaScript MERN stack which includes React, Node, Express, mongoDB and of course JavaScript, HTML, CSS + React Native for mobile developemnt.

Bootcamps since 2017 with continuous updates and improvements

How does it work

  1. Choose a starting date and sign up from this page to reserve your place
  2. Receive the pre-course materials to prepare before the bootcamp starts. We estimate it to take 40-80 hours if you start from absolutely zero level of knowledge of JavaScript, HTML and CSS
  3. Get all the main course materials, including text and video lessons
  4. From day one of the bootcamp start learning at your own pace extending the duration of the course if needed
  5. We provide support via support platform, chat, track you progress and give feedback
  6. Schedule weekly 1:1 sessions with your mentor to resolve any current issues, get extra explainations and ask any questions
  7. The curriculum, projects, exercises and the outcomes are identical with the in-person version of the bootcamp

International students

You are welcome!

A lot of our students are coming from abroad. The course is in English so there is no language barrier. And if you will need help with visa we can send you an acceptance letter to attach to your visa application!


2100€: 9 weeks, full-time

If you choose to do the course full-time and will be well-prepared you can finish it in 9 weeks.

2500€: 13 weeks, part-time

If you are doing it in a slightly less intensive you will most likely complete it in 13 weeks This is the most balanced option.

2900€: 16 weeks, part-time

For students combining the bootcamp with part-time or full-time job 16 weeks are more realistic.

Optional weekly extensions available

If you will need more time and mentors support to finish the bootcamp you can extend it on a weekly basis for 120€ per week which allows you to keep learning at your own pace while continuing getting all the support and guidance we provide.

In this way you can complete the bootcamp according to your schedule and learning speed – from full-time intensive 9-week duration, which is the same as we do with in-person group on campus, to a longer timeframe.
