Our open-source in Hacktoberfest 2020

Our team actively supports open-source movement, but unfortunately, sometimes we don't have enough time for implementing new features in our OSS. So, initiatives like Hacktoberfest could be really helpful for us. In this article, I will show up the most notable issues.

React Figma

react-figma is our flagship open-source project, this is a React renderer into Figma. The project has already participated in Hacktoberfest last year and got new contributors. There is a contribution guide that could be helpful for newcomers.

Text, Colors etc. Styles supporting

Figma Styles feature is a really helpful. We actively use in our projects:

Test Styles select

Figma has API for creating styles, but React Figma hasn’t support it. Of course, it’s possible to write something like this:

const style = figma.createTextStyle();
style.fontName = "Roboto";
style.fontSize = 16;
<Text textStyleId={} />

but this code is not compatible with react-native API and text styles will be re-created if the plugin relaunches.

How to access figma.getLocaleXStyles() #345


Thanks for this library.

I'm currently investigating how to use and build Locale Styles image

I manage to access the figma API from code.ts and create all my styles.

I am now hoping to reuse them from my component without success. Am I missing something in the docs ?

const Palettes: React.FC<PalettesProps> = ({ ...props }) => {
  const theme = useTheme();
  const styles = figma.getLocalPaintStyles(); // throw figma is not defined at runtime
  return ...

If it's not available yet, happy to help through a PR with your guidance ;)

React Native APIs supporting

React Native compatibility is the one of the most useful features of react-figma. But we haven't implemented all RN APIs yet.

There are issues about it:

Implementing Error Boundaries or RedBox

React supporst Error Boundaries components to allow debugging purposes. But React Figma doesn't have this out-of-the-box support:

Implementing Error Boundaries or RedBox. #83

Should introduce react Error Boundaries components to allow for debugging purposes.

Error Boundaries can have a back up render function that renders a Rectangle and Text component with the error and stack.

Reference: react-sketchapp RedBox component


react-fetch-hook is a React hook to use Fetch AP convenientlyI. There are some unclosed issues:

Abort fetch #25

Hi thank you for this great react fetch hook, Is there a way to make the fetch abortable and abort it when component is unmount ?

Thank you

isLoading = false with rapid requests #24

If rapid requests are issued, like in an autocomplete scenario, isLoading will be false even when hanging requests are still open.

In other words:

  1. Setup a series of fetches quickly as the user is typing
  2. When a new fetch is issued, cancel the previous fetches
  3. isLoading will === false even though current fetch is still open
  4. results will still correctly return

Rerender triggered three times when dependencies change #29

This may be related to #24. Whenever I change the dependencies, I get three rerenders where I only expect to see two.


  1. Change dependencies.
  2. Render with isLoading === true, data === null
  3. Render with isLoading === false, data === <new-result>


  1. Change dependencies.
  2. Render with isLoading === false, data === <previous-result>
  3. Render with isLoading === true, data === <previous-result>
  4. Render with isLoading === false, data === <new-result>

I don't care so much about data containing the previous result, and changing just that to null with no additional changes would be bad. But why am I getting that first rerender which is a copy of the previous call result? I would expect calling the hook with changed dependencies to immediately return with isLoading === true.

To be clear, everything works okay. The downside is the additional no-op render due to the first result being identical to the previous result. I assume the fetch call has been made by that point, and yet the hook tells me it's not loading. Is there any way to avoid that (step 2 above)?


react-media-hook is a React Hook for Media Queries.

Helpers for creating queries

Helpers for creating queries could be a very useful feature. E.g. instead of

const isDark = useMediaPredicate("(prefers-color-scheme: dark)");

will be much better something like this:

const isDark = useDark();

Helpers for creating queries #13


useMediaPredicate("(prefers-color-scheme: dark)"


  • useDark
  • useMediaPredicate({prefersColorScheme: "dark"})

GitHub logo lessmess-dev / gen-flow-files

Script for transform javascript files to flowtype definition files


npm version npm downloads

This is a script which finds .js files with @flow annotation, extract flow definitions and save to specific folder.

As example, <inputDir>/example.js

// @flow
extract function foo(arg1: number, arg2: string): string {
    // some code here

will be transformed to <outputDir>/example.js.flow:

// @flow
declare extract function foo(arg1: number, arg2: string): string;
Sponsored by Lessmess


Install it with yarn:

yarn add gen-flow-files

Or with npm:

npm i gen-flow-files --save


As part of build process

scripts": {
    "flow": "flow",
    "build:flow": "gen-flow-files src --out-dir dist",

transfrom all .js files from src to .js.flow files and save them at dist.

As command

npx gen-flow-files <inputDir> --out-dir <outputDir&gt

transfrom all .js files from <inputDir> to .js.flow files and save them…


We think Hactoberfest is a great initiative, but it doesn't support spam PRs for t-short. Do you know awesome repositories that looking for contributors? Propose them in the comments! 🙌

Happy coding!
