file-groups

File extensions and media types, grouped by application and type. Useful when you need to process or restrict processing to certain types of files.

Usage

Properties on file-groups return objects containing a set of media types and file extensions. These are accessible via the mediaTypes and extensions properties, which return an Array of Strings. By default only commonly used values are returned. To return all know values pass true to either, e.g., object.mediaTypes(true)

In some cases additional methods can be called on the object to further restrict the set.

Let's look at some examples.

Images & Video

Retrieve a list of file extensions or media types used by images and video:

const fileGroups = require('file-groups');

fileGroups.image.extensions();  // ["bmp", "gif", "ico", "jpeg", ... ]
fileGroups.image.mediaTypes();  // ["image/bmp", "image/x-ms-bmp", "image/gif", ... ]
fileGroups.video.extensions();  // ["asf", "mov", "qt", "movie", ... ]
fileGroups.video.mediaTypes();  // ["video/x-ms-asf", "video/quicktime", ... ]

Images can be filtered on by raster, vector, or web:

fileGroups.image.web.extensions();     // ["gif", "jpeg", "jpg", "png", "svg", "webp"]
fileGroups.image.raster.extensions();  // ["bmp", "gif", "ico", "jpeg", "jpg", "tif", "tiff", "webp"]
fileGroups.image.vector.extensions();  // ["svg"]

For a complete list pass in true to any of these methods:

fileGroups.image.extensions(true);  // ["bmp", "dib", "gif", "ico", "jfif", "jpe", "jpeg", ... ]

Spreadsheets

Retrieve a list of file extensions or media types used by spreadsheets:

const fileGroups = require('file-groups');

fileGroups.spreadsheet.extensions();  // ["csv", "xls", "xlsx", "xlt", ... ]
fileGroups.spreadsheet.mediaTypes();  // ["text/csv", "application/vnd.ms-excel", ... ]

If you only want values specific to CSVs:

fileGroups.spreadsheet.csv.mediaTypes();  // ["text/csv", "text/comma-separated-values" ]

If you only want values specific to Microsoft Excel:

fileGroups.spreadsheet.excel.extensions();  // ["xls", "xlsx", "xlt", "xltx", "xlw"]
fileGroups.spreadsheet.excel.mediaTypes();  // ["application/vnd.ms-excel", ... ]

Or for OpenOffice Calc:

fileGroups.spreadsheet.calc.extensions();  // ["ods", "ots"]

By default these only return common extensions, to return all:

fileGroups.spreadsheet.excel.extensions(true); // ["xls", "xlsx", "xlt", "xltx", ... ]
