Please follow it in all your interactions with the project. Before contributing, please read the [code of conduct](./CODE_OF_CONDUCT.md). 6 | 7 | ## Development workflow 8 | 9 | To get started with the project, run `yarn` in the root directory to install the required dependencies for each package: 10 | 11 | ```sh 12 | yarn 13 | ``` 14 | 15 | > While it's possible to use [`npm`](https://github.com/npm/cli), the tooling is built around [`yarn`](https://classic.yarnpkg.com/), so you'll have an easier time if you use `yarn` for development. 16 | 17 | While developing, you can run the [example app](/example/) to test your changes. Any changes you make in your library's JavaScript code will be reflected in the example app without a rebuild. If you change any native code, then you'll need to rebuild the example app. 18 | 19 | To start the packager: 20 | 21 | ```sh 22 | yarn example start 23 | ``` 24 | 25 | To run the example app on Android: 26 | 27 | ```sh 28 | yarn example android 29 | ``` 30 | 31 | To run the example app on iOS: 32 | 33 | ```sh 34 | yarn example ios 35 | ``` 36 | 37 | To run the example app on Web: 38 | 39 | ```sh 40 | yarn example web 41 | ``` 42 | 43 | Make sure your code passes TypeScript and ESLint. Run the following to verify: 44 | 45 | ```sh 46 | yarn typecheck 47 | yarn lint 48 | ``` 49 | 50 | To fix formatting errors, run the following: 51 | 52 | ```sh 53 | yarn lint --fix 54 | ``` 55 | 56 | Remember to add tests for your change if possible. Run the unit tests by: 57 | 58 | ```sh 59 | yarn test 60 | ``` 61 | 62 | 63 | ### Commit message convention 64 | 65 | We follow the [conventional commits specification](https://www.conventionalcommits.org/en) for our commit messages: 66 | 67 | - `fix`: bug fixes, e.g. fix crash due to deprecated method. 68 | - `feat`: new features, e.g. add new method to the module. 69 | - `refactor`: code refactor, e.g. migrate from class components to hooks. 70 | - `docs`: changes into documentation, e.g. add usage example for the module.. 71 | - `test`: adding or updating tests, e.g. add integration tests using detox. 72 | - `chore`: tooling changes, e.g. change CI config. 73 | 74 | Our pre-commit hooks verify that your commit message matches this format when committing. 75 | 76 | ### Linting and tests 77 | 78 | [ESLint](https://eslint.org/), [Prettier](https://prettier.io/), [TypeScript](https://www.typescriptlang.org/) 79 | 80 | We use [TypeScript](https://www.typescriptlang.org/) for type checking, [ESLint](https://eslint.org/) with [Prettier](https://prettier.io/) for linting and formatting the code, and [Jest](https://jestjs.io/) for testing. 81 | 82 | Our pre-commit hooks verify that the linter and tests pass when committing. 83 | 84 | ### Publishing to npm 85 | 86 | We use [release-it](https://github.com/release-it/release-it) to make it easier to publish new versions. It handles common tasks like bumping version based on semver, creating tags and releases etc. 87 | 88 | To publish new versions, run the following: 89 | 90 | ```sh 91 | yarn release 92 | ``` 93 | 94 | ### Scripts 95 | 96 | The `package.json` file contains various scripts for common tasks: 97 | 98 | - `yarn bootstrap`: setup project by installing all dependencies and pods. 99 | - `yarn typecheck`: type-check files with TypeScript. 100 | - `yarn lint`: lint files with ESLint. 101 | - `yarn test`: run unit tests with Jest. 102 | - `yarn example start`: start the Metro server for the example app. 103 | - `yarn example android`: run the example app on Android. 104 | - `yarn example ios`: run the example app on iOS. 105 | 106 | ### Sending a pull request 107 | 108 | > **Working on your first pull request?** You can learn how from this _free_ series: [How to Contribute to an Open Source Project on GitHub](https://app.egghead.io/playlists/how-to-contribute-to-an-open-source-project-on-github). 109 | 110 | When you're sending a pull request: 111 | 112 | - Prefer small pull requests focused on one change. 113 | - Verify that linters and tests are passing. 114 | - Review the documentation to make sure it looks good. 115 | - Follow the pull request template when opening a pull request. 116 | - For pull requests that change the API or implementation, discuss with maintainers first by opening an issue. 117 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2023 Lukasz Kurant 4 | Permission is hereby granted, free of charge, to any person obtaining a copy 5 | of this software and associated documentation files (the "Software"), to deal 6 | in the Software without restriction, including without limitation the rights 7 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 8 | copies of the Software, and to permit persons to whom the Software is 9 | furnished to do so, subject to the following conditions: 10 | 11 | The above copyright notice and this permission notice shall be included in all 12 | copies or substantial portions of the Software. 13 | 14 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 15 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 16 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It works with Expo. 4 | 5 | - 🎙️ Works with Expo 6 | - 🪽 Easy usage 7 | - ⚠️ `react-native-reanimated` required 8 | 9 | ### Motivation 10 | 11 | There are currently many libraries available for Collapsible components, but they are either no longer supported or do not implement the latest innovations in the React Native architecture. Hence the need for a library that works with the new architecture based on the React Native Reanimated API V3 and allow to have always native performance. 12 | 13 | ### Installation 14 | 15 | ```sh 16 | yarn add react-native-fast-collapsible 17 | ``` 18 | 19 | This library has a peer dependency on react-native-reanimated has to be installed, linked and configured into your project. Follow [react-native-reanimated](https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/getting-started) to install the dependency. 20 | 21 | ### Usage / API 22 | 23 | #### Collapsible component 24 | 25 | A simple component that enables an animated action to hide and show content. 26 | 27 | https://github.com/user-attachments/assets/e74700c5-d1b9-4559-9b9b-940bd02d684f 28 | 29 | #### Example 30 | 31 | ```jsx 32 | import React, { useState } from 'react';

39 | 40 | const toggleVisibility = () => { 41 | setVisibility((previous) => !previous); 42 | }; 43 | 44 | return ( 45 | 46 | 47 | Expand / Collapse 48 | 49 | 50 | 51 | Lorem ipsum.... 52 | 53 | 54 | );
