Snippet Library.

Create a Secure Webhook Endpoint with Signature Verification

Set up a Node.js Express webhook endpoint to securely receive real-time API updates, including signature verification for data integrity and authenticity.

Fetch All Data from Cursor-Based Paginated API

Efficiently retrieve all available data from APIs using cursor-based pagination (e.g., `next_cursor` or `after_id`) with a Python function.

Perform Concurrent API Requests with Batching

Optimize API integrations by sending multiple requests concurrently using Promise.all in Node.js, effectively batching operations to improve performance.

Cache API Responses with a Time-to-Live (TTL)

Implement a simple in-memory cache with a time-to-live (TTL) for API responses in JavaScript, reducing redundant network requests and improving performance.

Make HTTP Request and Parse JSON Response

Execute HTTP GET/POST requests using curl and parse the JSON response with `jq`, essential for interacting with web APIs directly from your bash scripts.

Start and Monitor a Local Web Development Server

Automate the startup of local development servers (e.g., Node.js, Python, PHP) and optionally tail their logs for real-time monitoring, streamlining your development workflow.

Clean Up Web Project Build Artifacts and Dependencies

Automate the removal of common web project artifacts like `node_modules`, `dist` folders, and cache directories to ensure clean builds and save disk space.

Generate a Basic `sitemap.xml` for Static Sites

Automatically generate a simple `sitemap.xml` file for static websites by scanning local HTML files, improving SEO and site discoverability.

Extract Unique Values from Associative Arrays by Key

Efficiently retrieve all unique values for a specific key across an array of associative arrays, useful for generating distinct lists for filters or dropdowns.

Filter an Array of Associative Arrays by Multiple Criteria

Create a flexible function to filter a list of associative arrays based on multiple dynamic conditions (e.g., price range, category, status) using array_filter.

Deep Merge Associative Arrays

Learn to recursively merge two or more associative arrays in PHP, correctly handling nested arrays and overwriting scalar values in a flexible manner.

Use Prepared Statements to Prevent SQL Injection

Learn how to prevent SQL Injection attacks in Python applications by consistently using prepared statements with parameterized queries, ensuring user input is safely handled.
