redux-modular-fetch-middleware\n\u003e A modular redux middleware for using fetch\n\n---\n## Table of Contents\n1. [Getting Started](#getting-started)\n2. [Documentation](#documentation)\n3. [Best Practices](#best-practices)\n---\n\n### Getting Started\n- Download `redux-modular-fetch-middleware` using `npm i redux-modular-fetch-middleware` or `yarn add redux-modular-fetch-middleware`\n- Apply the middleware using the `redux-modular-fetch-middleware` default export, like so...\n```javascript\nimport { createStore, applyMiddleware } from 'redux'\nimport fetchMiddleware from 'redux-modular-fetch-middleware';\n...\napplyMiddleware(fetchMiddleware);\n```\n- Define a `fetch` object with a `url` property on the dispatch you want to call fetch\n```javascript\nconst actionCreatorMethod = () =\u003e ({\n    fetch: {\n        url: 'https://someurl.com'\n    },\n    type: SOME_ACTION_TYPE\n});\n```\nThat's it! A `fetch` object with a `url` property is all you need to call fetch on an action.\n- `fetch` The required object on a dispatch call to call fetch\n- `url` The url that will be called by fetch\n\n\u003cbr /\u003e\n\nYou can define what the request `method`, `body`, and `header` look like. In fact, any options that you can define in fetch natively will be passed on just as if you were calling fetch yourself.\n- `options` Fetch options with properties like `method`, `header`, and `body`. By default, `GET` will be used as the request method\n```javascript\nconst setUserActionCreator = () =\u003e ({\n    fetch: {\n        options: {\n            body: {\n                user: {\n                    name: 'First Last',\n                    address: '123 Main St.' \n                }\n            },\n            method: 'POST'\n        },\n        url: 'https://someapi.com/user'\n    },\n    type: SET_USER_REQUEST\n});\n```\n\n\u003cbr /\u003e\n\nIf you're retrieving data, you can define what response method will be used to retrieve that data.\n- `responseMethod` The [response method](https://developer.mozilla.org/en-US/docs/Web/API/Body) used to retrieve data. By default, `json` will be used as the response method if the `header` content-type is 'application/json'. **Warning:** If a `responseMethod` is provided and your fetch call returns a response that is not resolvable by the `responseMethod` provided, the Promise will be rejected.\n```javascript\nconst getProfilePicActionCreator = (userId) =\u003e ({\n    fetch: {\n        responseMethod: 'blob',\n        url: `https://someapi.com/user/${userId}/profilePic`\n    },\n    type: GET_PROFILE_PIC_REQUEST\n});\n```\n\n\u003cbr /\u003e\n\nBeing able to call fetch without being able to access the data or error isn't very useful. Those options are provided through the properties shown below.\n- `onFailure` The function that will be called if the fetch request fails. Called with `dispatch`, `getState`, and `error`\n- `onSuccess` The function that will be called if the fetch request succeeds. Called with `dispatch`, `getState`, and `data`\n\nYou are also given the `store`'s current `getState` and `dispatch` function to notify your reducers your request was successful or unsuccessful.\n\n```javascript\nconst getProfilePicActionCreator = (userId) =\u003e ({\n    fetch: {\n        onFailure: (dispatch, getState, error) =\u003e {\n            dispatch({\n                error: error,\n                type: GET_PROFILE_PIC_FAILURE\n            });\n        },\n        onSuccess: (dispatch, getState, data) =\u003e {\n            dispatch({\n                data: data,\n                type: GET_PROFILE_PIC_SUCCESS\n            });\n        },\n        responseMethod: 'blob',\n        url: `https://someapi.com/user/${userId}/profilePic`\n    },\n    type: GET_PROFILE_PIC_REQUEST\n});\n```\n\n\u003cbr /\u003e\n\nYou can even define what fetch implementation you would like the middleware to use when applying the middleware.\n```javascript\nimport crossFetch from 'cross-fetch';\nimport fetchMiddleware from 'redux-modular-fetch-middleware';\n...\napplyMiddleware(fetchMiddleware(crossFetch));\n```\nThis can be especially useful when wanting to set global options in your fetch request like `header` and `credentials`. By default, `window.fetch` will be used as the fetch implementation. \n\n---\n\n### Documentation\n\n**Required Object**\n- `fetch` The required object on a dispatch call to call fetch\n\n**Required Properties on `fetch` Object**\n- `url` The url that will be called by fetch\n\n**Optional Properties on `fetch` Object**\n- `onFailure` The function that will be called if the fetch request fails. Called with `dispatch`, `getState`, and `error`\n- `onSuccess` The function that will be called if the fetch request succeeds. Called with `dispatch`, `getState`, and `data`\n- `options` Fetch options with properties like `method`, `header`, and `body`. By default, `GET` will be used as the request method\n- `responseMethod` The [response method](https://developer.mozilla.org/en-US/docs/Web/API/Body) used to retrieve data. By default, `json` will be used as the response method if the `header` content-type is 'application/json'. **Warning:** If a `responseMethod` is provided and your fetch call returns a response that is not resolvable by the `responseMethod` provided, the Promise will be rejected.\n    - 'arrayBuffer'\n    - 'blob'\n    - 'formData'\n    - 'json'\n    - 'text'\n\n**Fetch Implementation**\n\nThe fetch implementation can be defined by passing it in as the parameter when applying the middleware. By default, `window.fetch` will be used as the fetch implementation.\n\n---\n\n### Best Practices\n\n**Async Actions**\n\n[Redux docs](https://redux.js.org/advanced/async-actions#actions) suggest using three actions for an asynchronous request: an action indicating your request began, an action indicating your request succeeded, and an action indicating your request failed. Below is an example of how to heed this suggestion using `redux-modular-fetch-middleware`.\n```javascript\nconst getUserActionCreator = (userId) =\u003e ({\n    fetch: {\n        onFailure: (dispatch, getState, error) =\u003e {\n            dispatch({\n                error: error,\n                type: GET_USER_FAILURE\n            });\n        },        \n        onSuccess: (dispatch, getState, data) =\u003e {\n            dispatch({\n                data: data,\n                type: GET_USER_SUCCESS\n            });\n        },\n        url: `https://someapi.com/user/${userId}`\n    },\n    type: GET_USER_REQUEST\n});\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrigonzalez%2Fredux-modular-fetch-middleware","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbrigonzalez%2Fredux-modular-fetch-middleware","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrigonzalez%2Fredux-modular-fetch-middleware/lists"}
