Mime-type of stream

The @flystorage/stream-mime-type package provides a utility to determine the mime-type of a stream in a non-destructive way.

Underneath, the package uses the file-type and mime-types packages to resolve the mime-type of the stream. It first tries to determine the mime-type based on the file contents and will fall back to resolving it based on the file extension.

Installation

npm install --save @flystorage/stream-mime-type

Usage

Resolve a mime-type:

import {resolveMimeType} from '@flystorage/stream-mime-type';

const originalStream = fs.createReadStream(pathToFile);

const [mimetype, stream] = resolveMimeType(filename, originalStream);

Sampling the start of a stream:

import {streamHead} from '@flystorage/stream-mime-type';

const originalStream = fs.createReadStream(pathToFile);

const [sample, stream] = streamHead(originalStream, sizeInBytes);
