There's a feature in Angular Universal that allows you to pre-render pages at build-time. Can this be used to pre-render all your pages and run Angular Universal without a server?
Once html pages have been pre-rendered using angular universal (using nodejs server or asp.net core server), you can use any CDN to serve the pre-generated html.
See https://universal.angular.io/overview/
Edit: have a look at the starer kit
https://github.com/angular/universal-starter
Basically, you can reuse the prerender.js file which will write the rendered html files (for specified static routes) to the dist/browser folder, or wherever you want to. This is that folder that you deploy to a static host after
Well, you're always going to need to have a server somewhere in the equation: the only question is how much you have to set it up yourself versus how much can the current crop of tools and technologies do it for you.
In this talk from Node Summit Steven Fluin from Google talks about Firebase at the end. Pay attention to the bit about 'cloud functions' (at about 20 mins). Your Angular app will be rendered on the server using Firebase cloud functions. When a user interacts with your app, some JS is run to figure out what to send down (from the Firebase server) to the user. "You don't need to set up a server at all; everything is running in Firebase."
I haven't used Firebase myself - I'm using Angular Universal, which has a Node.js server as you know - but this sounds very nice. I found setting up Angular Universal really tricky (but got there in the end).

I am new to blockchain development and to tendermint as well.
I already have a blockchain running locally.
Using this command starport scaffold vue I could mount a local web application. Inspecting a bit I could replicate some network requests (localhost) and I can get the ballance of current wallet (hard-coded on the request), get the current wallet from the localstorage. I'm struggling on authentication (mnemonic, wallet name and password).
However I also would like to costumize it according to my needs and I thought I could start a web application from scratch. I can see that the generated web project is importing this project https://github.com/tendermint/vue which is making a lot of "magic behind the scenes" and importing UI elements as well and I would like to have my own elements.
I don't want to re-invent the wheel and I can make some imports to help me on connection to wallet, validate authentication (mnemonic, wallet name and password), create wallet and so on.
I am trying to build a web application to connect to wallet, make transations.... but I would like to control the styles and the connections (and if possible using reactjs instead of vuejs, otherwise I dont mind learn vuejs as well).
Is this possible or reasonable? Where I can find good documentation or tutorial to guide me on customize a web application using tendermint. Honestly I searched but I am kind of lost.
Thanks
UPDATE: I found good examples and here and here. It helped me to validate mnemonics and make transactions, with my stack tech.
Because Starport generates both plain Javascript and VUE controllers, you have few options:
Create your own site re-using VUE components
Take plain JS part and build a website using whatever technology you like
Use a plain JS client for standard cosmos modules you can find on GitHub
Use Protobuf generator to generate light client code yourself
If you only need wallet functionality, #2 and #3 may work best for you because the bank module is stable and hasn't changed much in a long time.
You can find plain JS file for bank in your project:
vue/src/store/generated/cosmos/cosmos-sdk/cosmos.bank.v1beta1/module/index.ts

I'm building a Vue app that works as a SPA that gets rendered by my Express backend.
In this Vue app I'm using environment variables. One of these variables is an API key to an external API service.
Obviously I don't want to show the whole world my API key, however after I run the build command it includes all the env variables in the Javascript files, which I believe makes it accessible to anyone.
What would be the right way to go here? Should I make a route in my Express backend that handels requests to this external API, so that I can safely store my API key on the server side?
Or is there a way to make my Vue app autonomously send requests to the external API without having to show the API key?
I'm using Vue 2 by the way.
Yes you should make a backend that will interact with API using your key instead of the front end doing that no matter which version of VueJs your are using
VueJS is front end javascript, which mean users can see the code even minified on their browser
is what you are looking for
Your could use Nuxt, which is an SSR solution to build your app before shipping it to production. During the build, you can get use some sensible stuff since it will run NodeJS and will be on the server only. That way, you could for example fetch some variables and let's say get the content of some blog articles. Then, it will be available on the frontend with the end result only and all your variables safe since they will be used only on the server build.
Other solution is to use your backend as a middleware to do exactly the same process of using something sensitive and just fetch the end result.
Also, serverless functions like on Firebase or Azure are great + cheap for this purpose.
I came across vuexpress, vuepress and vue-server-renderer. To me these are looking somewhere similer which I guess are not. I am not frontend developer so not able to understand exact difference and use of these three modules.
Their official sites are saying
https://github.com/vuexpress/vuexpress
vuexpress: Vue + Express.js = VueXpress / A server side rendering
engine for Express.js. Use .vue files as your express.js templates.
https://vuepress.vuejs.org/
VuePress: Vue-powered Static Site Generator
https://ssr.vuejs.org/
vue-server-renderer: server-rendered Single-Page Applications using
Node.js as the server.
vuepress and vue-server-renderer are official library from Vue.js
So what exactly are differences and use of these three modules?
The idea with Vue (from the perspective of your question) is that you create a single-page application.
vuexpress is a rendering engine you can use in an Express application if you want to use the Vue syntax to implement your Express views, i.e. you implement a dynamic website and use the Vue syntax.
vuepress is about building a single-page application in Vue that also prerenders each page (and some other goodies, such as using markdown) to improve initial page load and facilitate for search engines. It is primarily used for websites with static content, such as documentation.
The point with a Vue application is to run it on the client (in the web browser). With vue-server-renderer you can run it on the server to obtain the HTML code the web browser would render if it would run in the web browser, and send it to the web browser, so the web browser doesn't need to run your Vue application, but receives the HTML it would display instead. Why? To improve initial page load and facilitate for search engines. I imagine vuepress makes use of vue-server-renderer under the hood.
I have this reactjs webapp - http://52.26.51.120/
It loads a single page and then you can click links to dynamically load other boards on the same page... such as 52.26.51.120/#/b, 52.26.51.120/#/g
Now the thing is, I want each of these to be an individual page, for the purpose of seo. I want you to be able to google "my-site.com g", and you will see the result 52.26.51.120/#/g. This obviously cant work if you are using reactjs and it is all on one page. Google will only render and cache that main page (can it even render that page? does google execute javascript?)
Even more specifically, id want something like my-site.com/g/1234 to load a thread. There could be a thousand threads every day, so im not sure how to handle that.
Are there any solutions to this? to allow react to possibly serve up static pages as html so that they can be cached on google? I am using expressjs and webpack as my server right now, and all the code is executed in jsx files.
Thanks
You can use Prerender.io service. In a nutshell you will need to connect your server app or web server with prerender service and do little setup (see documentation). After that search engines and crawlers will be served with a static (prerendered) content while users will get classic React.js (or any other single page) app.
There is a hosted service with free tier or open source version
I suspect you could do some smart configuration with nginx and it could convert a url of domain/board to a redirection of domain/#/board when detecting the user-agent as a bot instead of a typical user.
I'm using SBT SDK on a XPage.
After mastering a few traps at the beginning it works fine.
Livenames are properly displayed.
But now a got another problem.
If you click on a available person, a context menu is displayed, where you can choose 'CHAT' or 'VCARD'.
If I click on CHAT a URL like this ist called:
http://localhost:59449/stwebapi/loggedin?jsonp=stproxy.connect.callback.setAvailable&wait=true&time=1407834968761&fqdn=sametime.lotus.com
I found out that you have to install Sametime Connect Client locally at every computer, because it is providing a small webserver at port 59449.
That's impossible because I want to use Sametime on a public website.
I'm pretty sure that there is another way.
Somebody an idea?
thanks

#user2776693 - There are two ways:
1 - using the Sametime Local Web API
The local web api uses a configurable port (the default is mentioned above), to communicate back and forth from a web site which embeds or calls the configurable port using jsonp, meaning the javascript of the site wraps the sametime calls.
2 - using the Sametime Web Chat/Web Proxy
It means that the Sametime Web Chat is embedded as JavaScript on the page, and loaded using the appropriate JS libraries, and can have some pretty advanced features. There is a demo site off of greenhouse.lotus.com, and you can sign up for an account on that site.
you can download the sdk, and find many examples of using the local web api and web chat.
