node package manager



A middleware to perform dynamic text substitution on served resources. Useful to automatically replace URLs within resources depending on whether a server is running in dev or production mode.


  1. Include connect-substitute in a node module.
    const substitute = require("connect-substitute");
  1. Add a middleware by calling the setup function.
      from: "",
      to: ""

from is the text to be changed. to is what you want to change from to.

The substitution middleware must be added before other middlewares that serve resources, including static middleware.


This is an extremely thin wrapper around Lloyd Hilaiel's connect-postprocess. He is the brains behind it, I only added a slightly more restrictive but simpler API.
