Introduction: Revolutionizing Browser Extension Capabilities

Social Browser's Custom Extensions platform represents a quantum leap in browser extension technology, providing developers with unprecedented access to low-level browser architecture. Unlike traditional browsers that restrict extensions to superficial APIs, Social Browser opens the complete power of NodeJS, ElectronJS, and Chromium to extension developers. This comprehensive guide explores the technical architecture, capabilities, and implementation strategies for building powerful extensions with full system access, enabling functionality previously impossible in browser environments.

Getting Started Guide

Initial Setup

Environment preparation steps:

Install Social Browser Only
Use vs code or any editor
create New folder
create index.js , preload.js , index.html files
write this code for example

Hello World Example

Main entry extension File ( index.js )

module.exports = function (browser) {
    let extension = {};
    extension.id = '__TikTok';
    extension.name = 'tiktok';
    extension.description = 'Tiktok Tool Managemet';
    extension.paid = false;
    extension.version = '1.0.0';
    extension.canDelete = false;
    extension.init = () => {
        console.log('Tiktok Tool init');
    };
    extension.enable = () => {
        browser.addPreload({
            id: extension.id,
            path: browser.path.join(__dirname, 'preload.js'),
        });

        browser.api.onGET({ name: '/extentions/tiktok', overwrite: true }, (req, res) => {
            res.render(__dirname + '/index.html', {}, { parser: 'html css js', parserDir: __dirname });
            browser.api.fsm.off('*tiktok*');
        });
    };

    extension.disable = () => {
        browser.removePreload(extension.id);
        browser.api.fsm.off('*tiktok*');
    };

    extension.remove = () => {
        extension.disable();
    };

    return extension;
};

( preload.js )

SOCIALBROWSER.addMenu({
    label: '[ Tiktok Tool Manager]',
    click() {
        document.location.href = 'http://127.0.0.1:60080/extentions/tiktok';
    },
});

SOCIALBROWSER.addMenu({
    type: 'separator',
});

SOCIALBROWSER.onLoad(() => {});

Conclusion: Unleashing Browser Extension Potential

Social Browser's Custom Extensions with full low-level access to NodeJS, ElectronJS, and Chromium represent a fundamental shift in what's possible with browser extensions. By removing the artificial barriers between web content and system resources, developers can now create extensions with capabilities rivaling native applications while maintaining all the advantages of the browser ecosystem.

This comprehensive access comes with significant responsibility - the power to modify core browser behavior and access system resources requires careful security consideration and thoughtful architecture. However, for developers willing to master these capabilities, the possibilities are virtually limitless.

As the extension ecosystem evolves, Social Browser's open approach to low-level access positions it as the premier platform for ambitious browser extension development, blurring the lines between web applications and native software in ways that will shape the future of computing.
