Editor User Guide
Working with Middleware
Middleware allows you to build complex extensions by setting up code that will run before your extension executes. This lets you perform security checks, load required data, or anything else you may need prepared before your extension is run. The Middleware panel allows you to add, edit, or delete middleware associated with your code.
The editor allows you to add middleware via NPM, URL, or with two special auth-based forms.
Once added, you can then re-arrange the order of and delete middleware.
