Code in Framer

Framer X lets everyone do advanced interactive design without using a line of code; either by using the interactive tools, or by using components from the store that were built by others.

If you know React and are looking to build your own components, you can use code to make them do anything, just like any other component you ever wrote.

Framer X uses code in a different way than you might be used to from a design tool. Framer X does not generate code for you from your designs, but instead it uses code that you wrote to compose interfaces. This is better because:

  • You can share code with production. Your design component can be the exact same version that runs on your production website, so there is a single source of truth.
  • Auto generated code ultimately almost never ends up in production, developers want to have full control over every aspect and will typically always (re)write it by hand according to internal standards and processes.

Types of Code

Framer uses code in two distinct places: components and functions.

Components are React Components. They are parts of an interface that you can compose into large applications. The code that you typically write for components concern just that component. So for a slider, it would contain the code to draw the knob and rails, plus the code to handle the scrubbing, nothing more than that.

Code overrides facilitate communication between components. To turn components into an app, they need to communicate. So the slider has to maybe change the position of something. Code overrides allow you to override any properties before the components get previewed, update or respond to application state, and attach event handlers to make things interactive.

Note: code overrides are very minimal on purpose so that you can use them any way you like, and do things like bring your own state management like Redux if you want, or no state management at all.


All code in Framer is expressed in plain React using JavaScript ES6. A component can be as simple as just one html tag with some css, all the way to a very complex media player with rich interactions. This also means that people with a variety of skills can make components. If you know basic web development you can learn to build them in ten minutes. If you are an advanced engineer that knows React, you don’t have to learn anything new, everything will just work like you expect.

Note: Under the hood Framer X actually uses TypeScript, a typed version of JavaScript. Types help to manage larger applications and helps us to offer really great auto complete for editors, but TypeScript will become completely optional so that you will also be able to just write ES6 if you like.

Note: Although there might be a way to create React Native applications in Framer in the future, we don’t offer an official way today. You are of course free to explore how far you can come yourself. Our open source Framer library should contain everything you need to get started.

Editor Setup

Framer X relies on an external editor for writing code. Any editor will work, but we strongly suggest one that supports TypeScript (for auto complete). Our personal favourite by far is VSCode by Microsoft with the optional Prettier extension installed so your code is always formatted consistently.

Changing your default editor

  • Go to any .ts / .tsx file in your Finder.
  • Right-click and choose "Get Info".
  • At the "Open With…" section you can select your editor.
  • Click "Change All…" and then choose "Continue".

You may have to restart your editor in order for Framer X to notice the new default choice. It may still serve you with an error if you were in the middle of updating your code editor to its latest version. If that happens then re-try the steps given above, select the newest version (if there are two versions) and it should work.


If you edit any Framer X code it automatically gets updated in Framer X when you save the file. So components get re-rendered on the canvas and in the preview, and functions get updated under the hood.

If you get an error, the component will turn red and display the error message with optional suggestions where to look for the exact error. There are two types of errors:

  • Syntax error – You likely made a typo in your code, and the computer does not understand it. The most common ones are capitalisation errors, missing brackets, and commas.
  • Runtime error – Something went wrong while running the code. This can be anything really.

Errors are listed in the right bottom of your screen. To deeper investigate errors, you can use the web inspector by clicking on the error counter, or right clicking in the Preview and choosing “Inspect Element”.

TBD: Editing components from the store.

Note: we recommend a window manager utility like Magnet to help with managing your windows efficiently between code and canvas.

Note: we might introduce a code editor back in Framer in the future, but for now we chose to focus on the rest of the app. Building an editor as great as VSCode is very hard, and we were noticing many users in legacy Framer already using their own editor, bypassing the built-in one.

Note: Because the code runs in both the canvas and preview, there are two inspectors. You’ll likely most often need the one for preview.
