Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

express-unless

v2.1.3

Published

Conditionally add a middleware to express with some common patterns.

Downloads

2,445,923

Readme

Conditionally skip a middleware when a condition is met.

Install

npm i express-unless --save

Usage

With existing middlewares:

var { unless } = require("express-unless");

var static = express.static(__dirname + "/public");
static.unless = unless;

app.use(static.unless({ method: "OPTIONS" }));

If you are authoring a middleware you can support unless as follow:

var { unless } = require("express-unless");

module.exports = function (middlewareOptions) {
  var mymid = function (req, res, next) {};

  mymid.unless = unless;

  return mymid;
};

Current options

  • method it could be an string or an array of strings. If the request method match the middleware will not run.
  • path it could be an string, a regexp or an array of any of those. It also could be an array of object which is url and methods key-pairs. If the request path or path and method match, the middleware will not run. Check Examples for usage.
  • ext it could be an string or an array of strings. If the request path ends with one of these extensions the middleware will not run.
  • custom it must be a function that accepts req and returns true / false. If the function returns true for the given request, the middleware will not run.
  • useOriginalUrl it should be true or false, default is true. if false, path will match against req.url instead of req.originalUrl. Please refer to Express API for the difference between req.url and req.originalUrl.

Examples

Require authentication for every request unless the path is index.html.

app.use(
  requiresAuth.unless({
    path: ["/index.html", { url: "/", methods: ["GET", "PUT"] }],
  })
);

Avoid a fstat for request to routes doesnt end with a given extension.

app.use(
  static.unless(function (req) {
    var ext = url.parse(req.originalUrl).pathname.substr(-4);
    return !~[".jpg", ".html", ".css", ".js"].indexOf(ext);
  })
);
