Mime It!

This is a module that helps you access mime information about any file-name, file or even url as well as providing you with the best svg icon for the mime type.

This module was written as part of a file browser so you can imagine getting the complete mime info as well as icons is very useful.

This module combines the power of the following great modules:

• mime-type ~ the custom more powerful mime-type utility can work with mime-db which is itself forked from mime-types.
• axios ~ promise based HTTP client that allows us to access remote files via URL.
• file-type ~ that allows us to detect file types from URL & File buffers.

SVG Icons are generated from This Set.

Fast even for remote files

For remote files, this module will:

• First try and establish type using the content-type headers. Otherwise;
• We download only as much data as is required to establish file type using file-type.

Therefore, even big files are identified in milliseconds.

How To Use

// require
const MimeIt = require('mimeit');
// init
const mimeit = new MimeIt();

// let us get the mime type of an unsplash image
const file =
    'https://plus.unsplash.com/premium_photo-1670390321006-08f58f418429';

(async () => {
    // get mime data
    let mime = await mimeit.get(file);

    console.log('Unsplash URL\n', mime);
    // you can also inspect the meta object
    // which shows what has been done behind the scenes
    console.log(mime.meta);
    // get an svg icon for this meta type
    console.log('Unsplash Icon\n', mime.icon);

    // You can also check file paths & names
    mime = await mimeit.get('/path/to/my-doc.ppt');
    console.log('PPT\n', mime);
    console.log('PPT Icon\n', mime.icon);

    mime = await mimeit.get('/path/to/my-doc.sass')
    console.log('SASS\n', mime);
    console.log('SASS Icon\n', mime.icon);
})();

This 👆 will log the following:

console.log("Unsplash URL\n", mime);

unsplash URL

  type: 'image',
  subType: 'jpeg',
  associatedWith: [ 'picture', 'photo', 'image' ],
  mime: { type: 'image/jpeg', content: 'image/jpeg', charset: null },
  extensions: { current: 'jpeg', all: [ 'jpeg', 'jpg', 'jpe', 'jfif' ] }
}

console.log(mime.meta);

Exposed Mime-Type API

For your convenience, MimeIt and exposes the mime-it api so you essentially don't need another mime-type utility library.

Read the mime-type docs.

Below is what is exposed:

1. The Mime Object

You can access this via:

• mimeit.mime
• mimeit.mime.types
• mimeit.mime.extensions

Example:

mimeit.mime['text/css'];
mimeit.mime.extensions['text/css'];
mimeit.mime.types['text/css'];

2. All Mime-Type Methods

Access the methods via:

• mimeit.lookup
• mimeit.glob
• mimeit.clear
• mimeit.load
• mimeit.delete
• mimeit.define
• mimeit.contentType
• mimeit.extension
• mimeit.charset

In Action

As mentioned, this module was made specifically for use with a file browser. Here is a sample of the browser.

Notice that in addition to showing the correct file, icons, MimeIt even gets it right for "snow-pic.dsx" even if the file extension is wrong. Hence the browser can display the file appropriately.

Enjoy ♥
