Convert a string to a valid safe filename
npm install filenamify> Convert a string to a valid safe filename
On Unix-like systems, / is reserved. On Windows, <>:"/\|?* along with trailing periods and spaces are reserved.
This module also removes non-printable control characters (including Unicode bidirectional marks) and normalizes Unicode whitespace.
``sh`
npm install filenamify
`js
import filenamify from 'filenamify';
filenamify('
//=> '!foo!bar!'
filenamify('foo:"bar"', {replacement: '🐴'});
//=> 'foo🐴bar🐴'
`
Convert a string to a valid filename.
Convert the filename in a path to a valid filename and return the augmented path.
`js
import {filenamifyPath} from 'filenamify';
filenamifyPath('foo:bar');
//=> 'foo!bar'
`
#### options
Type: object
##### replacement
Type: string\'!'
Default:
String to use as replacement for reserved filename characters.
Cannot contain: < > : " / \ | ? * or control characters.
##### maxLength
Type: number\100
Default:
Truncate the filename to the given length.
Only the base of the filename is truncated, preserving the extension. If the extension itself is longer than maxLength, you will get a string that is longer than maxLength, so you need to check for that if you allow arbitrary extensions.
Truncation is grapheme-aware and will not split Unicode characters (surrogate pairs or extended grapheme clusters). If the remaining budget (after accounting for the extension) is smaller than a whole grapheme, the base filename may be truncated to an empty string to avoid splitting.
Systems generally allow up to 255 characters, but we default to 100 for usability reasons.
You can also import filenamify/browser, which only imports filenamify and not filenamifyPath, which relies on path being available or polyfilled. Importing filenamify this way is therefore useful when it is shipped using webpack or similar tools, and if filenamifyPath is not needed.
`js
import filenamify from 'filenamify/browser';
filenamify('
//=> '!foo!bar!'
