Minify HTML Stream

Strips whitespace from an HTML stream to reduce the size of the final payload.

Install

Install with npm

npm install --save minify-html-stream

Simple Example

"use strict";

const fetch = require("node-fetch");
const Minifier = require("minify-html-stream").Minifier;

fetch("http://example.com/").then(function (response) {
    response.body.pipe(new Minifier()).pipe(process.stdout);
}).catch(function (err) {
    console.error("Yikes!", err);
});

How You Might Use It

"use strict";

// Declare variables
const http = require("http");
const talisman = require("talismanjs");
const Minifier = require("minify-html-stream").Minifier;

// Start a server
const server = http.createServer(function (request, response) {
    talisman.create("homepage.html").then(function (view) {
        view.toStream().pipe(new Minifier()).pipe(response);
    }).catch(function (error) {
        response.writeHead(500);
        response.write(error.message);
        response.end();
    });
});

// Start listening
server.listen(8000);

Configuration

{
    stripCarriageReturns: true, // remove carriage return characters (\r)
    trimLines: true, // remove whitespace from the ends of lines
    trimElements: true, // remove whitespace from around elements where it is safe
    normalizeWhiteSpace: true, // normalize multiple whitespace characters to single characters
    stripComments: true // remove HTML comments (except conditional comments)
}

Notes

Minify HTML Stream is really naïve and conservative about how it goes about minification, because it sort of has to be. Pull requests are most welcome.
