Snippet Library.

Making a PATCH Request to Update a Partial Resource

Learn to send a `PATCH` request using JavaScript's `fetch` API for efficient partial updates to resources, sending only changed fields to the server.

Optimizing API Calls with ETag and If-None-Match

Learn to optimize API requests using HTTP ETag headers and the If-None-Match condition to reduce bandwidth and server load by fetching data only when it has changed.

Implementing a Circuit Breaker for Resilient API Calls

Enhance API call resilience using the Circuit Breaker pattern to prevent cascading failures by temporarily blocking requests to services experiencing issues.

Uploading Multiple Files to an API with FormData

Discover how to efficiently upload multiple files to an API endpoint using JavaScript's FormData object, perfect for forms requiring several file attachments.

Implementing Graceful API Degradation with Fallbacks

Learn to implement graceful degradation for API integrations by providing fallback data or a simplified UI when primary API calls fail, improving user experience.

Performing GraphQL Mutations with Vanilla JavaScript

Execute GraphQL mutations using vanilla JavaScript and the fetch API to create, update, or delete data, providing direct interaction with your GraphQL backend.

Flatten a Multi-dimensional Array into a Single Array

Learn how to convert a nested PHP array into a single-level array efficiently using recursion, useful for simplifying complex data structures.

Remove Duplicate Associative Array Elements Based on a Key

Efficiently filter out duplicate associative array elements in PHP by checking for uniqueness against a specified key's value, preserving the first occurrence.

Transform Array of Records into Key-Value Map

Efficiently convert an array of associative arrays (like database records) into a simpler key-value map in PHP, ideal for dropdowns or lookups.

Deep Merge Associative Arrays Recursively with Overwrite

Implement a custom PHP function to recursively merge two associative arrays, correctly overwriting scalar values and intelligently merging nested arrays.

Randomly Shuffle Associative Array Preserving Keys

Learn how to randomly reorder an associative array in PHP while maintaining the key-value pair associations, as `shuffle()` resets numeric keys.

Simple Node.js Proxy for Third-Party APIs

Learn how to create a basic Node.js proxy server using Express to securely access third-party APIs from your frontend, bypassing CORS restrictions and hiding API keys.
