I have a current front-end only Angular 2 application using the Angular-CLI and NPM. I want visitors to be able to send me emails through the contact form.
For this I obviously need a back-end, express and node, in which I have no experience in using.
I need to intergrate express and node into my app but I dont know how to do this correctly.
I have found THIS similar question on SO but its not relevant to my situation.
Other tutorials only show how to scaffold a MEAN stack app not intergrate the backend after the front end has been built.
What I would like to know :
The best way to setup a project that is built using angular-cli to use a nodejs/express backend is to simple create an express project that serves up a directory. In your client project, if it has been created using the angular-cli, you should be able to just type in ng build
and it will compile everything into a dist
directory.
From there, you can create an express server that serves up that dist
directory like so:
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/index.html'));
});
The most simple server you could build would probably something like
var express = require('express')
var path = require('path');
var app = express()
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/index.html'));
});
app.listen(3000, function () {
console.log('Example app listening on port 3000!')
});
This will intercept all routes and redirect them to the index.html
file in the dist/
folder that was created.
For more information on how to set this up and some more advanced settings, check out these links:
Just think about the dist/
folder as static files that will be served over an express server, and because routing and everything is handled through angular, you'll be set.
