@push.rocks/smartmime

a module to detect mime types

Install

Installing @push.rocks/smartmime is as simple as running the following npm command in your terminal. Make sure you have Node.js (version 10.x or newer) installed on your machine.

npm install @push.rocks/smartmime --save

This command will download @push.rocks/smartmime and add it to your project's package.json file.

Usage

@push.rocks/smartmime is a versatile TypeScript module designed for mime type detection, supporting a variety of file types including images (JPG, PNG), text (HTML, SVG), application data (JSON), and scripts (TS, JS). Utilizing ESM syntax, this guide demonstrates its comprehensive feature set.

Basic Mime Type Detection

To start, you can use the detectMimeType function to analyze a file path and return its mime type. Supported mime types include image/jpeg, image/svg+xml, application/json, text/html, etc.

import { detectMimeType } from '@push.rocks/smartmime';

// Example: Detecting the mime type of a JPEG image
const imagePath = 'path/to/image.jpg';
const imageMimeType = detectMimeType(imagePath);
console.log(imageMimeType); // Output: 'image/jpeg'

// Example: Detecting the mime type of an SVG
const svgPath = 'path/to/design.svg';
const svgMimeType = detectMimeType(svgPath);
console.log(svgMimeType); // Output: 'image/svg+xml'

Checking if a File is Binary

Determining whether a file is binary (e.g., images, PDFs) or text-based (e.g., HTML, TypeScript) is crucial for data handling. The isBinary function facilitates this by returning a boolean value.

import { isBinary } from '@push.rocks/smartmime';

// Example: Checking if a PNG image is binary
const binaryCheckPath = 'path/to/image.png';
console.log(isBinary(binaryCheckPath)); // Output: true

// Example: Checking if a CSS file is binary
const cssPath = 'path/to/styles.css';
console.log(isBinary(cssPath)); // Output: false

Getting File Encoding

Knowing a file's encoding is essential for reading or writing operations. The getEncoding function returns 'binary' for binary files and 'utf8' for text-based files.

import { getEncoding } from '@push.rocks/smartmime';

// Example: Getting encoding for a PDF document
const pdfPath = 'path/to/document.pdf';
console.log(getEncoding(pdfPath)); // Output: 'binary'

// Example: Getting encoding for a JavaScript file
const scriptPath = 'path/to/script.js';
console.log(getEncoding(scriptPath)); // Output: 'utf8'

Supported File Types

@push.rocks/smartmime has predefined support for a select list of binary and text file types, including JSON, HTML, SVG, JPG, TS, and JS. This predefined list ensures quick integration for common file handling scenarios, but the library's core functions can be leveraged for a broader set of file types as it relies on the comprehensive mime-types library for mime type detection.

Advanced Usage

Given the modular and straightforward design of @push.rocks/smartmime, it is seamlessly integrable into file processing pipelines, web server implementations, or any application requiring mime type detection. Its functionality extends beyond simple file type checking, allowing for sophisticated file type validations, content-based routing, or conditional processing based on detected mime types.

By utilizing TypeScript, @push.rocks/smartmime not only offers strong typing advantages for development time introspection but also ensures compatibility with modern JavaScript projects taking advantage of ES modules.

Conclusion

@push.rocks/smartmime encapsulates a powerful set of functionalities for mime type detection, addressing common needs in file handling with an easy-to-use API. Whether for basic checks or integrated into larger processing pipelines, it stands as a valuable tool for developers needing reliable mime type detection in their Node.js or TypeScript projects.
