Middleware

A middleware is a module with a default function that:

• takes as input a context object with the HTTP request
• and returned:
  • a Web Api HTTP Response
  • or a page

Usage

• CMS integration that returns a page
• Request Context enhancement such as adding a user via User Authentication

Registration

You can register your middleware:

• automatically by storing it in the middlewares directory (src/middlewares by default)
• in the middelwares node of the configuration file

Example:

json⎘ Copy
{
  "middlewares": [
    {
      "importPath": "./cms/my-cms-middleware.js",
      "props": {
        "uri": "",
        "timeout": 1
      }
    }
  ]
}

• They are executed in natural order.
• The import path may be relative to the root directory

How to list the middlewares

You can check them with the cli

bash⎘ Copy
interact config --filter="middlewares"
