None of them are groundbreaking, but they solve real problems I personally ran into, and I figured someone else might find them useful too.</p> <p>All three are free, open-source, and open to contributions or feedback.</p> <h2> 1. Discord Guard Bot — Security Duki 1.1 </h2> <p>A moderation bot built after getting tired of raid bots and spam in a few Discord servers I help manage.</p> <p><strong>Features:</strong></p> <ul> <li>Blacklist system — auto-kicks bots added to a blocklist via <code>/bl</code> command</li> <li>Anti-spam protection — configurable message limit before timing out a user (default: 5 messages → 1 hour mute)</li> <li>Unauthorized channel creation gets auto-deleted unless the member has a specific role</li> <li>Link-sharing restricted to members with permission</li> </ul> <p><strong>Stack:</strong> Node.js, discord.js v14, MongoDB (Mongoose)</p> <p>🔗 <a href="https://github.com/qptqpt199-prog/Security-Duki-1.1.git" rel="noopener noreferrer">github.com/qptqpt199-prog/Security-Duki-1.1</a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fexz7rixbe115u54kzos4.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fexz7rixbe115u54kzos4.png" alt=" " width="800" height="360"></a></p> <h2> 2. Simple Auth System — Login Interface </h2> <p>A clean login/register boilerplate I built as a reusable starting point for future projects that need authentication without pulling in a massive framework.</p> <p><strong>Features:</strong></p> <ul> <li>Passwords hashed with bcrypt (never stored in plain text)</li> <li>Sessions stored in MongoDB instead of localStorage — more resistant to XSS</li> <li>Protected dashboard route via custom middleware</li> </ul> <p><strong>Stack:</strong> Node.js, Express, MongoDB</p> <p>🔗 <a href="https://github.com/qptqpt199-prog/Login-interface.git" rel="noopener noreferrer">github.com/qptqpt199-prog/Login-interface</a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F59r4zggzp5nc00bcp9s3.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F59r4zggzp5nc00bcp9s3.png" alt=" " width="800" height="343"></a></p> <h2> 3. JS Whitespace &amp; Indentation Formatter </h2> <p>A lightweight script that automatically fixes spacing and indentation in messy JavaScript code snippets.</p> <p>I'm not trying to compete with Prettier here — this was mostly a fun exercise in string manipulation and regex that ended up being genuinely usable for quick fixes.</p> <p>🔗 <a href="https://github.com/qptqpt199-prog/Automatic-Formatting-and-Whitespace-Addition-Function-for-JS-Code.git" rel="noopener noreferrer">github.com/qptqpt199-prog/Automatic-Formatting-and-Whitespace-Addition-Function-for-JS-Code</a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fble5nzqikv5r8rb7opqq.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fble5nzqikv5r8rb7opqq.png" alt=" " width="800" height="338"></a></p> <h2> Feedback welcome </h2> <p>All three repos are licensed and open to pull requests. If you try any of them out, I'd genuinely appreciate bug reports or suggestions — this is still early-stage work and there's plenty of room to improve.</p> <p>Thanks for reading!</p> ai webdev discord javascript
