The Ultimate
Snippet Library.

Create a Reusable and Robust API Client for Fetch

Develop a generic API client class in JavaScript to centralize HTTP requests, manage headers, handle errors consistently, and streamline API integrations.

Securely Access Third-Party APIs via Server-Side Proxy

Learn to protect sensitive API keys by making third-party API calls from your backend server, acting as a proxy to prevent exposure in client-side code.

Implementing Exponential Backoff for API Retries

Learn to build a robust API integration with exponential backoff and jitter, ensuring resilience against transient network or server errors for more reliable data fetching.

Client-Side Rate Limiting API Requests

Implement a client-side rate limiter using a queue to control the frequency of API requests, preventing exceeding external service limits and ensuring fair usage.

Handling Cursor-Based Pagination for API Results

Efficiently fetch large datasets from APIs using cursor-based pagination, navigating through results with `next_cursor` tokens for scalable data retrieval.

Consuming Real-Time Updates with Server-Sent Events (SSE)

Integrate real-time data streams into your web application by consuming Server-Sent Events (SSE), enabling push notifications and live updates from an API.

Uploading Files to an API with FormData

Learn to securely upload files to a backend API using `FormData` and `fetch`, handling common scenarios like progress tracking and associating metadata.

Load Environment Variables from File

A bash script to parse key-value pairs from a file (like .env) and export them as environment variables, enabling flexible and secure application configuration management.

Check if Process is Running and Restart if Down

A bash script to monitor a specific application process by name and automatically restart it if it's found to be down, ensuring continuous service availability for web applications.

Perform a Basic HTTP Endpoint Health Check

A bash script designed to perform a basic HTTP endpoint health check using curl, verifying the HTTP status code for robust service monitoring and quick issue detection in web apps.

Automate Git Operations and Check Status

A bash script to automate common Git operations like pulling latest changes, pushing committed code, and checking the repository status, simplifying development and deployment workflows.

Extract Value from Key-Value Configuration File

A bash script to parse a simple key-value configuration file and extract the specific value for a given key, useful for dynamically reading application settings into other scripts.
