So there are only so many times that you wish to come across the dreaded CORS error before you start thinking that there must be a better way. You come across cors-anywhere and think, “This is it!!! But how do do I deploy? Why aren’t the steps just out there?”
Well now thanks to a fed up novice web developer. You too can solve these errors in a snap with your own private cors-anywhere deployment.
So if you do not have the following I would recommend installing them before you get started.
The next thing that you are going to need to do is install heroku via npm. Run:
npm install heroku.
Go ahead and either fork and clone or just clone the cors-anywhere. Once you have have the repo cloned on your machine you can deploy to Heroku in 2 steps. First open up your cli and go to the cloned directory then run:
git push heroku master
If this is your first time working with Heroku you are going to need to sign up for a free account and then sign-in.
If deployed correctly you should be able to go to the Heroku dashboard and find your cors-anywhere application
Once you have deployed and have it up and running you should be able to get to the options by going to the application > settings and then scroll down to
config vars and click
reveal config vars.
Right now there are 2 different variables that I have set up for my project:
- RATELIMIT - This sets up the amount of default requests can be made it take 3 different variables. Number of requests, reset of ratelimit, and a space separated list of exempt sites.
- WHITELIST - This is the master list of URL’s that you are allowed to use this application.
