How do you deploy Angular apps

Question

How do you deploy Angular apps once they reach the production phase     All the guides I ve seen so far  even on angular io  are counting on a lite-server for serving and browserSync to reflect changes - but when you finish with development  how can you publish the app     Do I import all the compiled  js files on the index html page or do I minify them using gulp  Will they work  Do I need SystemJS at all in the production version

You are actually here touching two questions in one.

The first one is How to host your application?.
And as @toskv mentioned its really too broad question to be answered and depends on numerous different things.

The second one is How do you prepare the deployment version of the application?.
You have several options here:

Deploy as it is. Just that - no minification, concatenation, name mangling, etc. Transpile all your ts project copy all your resulting js/css/... sources + dependencies to the hosting server and you are good to go.
Deploy using special bundling tools, like webpack or systemjs builder.
They come with all the possibilities that are lacking in #1.
You can pack all your app code into just a couple of js/css/... files that you reference in your HTML. systemjs builder even allows you to get rid of the need to include systemjs as part of your deployment package.
You can use ng deploy as of Angular 8 to deploy your app from your CLI. ng deploy will need to be used in conjunction with your platform of choice (such as @angular/fire). You can check the official docs to see what works best for you here

Yes you will most likely need to deploy systemjs and bunch of other external libraries as part of your package. And yes you will be able to bundle them into just couple of js files you reference from your HTML page.

You do not have to reference all your compiled js files from the page though - systemjs as a module loader will take care of that.

I know it sounds muddy - to help get you started with the #2 here are two really good sample applications:

SystemJS builder: angular2 seed

WebPack: angular2 webpack starter

In order to deploy your Angular2 app to a production server  first and foremost  ensure your app runs locally on your machine   Angular2 app can also be deployed as a node app   So  create a node entry point file server js app js  my example uses express   var express   require  express        path   require  path        fs   require  fs     var app   express    var staticRoot     dirname         app set  port    process env PORT    3000     app use express static staticRoot     app use function req  res  next           if the request is not html then move along     var accept   req accepts  html    json    xml        if accept      html            return next                  if the request has a     assume that it s for a file  move along     var ext   path extname req path       if  ext                  return next               fs createReadStream staticRoot    index html   pipe res          app listen app get  port    function         console log  app running on port   app get  port           Also add express as a dependency in your package json file   Then deploy it on your preferred environment   I have put together a small blog for deployment on IIS  follow link

Angular 2 Deployment in Github Pages  Testing Deployment of Angular2 Webpack in ghpages  First get all the relevant files from the dist folder of your application  for me it was the     css files in the assets folder    main bundle js    polyfills bundle js    vendor bundle js  Then push this files in the repo which you have created   1 -- If you want the application to run on the root directory - create a special repo with the name  yourgithubusername  github io and push these files in the master branch  2 -- Where as if you want to create these page in the sub directory or in a different branch other than than the root  create a branch gh-pages and push these files in that branch   In both the cases the way we access these deployed pages will be different   For the First case it will be https    yourgithubusername  github io and for the second case it will be  yourgithubusername  github io  Repo name    If suppose you want to deploy it using the second case make sure to change the base url of the index html file in the dist as all the route mappings depend on the path you give and it should be set to   branchname    Link to this page  https   rahulrsingh09 github io Deployment  Git Repo   https   github com rahulrsingh09 Deployment

I would say a lot of people with Web experience prior to angular  are use to deploying their web artifacts inside a war  i e  jquery and html inside a Java Spring project   I ended up doing this to get around CORS issue  after attempting to keep my angular and REST projects separate   My solution was to move all angular  4  contents  generated with CLI  from my-app to MyJavaApplication angular  Then I modifed my Maven build to use maven-resources-plugin to move the contents from  angular dist to the root of my distribution  i e   project build directory  MyJavaApplication   Angular loads resources from root of the war by default   When I started to add routing to my angular project  I further modifed maven build to copy index html from  dist to WEB-INF app  And  added a Java controller that redirects all server side rest calls to index

Simple answer   Use the Angular CLI and issue the   ng build    command in the root directory of your project   The site will be created in the dist directory and you can deploy that to any web server   This will build for test  if you have production settings in your app you should use  ng build --prod   This will build the project in the dist directory and this can be pushed to the server   Much has happened since I first posted this answer   The CLI is finally at a 1 0 0 so following this guide go upgrade your project should happen before you try to build   https   github com angular angular-cli wiki stories-rc-update

As of 2017 the best way is to use angular-cli  v1 4 4  for your angular project   ng build --prod --env prod --aot --build-optimizer --output-hashing none   You needn t add --aot explicitly as its turned on by default with --prod And the use of --output-hashing is as per your personal preference regarding cache bursting   You could explicitly add CDN support by adding     --deploy-url  https    lt your-cdn-key gt  cloudfront net     if you plan to use CDN for hosting which is considerably fast

If You test app like me on localhost or You will have some problems with blank white page i use this   ng build --prod --build-optimizer --base-href  http   127 0 0 1 my-app     Explanation   ng build   Build app but in code there is many spaces  tabs and other stuff what makes code able be read by human  For server it isnt important how code looks  This is why i use   ng build --prod --build-optimizer    This make code out for production and reduce size  --build-optimizer  allow to reduce more code    So at end i add --base-href  http   127 0 0 1 my-app   to show application where is  main frame   in simple words   With it You can have even multiple angular apps in any folder

With Angular CLI  you can use the following command   ng build --prod   It generates a dist folder with all you need to deploy the application   If you have no practice with web servers  I recommend you to use Angular to Cloud  You just need to compress the dist folder as zip file and upload it in the platform

For a quick and cheap way to host an angular app  I have been using the Firbase hosting  It s free on the first tier and very easy to deploy new versions using the Firebase CLI  This article here explains the necessary steps to deploy your production angular 2 app to Firebase  https   medium com codingthesmartway-com-blog hosting-angular-2-applications-on-firebase-f194688c978d  In short  you run ng build --prod which creates a dist folder in the package and that s the folder that gets deployed to Firebase Hosting

With the Angular CLI it s easy  An example for Heroku    Create a Heroku account and install the CLI Move the angular-cli dep to the dependencies in package json  so that it gets installed when you push to Heroku  Add a postinstall script that will run ng build when the code gets pushed to Heroku  Also add a start command for a Node server that will be created in the following step  This will place the static files for the app in a dist directory on the server and start the app afterward       scripts                 start    node server js      postinstall    ng build --aot -prod       Create an Express server to serve the app         server js const express   require  express    const app   express       Run the app by serving the static files    in the dist directory app use express static   dirname     dist        Start the app by listening on the default    Heroku port app listen process env PORT    8080      Create a Heroku remote and push to depoy the app      heroku create git add   git commit -m  first deploy  git push heroku master   Here s a quick writeup I did that has more detail  including how to force requests to use HTTPS and how to handle PathLocationStrategy

You get the smallest and quickest loading production bundle by compiling with the Ahead of Time compiler  and tree-shake minify with rollup as shown in the angular AOT cookbook here  https   angular io docs ts latest cookbook aot-compiler html   This is also available with the Angular-CLI as said in previous answers  but if you haven t made your app using the CLI you should follow the cookbook   I also have a working example with materials and SVG charts  backed by Angular2  that it includes a bundle created with the AOT cookbook  You also find all the config and scripts needed to create the bundle  Check it out here  https   github com fintechneo angular2-templates   I made a quick video demonstrating the difference between number of files and size of an AoT compiled build vs a development environment  It shows the project from the github repository above  You can see it here  https   youtu be ZoZDCgQwnmQ
