如何解决停止查看reactjs中的文件夹更改
我正在一个React项目上，用户可以在其中上传文件，而我面临的问题是当我将文件上传到服务器并将该文件保存到名为“ uploads”的文件夹中时，该文件夹位于公共文件夹中，然后此过程完成后，页面刷新是因为应用程序正在监视所有更改并刷新页面
而且我知道可以通过编辑webpackdevserver.config文件来停止此操作，但是我不知道该怎么做。
webpackdevserver.config：
// @remove-on-eject-begin

'use strict';
const fs = require('fs');
const errorOverlayMiddleware = require('react-dev-utils/errorOverlayMiddleware');
const evalSourceMapMiddleware = require('react-dev-utils/evalSourceMapMiddleware');
const noopServiceWorkerMiddleware = require('react-dev-utils/noopServiceWorkerMiddleware');
const ignoredFiles = require('react-dev-utils/ignoredFiles');
const redirectServedpath = require('react-dev-utils/redirectServedpathMiddleware');
const paths = require('./paths');
const getHttpsConfig = require('./getHttpsConfig');
const host = process.env.HOST || '0.0.0.0';
const sockHost = process.env.WDS_SOCKET_HOST;
const sockPath = process.env.WDS_SOCKET_PATH; // default: '/sockjs-node'
const sockPort = process.env.WDS_SOCKET_PORT;
module.exports = function(proxy,allowedHost) {
return {
// WebpackDevServer 2.4.3 introduced a security fix that prevents remote
// websites from potentially accessing local content through DNS rebinding:
// https://github.com/webpack/webpack-dev-server/issues/887
// https://medium.com/webpack/webpack-dev-server-middleware-security-issues-1489d950874a
// However,it made several existing use cases such as development in cloud
// environment or subdomains in development significantly more complicated:
// https://github.com/facebook/create-react-app/issues/2271
// https://github.com/facebook/create-react-app/issues/2233
// While we're investigating better solutions,for Now we will take a
// compromise. Since our WDS configuration only serves files in the `public`
// folder we won't consider accessing them a vulnerability. However,if you
// use the `proxy` feature,it gets more dangerous because it can expose
// remote code execution vulnerabilities in backends like Django and Rails.
// So we will disable the host check normally,but enable it if you have
// specified the `proxy` setting. Finally,we let you override it if you
// really kNow what you're doing with a special environment variable.
disableHostCheck:
!proxy || process.env.DANGEROUSLY_disABLE_HOST_CHECK === 'true',// Enable gzip compression of generated files.
compress: true,// Silence WebpackDevServer's own logs since they're generally not useful.
// It will still show compile warnings and errors with this setting.
clientLogLevel: 'none',// By default WebpackDevServer serves physical files from current directory
// in addition to all the virtual build products that it serves from memory.
// This is confusing because those files won’t automatically be available in
// production build folder unless we copy them. However,copying the whole
// project directory is dangerous because we may expose sensitive files.
// Instead,we establish a convention that only files in `public` directory
// get served. Our build script will copy `public` into the `build` folder.
// In `index.html`,you can get URL of `public` folder with %PUBLIC_URL%:
// <link rel="icon" href="%PUBLIC_URL%/favicon.ico">
// In JavaScript code,you can access it with `process.env.PUBLIC_URL`.
// Note that we only recommend to use `public` folder as an escape hatch
// for files like `favicon.ico`,`manifest.json`,and libraries that are
// for some reason broken when imported through webpack. If you just want to
// use an image,put it in `src` and `import` it from JavaScript instead.
contentBase: paths.appPublic,contentBasePublicPath: paths.publicUrlOrPath,// By default files from `contentBase` will not trigger a page reload.
watchContentBase: true,// Enable hot reloading server. It will provide WDS_SOCKET_PATH endpoint
// for the WebpackDevServer client so it can learn when the files were
// updated. The WebpackDevServer client is included as an entry point
// in the webpack development configuration. Note that only changes
// to CSS are currently hot reloaded. JS changes will refresh the browser.
hot: true,// Use 'ws' instead of 'sockjs-node' on server since we're using native
// websockets in `webpackHotDevClient`.
transportMode: 'ws',// Prevent a WS client from getting injected as we're already including
// `webpackHotDevClient`.
injectClient: false,// Enable custom sockjs pathname for websocket connection to hot reloading server.
// Enable custom sockjs hostname,pathname and port for websocket connection
// to hot reloading server.
sockHost,sockPath,sockPort,// It is important to tell WebpackDevServer to use the same "publicPath" path as
// we specified in the webpack config. When homepage is '.',default to serving
// from the root.
// remove last slash so user can land on `/test` instead of `/test/`
publicPath: paths.publicUrlOrPath.slice(0,-1),// WebpackDevServer is noisy by default so we emit custom message instead
// by listening to the compiler events with `compiler.hooks[...].tap` calls above.
quiet: true,// Reportedly,this avoids cpu overload on some systems.
// https://github.com/facebook/create-react-app/issues/293
// src/node_modules is not ignored to support absolute imports
// https://github.com/facebook/create-react-app/issues/1065
watchOptions: {
ignored: ignoredFiles(paths.appSrc),},https: getHttpsConfig(),host,overlay: false,historyApiFallback: {
// Paths with dots should still use the history fallback.
// See https://github.com/facebook/create-react-app/issues/387.
disableDotRule: true,index: paths.publicUrlOrPath,public: allowedHost,// `proxy` is run between `before` and `after` `webpack-dev-server` hooks
proxy,before(app,server) {
// Keep `evalSourceMapMiddleware` and `errorOverlayMiddleware`
// middlewares before `redirectServedpath` otherwise will not have any effect
// This lets us fetch source contents from webpack for the error overlay
app.use(evalSourceMapMiddleware(server));
// This lets us open files from the runtime error overlay.
app.use(errorOverlayMiddleware());
if (fs.existsSync(paths.proxySetup)) {
// This registers user provided middleware for proxy reasons
require(paths.proxySetup)(app);
}
},after(app) {
// Redirect to `PUBLIC_URL` or `homepage` from `package.json` if url not match
app.use(redirectServedpath(paths.publicUrlOrPath));
// This service worker file is effectively a 'no-op' that will reset any
// prevIoUs service worker registered for the same host:port combination.
// We do this in development to avoid hitting the production cache if
// it used the same host and port.
// https://github.com/facebook/create-react-app/issues/2272#issuecomment-302832432
app.use(noopServiceWorkerMiddleware(paths.publicUrlOrPath));
},};
};
以及上传文件的存储位置：
structureAPP
所以我的问题是这样的：
如何编辑webpackdevserver.config文件以停止观看上传文件？
我一直在搜索此问题两天了，没有解决。
预先感谢。
解决方法
watchOptions: {
ignored: ignoredFiles(paths.appSrc),},这确实是列出忽略路径的地方，但是ignoredFiles(paths.appSrc)不是src文件夹。如果您看起来较高，则会看到ignoredFiles.js来自react-dev-utils模块。
const ignoredFiles = require('react-dev-utils/ignoredFiles');
使用react create app，默认的ignoredFiles.js返回node_modules文件夹，该文件夹通过避免观察者遍历所有模块来加快处理速度。现在可以将更多文件夹添加为watchOptions.ignored accepts an array，因此您可以直接在watchOptions中添加uploads路径。
watchOptions: {
ignored: [ignoredFiles(paths.appSrc),yourUploadPath],版权声明：本文内容由互联网用户自发贡献，该文观点与技术仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请发送邮件至 dio@foxmail.com 举报，一经查实，本站将立刻删除。
