I am following a tutorial (https://levelup.gitconnected.com/simple-application-with-angular-6-node-js-express-2873304fff0f) on creating an app with Angula CLI, Node.js and Express. I use a proxy to start the app, the file defining the proxy looks like this:
{
"/api/*": {
"target": "http://localhost:3000",
"secure": false,
"logLevel": "debug",
"changeOrigin": true
}
}
The command I use to start the app is this one:
ng serve --proxy-config proxy.conf.json
The tutorial said that:
All requests made to /api/... from within our application will be forwarded to http://localhost:3000/api/...
To be honest, I don't really know how it is supposed to work, because when I launch the app, I still use the URL: http://localhost:4200/ .
But I didn't have a problem until now. I just created a route with Express.js at the Endpoint /api/v1/generate_uid .
But the problem is when I go to http://localhost:4200/api/v1/generate_uid it shows this message:
Error occured while trying to proxy to: localhost:4200/api/v1/generate_uid .
The following is the message I get in the console:
[HPM] Error occurred while trying to proxy request /api/v1/generate_uid from localhost:4200 to http://localhost:3000 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
And when I go to http://localhost:3000 it always says that the connection has failed.
For further references, Here are the app.js
of my express API and generate_uid.js
which defines the route:
app.js
var express = require('express');
var uid = require('uid-safe');
var router = express.Router();
router.get('/', function(req, res, next) {
var strUid = uid.sync(18);
res.json({guid: strUid});
});
module.exports = router;
generate_uid.js
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var users = require('./routes/users');
var generate_uid = require('./routes/generate_uid');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser())
app.use('/api/v1/users', users);
app.use('/api/v1/generate_uid', generate_uid);
module.exports = app;
So I really don't know what the solution is. Thanks in advance for your answers !!
