Express middleware cannot trap errors thrown by async/await, but why?

由 和自甴很熟 提交于 2019-12-10 14:45:08
问题 These two middleware functions behave differently and I cannot figure out why: Here, the error will get trapped by try/catch: router.get('/force_async_error/0', async function (req, res, next) { try{ await Promise.reject(new Error('my zoom 0')); } catch(err){ next(err); } }); But here, the error will not get trapped by try/catch: router.get('/force_async_error/1', async function (req, res, next) { await Promise.reject(new Error('my zoom 1')); }); I thought Express wrapped all middleware

Node Express 4 middleware after routes

由 元气小坏坏 提交于 2019-12-05 08:40:12
问题 Following the upgrade to Express 4, and the removal of app.router, I'm struggling to get middleware to execute after routes execute. e.g. the following code correctly responds with "hello", but never calls the configured middleware var express = require( "express" )(); express.get( "/", function( req, res ) { res.send( "hello" ); } ); express.use( function( req, res, next ) { console.log( "world" ); next(); } ); express.listen( 8888 ); CLARIFICATION: the following code shows "before" on the

由 时光毁灭记忆、已成空白 提交于 2019-12-03 14:11:06
I try to use csurf on just a few routes in my express app. that's the approach: var express = require('express'); var session = require('express-session'); var csrf = require('csurf'); // some more stuff var csrfExclusion = ['/myApi','/unsecure']; var app = express(); var conditionalCSRF = function (req, res, next) { if (csrfExclusion.indexOf(req.path) !== -1){ next(); } else{ csrf(); } }); app.use(conditionalCSRF); even tried: var conditionalCSRF = function (req, res, next) { if (csrfExclusion.indexOf(req.path) !== -1){ next(); } else{ csrf(req, res, next); next(); } }); and var

Elasticsearch show all results using scroll in node js

由 北战南征 提交于 2019-12-02 23:57:58
I am basically trying to show all records of an index type. Now, if you use match_all() in query elasticsearch shows 10 results by default. One can show all results using scroll. I am trying to implement scroll api, but can't get it to work. It is showing only 10 results, my code: module.exports.searchAll = function (searchData, callback) { client.search({ index: 'test', type: 'records', scroll: '10s', //search_type: 'scan', //if I use search_type then it requires size otherwise it shows 0 result body: { query: { "match_all": {} } } }, function (err, resp) { client.scroll({ scrollId: resp.

Express 4, NodeJS, AngularJS routing

由 让人想犯罪 __ 提交于 2019-11-30 09:20:52
问题 I am using Express 4 to host my AngularJS app on my backend, with Nginx as my frontend server. However html5 mode does not seem to work, as I will get a Cannot /GET error when I try to enter the page link (e.g. http://localhost/login ) via the browser. Is there any routing configuration I need to do for my Express/Nginx? Here's my config code: Express 4: var express = require('express'), app = express(), server = require('http').Server(app), bodyParser = require('body-parser'), db = require('

Express 4 + pm2 watch not working

由 依然范特西╮ 提交于 2019-11-27 18:01:45
I'm running pm2 with this: pm2 start bin/www --watch ../ Problem is that when I update app.js in the root folder, it doesn't seem to be autorestarting node. Any ideas? Figured out a solution: //processes.json: { "apps" : [{ "name" : "someExpress4App", "script" : "bin/www", "watch" : "../", "log_date_format" : "YYYY-MM-DD HH:mm Z", }] } Put that on the root of your project, then run your pm2 as so: pm2 start processes.json 来源： https://stackoverflow.com/questions/27882759/express-4-pm2-watch-not-working
