Migrate to v2 now since v1 has many bugs and is deprecated. ## Index ## ### Catalog ### * [Introduce](#introduce) * [Installation](#installation) * [Best Practices](#best-practices) * [API](#api) * [Basic Options](#basic-options) * [Life Circle Functions](#life-circle-functions) * [Custom Buttons](#custom-buttons) * [Component Functions](#component-functions) * [Examples](#examples) * [Author](#author) * [License](#license) ## Introduce ## A **Structure-Only**, **UI-Customizable** and **Modern** file upload component for React which support IE10+ and basically support IE9, requiring node4+. ## Installation ## `npm install react-upload-file -S` ### Best Practices ### + It's recommened to use arrow function to avoid 'this' problems. + Queries in `baseUrl` will be ignored if `query` is set. ## API ## ### Basic Options ### ```js options: { baseUrl: 'xxx', ... } ``` `options` is an attribute of `ReactUploadFile`. The properties of `options` are: name | type | default | note ------------ | ------------- | ------------ | ------------ baseUrl | String | '' | url query | Object/Function | undefined | Queries that appended after `baseUrl`. When it is a function, use its return value body | Object/Function | undefined | Key-values that need to add to formData besides files. When it is a function, use its return value dataType | String | 'json' | Accept type of response(json or text) timeout | Number | 0 | Timeout of the request. Callback function `uploadError` will be triggered and an object { type: 'TIMEOUTERROR', message: 'timeout' } will be returned as the argument. Default to 0 meaning no limit accept | String | undefined | Limit the type of file multiple | Boolean | false | Allow multi-upload or not numberLimit | Number | 0 | Limit how many files can be uploaded a time, 0 means no limit. fileFieldName | String/Function | undefined | Determine the field name of file. If it is a function, which will receive each file object as argument, use its return value. Default to file's name withCredentials | Boolean | false | Same as 'xhr.withCredentials' requestHeaders | Object | undefined | Key-values that will be set using 'xhr.setRequestHeader(key, value)' userAgent | String | window.navigator.userAgent | Used to set the userAgent string with serverside rendering isomorphic applications(required when rendering on the server) ### Life Circle Functions ### Also set as the properties of options. #### beforeChoose() #### Triggered immediately after clicking the `chooseFileButton` but before `didChoose`. Return true to continue or false to stop choosing. @param null @return {Boolean} Determine whether to continue uploading #### didChoose(files) #### The callback triggered after choosing. @param filelist {Filelist} The array contains files. @return **your return** #### beforeUpload(files) #### Triggered before uploading. Return true to continue or false to stop uploading. @param files {Filelist} The array contains files. @return {Boolean} Allow the upload action or not. #### didUpload(files, xhrId) #### Triggered after the request is sent(xhr send | form submit). @param files {Filelist | String} The array contains files. @param xhrId {Number} Id of this uploading xhr. Could be useful for `abort`. @return **your return** #### onAbort(xhrId) #### Triggered after you aborting a xhr. @param xhrId {Number} Id of the xhr aborted. @return **your return** #### uploading(progress) #### It will be triggered continuously when the file is uploading in moderns. @param progress {Progress} Progress instance，useful properties such as loaded and total can be found. @return **your return** #### uploadSuccess(res) #### Callback when upload succeed (according to the ajax simply). @param res {String} The response is formatted according to options.dataType(json or text). @return **your return** #### uploadError #### Callback when error occurred (according to the ajax simply). @param err {Object} If this is an error that caught by `try`, it will be an object with `type` and `message`. @return **your return** ### Custom Buttons ### You can display two of your custom buttons by setting two attributes of `ReactUploadFile` as mentioned before. #### chooseFileButton Component to choose files. #### uploadFileButton(optional) Component that triggers uploading. If not specified, files will be uploaded immediately after chosen. ```jsx } uploadFileButton={} /> ``` Will be rendered like this: ```jsx ``` If you don't set the `uploadFile` attribute, then `ReactUploadFile` will upload the files immediately after you choose files. ```jsx } /> ``` ### Component Functions ### Get component reference via ref. eg: ```jsx componentDidMount() { this.upload.manuallyChooseFile(); } todo() { this.upload.processFile(files => files) } render() { return ( {this.upload = upload;}} options={...} chooseFileButton={} uploadFileButton={} didChoose={this.todo} /> ); } ``` #### processFile(func) #### Process files with customed function. @param func {Function} Receive filelist as param @return null #### manuallyChooseFile() #### Do the same as clicking `chooseFileButton`. Only support modern browsers. @param null @return null #### manuallyUploadFile(files) #### Upload files manually, use this function. BeforeUpload() won't be triggered after the invoke of this function. @param files {Filelist} filelist that need to be uploaded, default to the filelist of chosen files. @return null #### abort(xhrId) #### Abort a xhr. Temporarily only works in modern browsers. @param xhrId {Number} If not passing an id, will abort the newest one. You can get it in `didUpload()`. ## Examples ## Simple example: ```jsx import ReactUploadFile from 'react-upload-file'; ... render() { /* set properties */ const options = { baseUrl: 'http://127.0.0.1', query: { warrior: 'fight' } } /* Use ReactUploadFile with options */ /* Custom your buttons */ return ( } uploadFileButton={} /> ); } ``` Most of the options may be set like: ```jsx options: { baseUrl: 'http://localhost:8080/upload', // query: { // category: '1', // _: Date().getTime() // }, query: (files)=>{ const l = files.length; const queryObj = {}; for(let i = l-1; i >= 0; --i) { queryObj[i] = files[i].name; } return queryObj; } // body: { // purpose: 'save' // }, body: (files)=>{ const l = files.length; const queryObj = {}; for(let i = l-1; i >= 0; --i) { queryObj[i] = files[i].name; } return queryObj; }, dataType: 'json', multiple: true, numberLimit: 9, accept: 'image/*', // fileFieldName: 'file', fileFieldName: (file) { return file.name; }, withCredentials: false, requestHeaders: { 'User-Agent': 'Warrior!' }, beforeChoose: () => { return user.isAllowUpload; }, didChoose: (files) => { console.log('you choose', typeof files == 'string' ? files : files[0].name); }, beforeUpload: (files) => { if (typeof files === 'string') return true; if (files[0].size < 1024 * 1024 * 20) { files[0].mill = mill; return true; } return false; }, didUpload: (files) => { console.log('you just uploaded', typeof files === 'string' ? files : files[0].name); }, uploading: (progress) => { console.log('loading...', progress.loaded / progress.total + '%'); }, uploadSuccess: (resp) => { console.log('upload success!'); }, uploadError: (err) => { alert(err.message); } } if (typeof window === 'undefined') { options.userAgent = this.props.userAgent; } ``` ## Author ## Warrior! from HCI@SCAU ## License ## MIT
