What is attr-accept?

The attr-accept package is designed to provide functionality for checking if a file meets certain criteria specified through file attributes. This is particularly useful in scenarios where file uploads need to be validated based on file type, name, or other attributes before being processed or accepted. It's commonly used in web development projects to enhance the file upload feature by filtering out unacceptable files based on their attributes.

What are attr-accept's main functionalities?

File Type Validation

This feature allows developers to validate the type of the file by specifying a MIME type pattern. In the code sample, the function `accepts` is used to check if a file named 'example.jpg' with the MIME type 'image/jpeg' matches the specified pattern 'image/*'. This is useful for ensuring that only files of a certain type are processed.

const accepts = require('attr-accept');

const file = {
  name: 'example.jpg',
  type: 'image/jpeg'
};

const accepted = accepts(file, 'image/*');
console.log(accepted); // true or false

File Extension Validation

This feature enables the validation of files based on their extension. The provided code demonstrates how to use the `accepts` function to verify if a file with the name 'example.pdf' and the type 'application/pdf' has a '.pdf' extension. This can be particularly useful for applications that only need to accept files with specific extensions.

const accepts = require('attr-accept');

const file = {
  name: 'example.pdf',
  type: 'application/pdf'
};

const accepted = accepts(file, '.pdf');
console.log(accepted); // true or false
