React novice here. We have a situation in which we are going to be creating a sub-domain for every client that signs up for an app and then there will be a landing page for every client at <client_name>.ourwebsite.com.
The front-end for the website is going to be in React using React-Router v2.8, so when the user visits <client_name>.ourwebsite.com, the app needs to pick up the <client_name> and query the server for the data needed for landing page.
I am trying to set this up in the development environment by modifying the /etc/hosts file for every sub-domain name.
How do I get the React app to detect the <client_name> and get the data accordingly?
I hope this is a plain js question. You can get the hostname using window.location.host. This will return you xxx.ourwebsite.com as result in your case. Use this to get your subdoamin name and send it to api.

I have this website were we can create new questions. Whenever a new question is created a new url is generated I want google to crawl my website everytime a new question is added and display it in google.
I have my front end in react js and backend in express js.
My front end is hosted in firebase and backend in heroku.
Since I am using javascript and my urls are all dynamicly generated google does not crawl or index them.
Currently I am writing all dymaicly created urls into a file in my root folder in backend called sitemap.txt.
What should i do to achive this?
my sitmap link
https://ask-over.herokuapp.com/sitemap.txt
my react apps link
https://wixten.com
my express.js link
https://ask-over.herokuapp.com
i want to add
https://ask-over.herokuapp.com/sitemap.txt to google search console
In fact create-react-app is the wrong tool when SEO matters. Because:
there is only one HTML file
there is no content inside the single HTML file
heavy first load
etc, [search about reasons of using nextjs a good article
SPAs are the best for PWAs, admin panels, and stuffs like this.
But take a look at https://nextjs.org/docs/migrating/from-create-react-app. And my suggestion is to make some plans to fully migrate to Next.js.
Also, search about react SEO best practies and use the helpers and utilities like React Helmet.
create-react-app is not the way to go if you are going for a seo friendly website.
if it's behind a login screen you can go with create-react-app.
if the site is a blog or documentation site , I would suggest you migrate to nextjs or gatsby js or if it's a very small webpage go with raw html, css , js
It's not possible for Google or any other web crawler to crawl your SPA Websites. The best way to fix this is either to use Server Side Frameworks like Next.js or use pre-rendering and redirect crawlers to pre rendering server instead of main website.
You can checkout prerender.io, it has the open source version as well, you can run it on a seperate server and use one of the snippets/plugins for your web server (apache/nginx/others) to redirect requests to different upstream server.
I've been using it for one of my projects (e-commerce store) built on VueJs and it works like a charm.
To understand the basics, what it does is it'll load your website in a browser, and cache the rendered code in it's database/cache, and when any crawler visits your website they'll be redirected to cache which is the generated html page of your website, and crawlers will be able to read everything smoothly.
I currently have a website that uses SSR (using nextJS) to render the landing page in the root directory. However, I want the website to render my create-react-app application when the user is logged in. When the user is logged out, I want the website to show the landing page.
So my question is, is it possible to conditionally render using SSR when logged out, and use CSR when logged in? I'm just looking for general guidance on how to build the architecture that handles such event.
(The reason why I use SSR is for SEO reasons. My app doesn't need SEO so I want to use CSR instead. I also want to avoid using subdomains for now.)
It is possible with two options below:
(Recommended) Create a proxy server (just another Node server on top of your SSR and CSR servers), and implement the logic to proxy requests to either SSR or CSR in different cases. Or,
Create a custom Next server and route any logged-in requests to CSR. However, this option will sacrifice some major Next features.
I'm building a Shopify app with Next.js and I need to grab the query string so I can check in getServerSideProps the identity of the merchant (bear in mind that Cookies are not recommended for Shopify apps)
When visiting some apps I noticed some of them are getting the query string passed down from Shopify in each request.
This image shows how it should look on each request
This image shows how my app behaves
In this image you can see that when you hover the routes no query strings are present, meaning that are passed somehow by the parent app.
As of right now I'm using a Cookie to pass the shopOrigin but I feel like it's not necessary if somehow I'm able to get the query string in each request, also with the HMAC I will be able to verify that the requests are coming from Shopify.
Any calls to your App originating from Shopify properly provide the shop parameter when they make requests. In your own App calls to itself, you would also likely be using the shop name as a query string value.
Note that you are still able to validate your sessions internally using a cookie, you just don't do it via the third-party route, outside the iframe, like we used to. Shopify has plenty of documentation on how to properly authenticate, and construct Apps, check them out. They even give you a working Node App to play with, so you can ensure you get it right.
The solution was pretty straightforward.
Shopify provides a TitleBar AppBridge component that you can use to to handle the App's navigation. What it does is that on each route change it reloads the iframe and the hmac, shop, code and timestamp are coming in the request. It's a tad slower then client side routing but it works as expected.
In order to use it you just need to go to:
Partner's dashboard / Your App / Extensions / Embedded App (click Manage) / Navigation (click Configure) and add navigation links, then you just need to import TitleBar from app-bridge-react and put it in index.js
So I'm trying to deploy my first React application live. It is my portfolio webiste. Anyways, everything is working fine except for my routes. Locally, Everything works fine. However, now that I've deployed the website my routes do not work. When you click on any of the links it says the url cannot be found on the server, and it throws a 404 error.
The application is hosted by namecheap, and they said they cannot see anything wrong from their end. I just have no idea what could be wrong then as it all works find locally.
My website can be found at andrewschubert.website and the github repo for this can be found at https://github.com/theschubinator/my-portfolio If anyone has any ideas what I'm doing wrong I would greatly appreciate it!
By the way, it is a React Application. There is no database or API, just strictly front-end. The only links that are actually working are the ones that redirect you to an area outside of my application...like my blog on medium.
I can see that you've been using react-router lib for your routing. It is based on HTML5 history API, which is not supported by every host out there. If you are talking about your portfolio website and it's not so much of and issue where do you deploy it, try out some different hosts (e.g. surge is great for deploying static sites: https://surge.sh/).
React applications are single page. Routing in React means changing the components displayed when user requests a different url. You will need an api.
On every client request you return the same "index.html" which will display only one component. By creating a controller in your server you can map "/contact" to "index.html#contact" and your hashrouter can return the ContactUs component.
I have a backend using express to serve a static directory, to the path /, in which is contained a single page frontend. This backend also serves an API REST.
The frontend is built in React, and uses react-router to route the user from the different views of the web application.
If my react-router have two entries, let say /app and /config,
how can I redirect the client to that view of the application, if the user enters directly the URL in the web browser's address bar?
Right now, if I do that, Express gets the request and obviously returns a 404 message, as the single page is served to / path.
A simple way to resolve that is to always (even on 404s) send to user the index.html in your express route handlers.
See: https://stackoverflow.com/a/25499007/2624575
However, you need to take care of some things:
1) Your React Router code should start to handle 404s: https://stackoverflow.com/a/37491381/2624575
2) You need to handle correctly the path to your assets (icons, css, js, etc), otherwise you'll send the same index.html to those kind of resources (which will make your page render incorrectly)
3) Make sure that react-router is using browserHistory (the history that doesn't use hashes #), This way React will be able to render your routes correctly
Hope it helps!
