Let's say I have a react application hosted at example.com. Now, I already have a very simple html/js website that I want to display at example.com/example. I can easily do this if I rewrite the website in react, but I don't want to do that because the html/js website is so simple and it would be unnecessary to be written in react.
Is there any way I can directly put and link this html/js website with the rest of my project?
When you create React app with create-react-app you have the following filesystem structure:
my-app/
README.md
node_modules/
package.json
public/
index.html
custom-page.html <-- Create custom page
favicon.ico
src/
App.css
App.js
App.test.js
index.css
index.js
logo.svg
https://facebook.github.io/create-react-app/docs/folder-structure
So, you can just create any static pages in /public directory and reference them. All the resources in /public directory will be available in the root of your website.
For example, custom-page.html will be accessible by http://localhost:3000/custom-page.html.
