Node.js服务器不释放内存
运行节点/快递服务器时遇到问题。 服务器运行良好，但随着时间的推移使用大量的内存。 它开始于约70mb的内存使用量。 但是，每个请求需要大约2mb。 很快它就达到了1.5GB的标准并冻结。 它也不会随着时间的推移释放任何内存。 我的server.js中是否有任何一般错误：
import 'babel/polyfill'; import _ from 'lodash'; import fs from 'fs'; import path from 'path'; import express from 'express'; import ReactDOM from 'react-dom/server'; import router from './router'; import Translator from './core/Translator.js'; import cookieParser from 'cookie-parser'; import StoreContainer from './utils/redux.js'; import { combineReducers } from 'redux'; import reducers from './reducers'; import {setAuthToken, removeAuthToken} from './utils/api'; import i18nLocation from './utils/i18nLocation.js'; import {api, setLangHeader, setProtocol} from './utils/api'; import {clearActiveApartment} from './actions/activeApartment.js'; import {clearCityInfo} from './actions/city.js'; import {setDevice} from './actions/appData.js'; import MobileDetect from 'mobile-detect'; import StaticConfiguration from './constants/StaticConfiguration.js'; import compression from 'compression'; const server = global.server = express(); server.set('port', (process.env.PORT || 5000)); server.use(cookieParser()); server.use(compression()); server.use(express.static(path.join(__dirname, 'public'))); // The top-level React component + HTML template for it const templateFile = path.join(__dirname, 'templates/index.html'); const template = _.template(fs.readFileSync(templateFile, 'utf8')); server.get(/^[^.]+$/, async (req, res, next) => { setProtocol(req.protocol); StoreContainer.emptyStore(); let store = StoreContainer.store; let data = _.pick(req, ['baseUrl', 'ip', 'hostname', 'originalUrl', 'path', 'protocol', 'headers']); api.saveRequest({ data: data }).then(response => { }, _.noop); try { let statusCode = 200; let data = { title: '', description: '', css: '', body: '', country: '', city: '', lonlat: '', image: '/images/test.jpg', fbId: StaticConfiguration.fbKey, analytics: StaticConfiguration.analyticsKey}; const css = []; let lang = Translator.resolveLangForRequest(req); lang = 'de'; // TODO: remove this line to allow other langs Translator.initialize({descriptor: lang}); setLangHeader(lang); if (req.cookies && req.cookies['wg-token']) { setAuthToken(req.cookies['wg-token']); } const context = { onInsertCss: value => css.push(value), onSetTitle: value => data.title = value, onSetMeta: (key, value) => data[key] = value, onPageNotFound: () => statusCode = 404 }; await router.dispatch({ path: req.path, context }, (state, component) => { // redirect to another page if (state.redirect) { res.redirect(state.redirect); } data.body = ReactDOM.renderToString(component); data.css = css.join(''); data.langFile = Translator.resolveLangFile(lang, req); data.initialState = JSON.stringify(store.getState()); data.langCode = lang; }); removeAuthToken(); let html = template(data); res.status(statusCode).send(html); } catch (err) { next(err); } }); // // Launch the server // ----------------------------------------------------------------------------- server.listen(server.get('port'), () => { if (process.send) { process.send('online'); } else { console.log('The server is running at http://localhost:' + server.get('port')); } }); res.direct可能有问题。 它应该可能被返回，以便调度函数不会继续运行data.body = ， data.css =等。检查请求是否已被redirect也可能有所帮助，以便在调用之后的代码await router.dispatch()如果您已经redirect， await router.dispatch()不会运行。
例如：
let redirected = false await router.dispatch({ path: req.path, context }, (state, component) => { // redirect to another page if (state.redirect) { redirected = true; res.redirect(state.redirect); return; // stop data.body, data.css, etc from getting set } data.body = ReactDOM.renderToString(component); data.css = css.join(''); data.langFile = Translator.resolveLangFile(lang, req); data.initialState = JSON.stringify(store.getState()); data.langCode = lang; }); if (redirected) return; // already redirected, don't send html
