# Redux Duplicate Action Monitor This is a redux middleware that detects duplicate actions & shows this in the console. Ideal for ensuring good redux practices. Development use only! If there is a duplicate action you will see this in the browser console: ``` [redux-duplicate-actions] A duplicate action has been detected. [redux-duplicate-actions] Unique action hash: e6d0f668 [redux-duplicate-actions] Unpacked action: {type: 'SET_DATA', payload: {…}} [redux-duplicate-actions] Original action: {type: 'SET_DATA', payload: ƒ} // Read below ``` If your payload is a function the middleware we will attempt to unpack it and show you the actual data. It does this by simply running the function against `store.getState()`. So effectively `action.payload(store.getState())`. If this fails it will do the comparison as normal. _Supports Node 10.x +_ ### Installation Run this in the terminal: ```bash npm install --save-dev redux-duplicate-actions ``` or ```bash yarn add -D redux-duplicate-actions ``` ## Usage Supported options: `fatal` (type: boolean) - if `true`, will throw an error when a duplicate action is detected. Default is `false`. `logLevel` (type: 'log' | 'warn' | 'error') - the level of logging to the console. Default is `"warn"`. `payloadKey` (type: string) - the key to use to get the payload for the redux action. Default is `"payload"`. `unpackPayloadIfFunction` (type: boolean) - if true, will attempt to unpack the payload if it is a function. Default is `true`. ```js if (__DEV__) { // To thrown fatal error on duplicate action const reduxDuplicateActions = require("redux-duplicate-actions")({ fatal: true, }); reduxMiddleware.push(reduxDuplicateActions); // To log duplicate action as warning const reduxDuplicateActions = require("redux-duplicate-actions")({ fatal: false }); reduxMiddleware.push(reduxDuplicateActions); } ``` ## Test Run the following commands to test the module: `yarn install && yarn test` ## Contributing All contributions are very welcome, please read my [CONTRIBUTING.md](https://github.com/daviemakz/redux-duplicate-actions/blob/master/CONTRIBUTING.md) first.
