In-browser markdown editor

In this project, you'll build a fully-functional in-browser markdown editor application with a light/dark mode toggle. It's also perfect to build as a full-stack app!

πŸ“Brief

Your challenge is to build out this in-browser markdown editor and get it looking as close to the design as possible.

You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.

We provide the data in a local data.json file, so use that to populate the content on the first load. If you want to take it up a notch, feel free to build this as a full-stack CRUD application!

Your users should be able to:

  • Create, Read, Update, and Delete markdown documents
  • Name and save documents to be accessed as needed
  • Edit the markdown of a document and see the formatted preview of the content
  • View a full-page preview of the formatted content
  • View the optimal layout for the app depending on their device's screen size
  • See hover states for all interactive elements on the page
  • Bonus: If you're building a purely front-end project, use localStorage to save the current state in the browser that persists when the browser is refreshed
  • Bonus: Build this project as a full-stack application

Download the project and go through the README.md file. This will provide further details about the project and help you get set up.

πŸ—ƒAssets provided

  • Sketch and Figma design files
  • Mobile, tablet & desktop layouts
  • Professional design system for colors, fonts, etc.
  • Optimized image assets
  • README file to help you get started
  • HTML file with pre-written content

πŸ’‘Ideas to test yourself

  1. Extend the project to add your own functionality e.g. add support for images, optimise for saving the formatted markdown as a PDF

  2. Train your eye for detail by getting your solution as close to the design as you can

  3. Use a JavaScript framework/library to practice building using components

  4. Try estimating the time it will take for you to build the project. Then see if the time taken matches up to your estimate. Project estimations are a skill that is often overlooked but is important for professional developers

Challenge FAQs

How can I get help if I'm stuck on a challenge?

The best (and quickest) way to get help on a challenge is in our Discord server. There are thousands of other developers in there, so it's a great place to ask questions. We even have a dedicated "help" channel! If you haven't joined yet, you can get an invite to our Discord server here.

How do I submit my solution?

We'd recommend reading our complete guide to submitting solutions . If you get stuck and need help, please feel free to ask questions in our Discord server, and we'll help you submit your project.

Is there an official solution I can take a look at?

We don't provide "official" solutions for the challenges. This is because there is no single perfect way to complete a challenge. Instead, you're encouraged to review other people's code in the community. You can learn so much by seeing how other people have approached the same challenges and giving them feedback.

Do I get a code review when I post my solution?

Frontend Mentor is a collaborative learning community where everyone can give feedback to each other. If you'd like to receive feedback from the community, please be sure to post a question when you submit your solution. The more specific you can be, the better. Being clear with your questions means you're much more likely to receive valuable feedback from others.

Can I use libraries/frameworks on these projects?

Yes! Our challenges provide professional designs but there are no rules on what tools to use. So feel free to use anything you like to build your projects.

Can I use these projects in my portfolio?

Definitely! Please do feel free to use whatever you build in your portfolio. Helping developers add professional-looking projects to their portfolio was one of the reasons we created this platform!

How often are new challenges added?

We launch a new challenge every two weeks. We alternate between free and premium challenge launches, so we launch one free and one premium challenge each month.

What is the difference between the desktop-design, mobile-design, and desktop-preview images in my starter code?

The desktop-design and mobile-design images show you how the layout should look at large and small screen sizes. The desktop design is 1440px wide, and the mobile design is 375px. However, try building projects to look good on all screen sizes. The desktop-preview image is a preview image used in the README file. You don’t need to reference this while building the project.

Can I use these challenges within my own free or commercial content/tutorials/projects?

Please visit our License page to learn more about how our challenges can be used within your own content. If you're unsure about anything, please feel free to contact us at [email protected] and we'll be more than happy to answer your questions.
