20:33 Router with SSR
Server-side rendering is pretty helpful if the client is in a slow network connection or the application needs to have good search engine optimization (SSO). By using angular universal we enable our application to be rendered from the server-side so that the initial loading will be faster and the application will have good SSO.

Thanks for watching...
Clear explanation!
So just to test things out after build:ssr I did this. 1) I edited dist/server/main.ts I changed 'home works!' to 'home-server works!'. 2) I edited dist/browser/main.***.ts I changed 'home works!' to 'home-browser works!'. Then I ran serve:ssr. I set the browser to localhost:4000. Pressing the home button shows "home-browser works'. This indicates to me that serve:ssr runs the dist/browser version of the code not the dist/server version of the code as one would expect. I did some research and found out that main.ts in server quickly redirects to the browser main.***.ts. This gives one the feeling that SEO will work in theory but in practice search engine crawlers do not use Javascript. What really needs to be done is npm run prerender. It creates a different structure in dist than this video proposes. I performed the above checks with prerender and tested by turning javascript off in chrome. I saw home-server works on the browser. So that proves it works!
Really made SSR simple. Thank you.
Not able to it. When i am running the command - ng add @nguniversal/express-engine
It says Packages installation failed giving warning as
1. Unable to find compatible package. Using 'latest' tag.
2. Package has unmet peer dependencies. Adding the package may not succeed.

@@FunOfHeuristic No problem bro. I have searched in youtube i got basic usage of onPush change detection strategy. Thats why asked you
@@FunOfHeuristic i dont want to serve the app and see the page source bcoz its take too much time in loading i just want to upload the build and see the source code of the page for seo purpose.How to do it sir.Please resolve my issue
Hey Hi, I have a query regarding angular universal, is there a way to use gsap (greensock) or jquery animation in my project after angular universal rendering..
When you make a component and use it as a web page, does it's HTML also gets rendered if you apply SSR?
great tuto thx
how to build then? with ng build?
Can we run angular universal SSR for only specific routes?
In Firebase it works like this:
In Your firebase.json you can create several rewrites. Example:
"rewrites": [
{
"source": "/",
"destination": "/index.html"
},
{
"source": "**",
"function": "ssr"
}
]
}
In this case all Routes except the home route are redirected to the Function for SSR
Thank you!
im getting issues on using localstorage and window (), is there a global fix for these?
You can use OpaqueToken from angular to use the functionality, because window is not available in chrome.

Thanks
sir i'm completely setup angular universal in my project. But when i'm uploading the build on the server then not get the source code of the page. Only get the source code on serve the app.
I will make a video on deployment of universal soon
Thank a lot!!!
Hi,
I am exploring angular universal and I have one question, will it be possible to use angular universal for entire app?
Yes it should be for entire app, normal app is client side rendering and universal is server side rendering
Really lots of talk for nothing ? i am actually looking an example , in past i have issue with dynamic html render, say a complete page coming from database including javascript in it , how can i render that ?
Hi, I started creating just a front end app using universal but i have to access 3rd party API which is giving cors error. I created a mock node.js server to bypass cors for development purpose but what to do after deployment ? Thanks.
Cors error can be completely remove if server allow your url. But you can use no-cors(in fetch call) to disable.
@@FunOfHeuristic Hi, can you help me out with an issue in which we have to make a third party api call on load itself which i am doing it in server.ts and then render the index.html with json. I am not able to understand how to receive api response on frontend. Thanks
You've made it so easy, thank you for your efforts!
how can i use both ssr and csr?
Hi i have integrated universal to my existing project and hosted on firebase. Also i am using dynamic meta tags when changing router. I can see og meta tags in view souce. When sharing to fb some urls crawling and show fb card. But some url not crawling. Please let me know the reason.
Hello, did you succeed to make it work. I'm in the same situation. How did you do the migration from CSR to SSR. You keep both ?
@@tedkossoko3747 you need to prerender all routes in the npm build all
@@DeeClassroom What do you mean by pre render ?Thanks

Does SEO work just as well with dist/browser (CSR) as dist/server (SSR)? If I want my website to be SEO friendly does it need to be run on a server using node?
Short answer is yes, if you want to cover all search engines then you should reder your html in server side for Angular
hello sir i have successfully installed ssr in my project.I just need a little bit of ur help. When i serve the ssr build then it show's only static data on the place of dynamic data it show like this . What i am doing wrong.Please help me to solve this isse. Thanks in advance
Dynamic data you mean data from api or data from your ts file.
@@FunOfHeuristic data from getting https apis is not showing in view page source.On place of it only show bindings.
It should work, any specific error you are getting, and how you are trying to render the object or array
@@FunOfHeuristic not getting any kind of error sir and as per need i render object as well as array on the place of dynamic content it show's nothing..cant understand how to get out of it.
My git repo is github.com/iamsanjaychouhan/ssr
if u have any idea then plz help me sir
thanks for ur reply
I m asking you some question
my project Error: You must pass in a NgModule or NgModuleFactory to be bootstrapped
how to implement it in already running project?
The process is same, but you have to test everything properly as all the things are not supported by universal.
I want to deploy the build with my pythonanywhere server. Where node server is not available.
Is it possible to deploy ssr build without your node / express .
No, as it works with express, you can deploy the normal angular application.
@@FunOfHeuristic I want to share pages on social networks so title and meta should be dynamic.
Is there any other way to achieve that instead universal ?
For title you can use Title service provided by angular to change title dynamically, I need to check about meta tag, if I will find something I will reply here.
@@FunOfHeuristic thanks for quick response.
I am using titleservice and meta service now but without universal it is not working.
Thanks again for your support. 🙂🙏🏽
is it possible to make only one module (ssr)
No, the whole application need to be render in server, there will be ways but it's not good practice.
@@FunOfHeuristic will you be able to suggest one way for me please?
Great video man, can you make one showing how to configure and deploy with docker?
Yes please! Is the video up yet?!
@@adigunademola8360 no. Do you find an example. I'm working on it to push on Docker.
Nice Video Bro, I have some issue, as i am using API calls but unable to get the API Data in "View Source" it shows in Developer tools, please let me know is there any way to get the API data in View Source
Hi, do you mean you are not able to bind data to the view?
@@FunOfHeuristic no,
Data binding and every thing ok, but the data in the view is unable to view in view source, static content is displayed but dynamic content not visible in view source
@@FunOfHeuristic Yeah... I'm Facing this error too "NetworkError
at XMLHttpRequest.send" means Angular universal is not able to get data from api on the server whether it is a relative url or absolute url...!!!
I will make a video on the same.
@@FunOfHeuristic Got it Done Bro!! Following this guide github.com/angular/universal/blob/master/docs/transfer-http.md
And Making Absolute Url Calls i.e- "ww..." .
If you'll be making the video for the same please do suggest the best way to use same server api... Thanks!!😇
