The 'anser' npm package is a library that allows you to convert ANSI escape codes into HTML. This is particularly useful for rendering terminal output in web applications, where you want to preserve the color and style formatting.
Convert ANSI to HTML
This feature allows you to convert a string containing ANSI escape codes into an HTML string with equivalent styling. The example converts a red-colored 'Hello, World!' from ANSI to HTML.
const anser = require('anser');
const ansiString = '\u001b[31mHello, World!\u001b[0m';
const htmlString = anser.toHtml(ansiString);
console.log(htmlString); // Outputs: <span style="color:#E34C26;">Hello, World!</span>Strip ANSI codes
This feature allows you to strip ANSI escape codes from a string, leaving just the plain text. The example removes the red color formatting from 'Hello, World!'.
const anser = require('anser');
const ansiString = '\u001b[31mHello, World!\u001b[0m';
const plainString = anser.ansiToText(ansiString);
console.log(plainString); // Outputs: Hello, World!Escape for HTML
This feature escapes HTML special characters in a string containing ANSI escape codes. The example converts '<' and '>' to their HTML entities.
const anser = require('anser');
const ansiString = '\u001b[31mHello, <World>!\u001b[0m';
const escapedHtmlString = anser.escapeForHtml(ansiString);
console.log(escapedHtmlString); // Outputs: \u001b[31mHello, <World>!\u001b[0mChalk is a popular library for styling terminal strings in Node.js. Unlike 'anser', which focuses on converting ANSI codes to HTML, Chalk is primarily used for creating styled terminal output. It supports various styles and colors but does not provide HTML conversion.
The 'ansi-to-html' package is similar to 'anser' in that it converts ANSI escape codes to HTML. However, 'anser' offers more features like stripping ANSI codes and escaping for HTML, making it a more versatile choice for handling ANSI codes.
The 'strip-ansi' package is a simple utility for removing ANSI escape codes from strings. While it performs a similar function to 'anser's' ansiToText method, it lacks the additional features like HTML conversion and escaping.
A low level parser for ANSI sequences.
# Using npm
npm install --save anser
# Using yarn
yarn add anser
const Anser = require("anser");
const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
console.log(Anser.ansiToHtml(txt));
// <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>
console.log(Anser.ansiToHtml(txt, { use_classes: true }));
// <span class="ansi-palette-196-fg">Hello</span> <span class="ansi-palette-226-bg">World</span>
console.log(Anser.ansiToJson(txt));
// [ { content: '',

When using TypeScript without --esModuleInterop enabled you can do the following:
import Anser = require('anser');
const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
console.log(Anser.ansiToHtml(txt));
// <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>
Or with --esModuleInterop enabled you can do the following:
import Anser from 'anser';
const txt = "\u001b[38;5;196mHello\u001b[39m \u001b[48;5;226mWorld\u001b[49m";
console.log(Anser.ansiToHtml(txt));
// <span style="color:rgb(255, 0, 0)">Hello</span> <span style="background-color:rgb(255, 255, 0)">World</span>
There are few ways to get help:
Add several widely used style codes
processChunk(text, options, markup)Processes the current chunk of text.
text: The input text.options: An object containing the following fields:json (Boolean): If true, the result will be an object.use_classes (Boolean): If true, HTML classes will be appended to the HTML output.markup: If false, the colors will not be parsed.json is wanted back or string otherwise).Have an idea? Found a bug? See how to contribute.
I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).
However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:
Starring and sharing the projects you like :rocket:
—I love books! I will remember you after years if you buy me one. :grin: :book:
—You can make one-time donations via PayPal. I'll probably buy a coffee tea. :tea:
—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6
Thanks! :heart:
This project is highly based on ansi_up, by @drudru. Thanks! :cake:
If you are using this library in one of your projects, add it in this list. :sparkles:
