Deployment of Angular 2 Application on Heroku is very simple task. We can deploy Angular 2 app on Heroku by many ways like Heroku CLI and Github.
Before deployement process we need to sure that our application should be in a production deployment mode.
Suppose we have created the dist folder for production deployment. If still you have not created the
dist or deployment folder the we can create it by following cammands.
If you are using webpack then ng build --prod is the command for create the build files or dist folder.
We need to deploy only these build files to run our angular app with any backend server like express, hapi and other
web servers.
If your application structure is like below format after create the build files or dist folder.
/e2e /dist /node_modules /src .angular-cli .editorconfig karma.conf.js package.json protractor.conf.js README.md tsconfig.json tslint.json
To deploy the angular 2 application we need a web server like express js.
So we need to install a express js framework to deploy the angular app.
Create a package.json and server.js file to with express js framework.
server.js
const express = require('express');
const app = express();
const path = require('path');
app.use(express.static(__dirname + '/dist'));
app.listen(process.env.PORT || 8080);
app.get('/*', function(req, res){
res.sendFile(path.join(__dirname + '/dist/index.html'));
});
console.log('Server listening');
Now upload all these files on Github or use Heroku CLI to deploy directly. Here we will use git to upload all the files on github
/dist package.json server.js
Then we can deploy our angular app with heroku. We need Heroku account and need to create our app with Heroku.
