Read more in the [Zustand readme](https://github.com/pmndrs/zustand#persist-middleware). 4 | 5 | # Zustand persist 6 | 7 | Persist and rehydrate state works on react and react native. 8 | 9 | [Zustand](https://github.com/react-spring/zustand) is a small, fast and scaleable bearbones state-management solution. 10 | 11 | This library is inspired by [https://github.com/rt2zz/redux-persist](https://github.com/rt2zz/redux-persist). 12 | 13 | Contributions are Welcome 14 | 15 | [![Build Status](https://travis-ci.org/roadmanfong/zustand-persist.svg?branch=master)](https://travis-ci.org/roadmanfong/zustand-persist) [![npm version](https://img.shields.io/npm/v/zustand-persist.svg?style=flat-square)](https://www.npmjs.com/package/zustand-persist) [![npm downloads](https://img.shields.io/npm/dm/zustand-persist.svg?style=flat-square)](https://www.npmjs.com/package/zustand-persist) 16 | 17 | ```cli 18 | $ npm install zustand-persist 19 | $ yarn add zustand-persist 20 | ``` 21 | 22 | Try [Demo](https://codesandbox.io/s/zustand-persist-example-5u3ry?file=/src/App.js) Here 23 | 24 | ## Middleware 25 | 26 | ```ts 27 | // if in react native 28 | // import AsyncStorage from '@react-native-community/async-storage' 29 | 30 | const { persist, purge } = configurePersist({ 31 | storage: localStorage, // use `AsyncStorage` in react native 32 | rootKey: 'root', // optional, default value is `root` 33 | }) 34 | 35 | const useStore = createStore( 36 | persist({ 37 | key: 'auth', // required, child key of storage 38 | allowlist: ['isAuthenticated', 'user'], // optional, will save everything if allowlist is undefined 39 | denylist: [], // optional, if allowlist set, denylist will be ignored 40 | }, (set) => ({ 41 | isAuthenticating: false, 42 | isAuthenticated: false, 43 | user: undefined, 44 | login: async (username, password) =>{ 45 | set((state) => ({ isAuthenticating: true })) 46 | const { user } = await webLogin(username, password) 47 | set((state) => ({ 48 | isAuthenticated: true, 49 | isAuthenticating: false, 50 | user, 51 | })), 52 | } 53 | })) 54 | ) 55 | ``` 56 | 57 | ## PersistGate 58 | 59 | ```tsx 60 | function App() { 61 | // Must call useStore to bootstrap persistence or will stop on loading screen 62 | useStore() 63 | return ( 64 | { 66 | console.log('onBeforeLift') 67 | }} 68 | loading={}> 69 | 70 | 71 | ) 72 | } 73 | ``` 74 | 75 | ## Limitations 76 | Zustand allows any valid JavaScript data types to set in the store, such as Set, Map, or functions. Both `localStorage` and `AsyncStorage` require that all values set in them be serializable, or converted into string form for storage. This means if you wish to persist the contents of your store all of its values need to be serializable. Any values which are not serializable will be silently absent upon hydration. 77 | 78 | A note on storing actions (functions): your actions are safe as long as they exist in the initial state during store creation. The hydration process merges initial state with stored state. 79 | 80 | ## Todo 81 | 82 | - enhanced removing root logic 83 | -------------------------------------------------------------------------------- /babel.config.js: -------------------------------------------------------------------------------- 1 | module.exports = { 2 | presets: [ 3 | ['@babel/preset-env', { targets: { node: 'current' } }], 4 | '@babel/preset-typescript', 5 | '@babel/preset-react', 6 | ], 7 | } 8 | -------------------------------------------------------------------------------- /cspell.json: -------------------------------------------------------------------------------- 1 | // cSpell Settings 2 | { 3 | "version": "0.1", 4 | "language": "en", 5 | "words": [ 6 | "zustand", 7 | "denylist", 8 | "allowlist", 9 | "fong", 10 | "flowtype", 11 | "browserslist" 12 | ] 13 | } 14 | -------------------------------------------------------------------------------- /example/.gitignore: -------------------------------------------------------------------------------- 1 | # See https://help.github.com/articles/ignoring-files/ for more about ignoring files. 2 | 3 | # dependencies 4 | /node_modules 5 | /.pnp 6 | .pnp.js 7 | 8 | # testing 9 | /coverage 10 | 11 | # production 12 | /build 13 | 14 | # misc 15 | .DS_Store 16 | .env.local 17 | .env.development.local 18 | .env.test.local 19 | .env.production.local 20 | 21 | npm-debug.log* 22 | yarn-debug.log* 23 | yarn-error.log* 24 | -------------------------------------------------------------------------------- /example/README.md: -------------------------------------------------------------------------------- 1 | # Zustand Persist Example 2 | 3 | yarn install on project root 4 | build in the project root for `/lib` document, then `cd example` 5 | 6 | ```cli 7 | $ yarn start 8 | ``` 9 | -------------------------------------------------------------------------------- /example/config/env.js: -------------------------------------------------------------------------------- 1 | 'use strict'; 2 | 3 | const fs = require('fs'); 4 | const path = require('path'); 5 | const paths = require('./paths'); 6 | 7 | // Make sure that including paths.js after env.js will read .env variables. 8 | delete require.cache[require.resolve('./paths')]; 9 | 10 | const NODE_ENV = process.env.NODE_ENV; 11 | if (!NODE_ENV) { 12 | throw new Error( 13 | 'The NODE_ENV environment variable is required but was not specified.' 14 | ); 15 | } 16 | 17 | // https://github.com/bkeepers/dotenv#what-other-env-files-can-i-use 18 | const dotenvFiles = [ 19 | `${paths.dotenv}.${NODE_ENV}.local`, 20 | // Don't include `.env.local` for `test` environment 21 | // since normally you expect tests to produce the same 22 | // results for everyone 23 | NODE_ENV !== 'test' && `${paths.dotenv}.local`, 24 | `${paths.dotenv}.${NODE_ENV}`, 25 | paths.dotenv, 26 | ].filter(Boolean); 27 | 28 | // Load environment variables from .env* files.
