A BBCode parser without any built-in parsing rules, allowing users to implement their own rules.

Usage

1. First of all, create parser

const parser = new BBCodeParser.BBCodeParser();

2. Implement and register parsing rules

A rule for [url=URL]CONTENT[/url] and [url]URL_AS_CONTENT[/url] can be registered like this:

parser.register({
    'url': {
        openTag(params, content) {
            let url = params ?? content;
            url = url.startsWith('http://') || url.startsWith('https://') ? url : 'http://' + url;
            return `<a href="${ url }" target="_blank">`;
        },
        closeTag(params, content) {
            return '</a>'
        },
    }
});

A rule for [b]CONTENT[/b] can be registered like this:

parser.register({
    'b': {
        openTag(params, content) {
            return '<b>';
        },
        closeTag(params, content) {
            return '</b>';
        },
    },
});

And yes, they can be registered with one call:

parser.register({
    'url': {
        openTag(params, content) {
            let url = params ?? content;
            url = url.startsWith('http://') || url.startsWith('https://') ? url : 'http://' + url;
            return `<a href="${ url }" target="_blank">`;
        },
        closeTag(params, content) {
            return '</a>'
        },
    },
    'b': {
        openTag(params, content) {
            return '<b>';
        },
        closeTag(params, content) {
            return '</b>';
        },
    },
});

3. Parse bbcode (and get html if need)

const result = parser.parse('[b]Hello[/b], [url=https://example.com/]bbcode[/url]');

// You can access html or ast / nodes in result object, like
console.log(result.html);
console.log(result.html_ast);
console.log(result.ast);

// Check if there's any error while paring
console.log(result.errors);
