powahroot

Client and server-side routing micro frameworks

Powahroot is a pair of micro routing frameworks, presented as an ES6 module:

• The first is for client-side single-page web applications
• The other is for handling server-side Node.js requests

It's based on rill (see the npm package bearing the name), but stripped down and simplified.

• Current version:
• Changelog: https://github.com/sbrl/powahroot/blob/main/CHANGELOG.md

Getting Started

Install powahroot as a dependency with npm:

npm install --save powahroot

If your build process supports tree-shaking, only the router(s?) you need will be included in the final output of your build - as powahroot uses ES6 modules.

Usage

Paths

Powahroot supports multiple syntax bells and whistles when defining routes. These are documented below:

Syntax	Meaning
/index.html	Regular route. Matches exactly what it says on the tin.
*	Special key(word?) that matches any route. Must be present on its own without any other characters.
/add/vegetable/:name/:weight	Parameters. Match values an pull them into an object automatically. Does not like forward slashes in parameter values.
/images/::path	Parameter values with forward slashes. If you want to use parameters, but need values to be able to contain forward slashes /, this is for you. Don't forget you can mix-and-match this with the previous example!

Client

Initialise a new router like this:

import ClientRouter from 'powahroot/Client.mjs';

// ....

const router = new ClientRouter({
	// Options object. Default settings:
	verbose: false, // Whether to be verbose in console.log() messages
	listen_pushstate: true, // Whether to react to browser pushstate events (excluding those generated by powahroot itself, because that would cause an infinite loop :P)
});

// Add a page
router.add_page("/add/vegetable/:name/:weight", (params) => {
    console.log(`We added a ${params.name} with a weight of ${params.weight}g.`);
});

// Explicitly navigate to a page:
router.navigate("/add/carrot/frederick/10001");

Server

The server router works slightly differently, to account for the different environment it's designed for. Here's how to use it:

import ServerRouter from 'powahroot/Server.mjs';

// ....

const router = new ServerRouter();
// Logging middle ware
router.on_all(async (context, next) => {
    console.debug(context.url);
    await next();
});
// Regular handlere
router.get("/files/::filepath", (context, _next) => context.send.plain(200, `You requested ${context.params.filepath}`));
// .....

// Later, when you've got a request / response pair to handle:
await router.handle(request, response);

The context argument there is of type RouterContext. Check out the API reference (link below) to learn about the other useful properties it has.
