PostCSS plugin to replace output file names with HASH algorithms (md5, sha256, sha512, etc) and string length of your choice - for cache busting
npm install postcss-hash[PostCSS] plugin to replace output file names with HASH algorithms (md5, sha256, sha512, etc) and string length of your choice - for cache busting.
``shinput
postcss input.css -o output.css
`
`shinput
postcss css/in/*.css --dir css/out/
Usage
js
// postcss.config.js
module.exports = (ctx) => ({
plugins: {
'postcss-hash': {
algorithm: 'sha256',
trim: 20,
manifest: './manifest.json'
},
}
});
`Options
$3
Uses node's inbuilt [crypto] module. Pass any that is supported in your environment. Possible values are: md5, md4, md2, sha, sha1, sha224, sha256, sha384, sha512.$3
Setting includeMap to true will allow postcss-hash to hash the name of the sourcemap, as well hash the CSS _including_ the sourceMappingURL comment. You can set this option to true if you care about the hashed fingerprints matching the contents of the CSS file, and don't mind a performance hit of regenerating the CSS twice.
$3
Hash's length.$3
Will output a manifest file with key: value pairs.$3
Pass a function to customise the name of the output file. The function is given an object of string values: - dir: the directory name as a string
- name: the name of the file, excluding any extensions
- hash: the resulting hash digest of the file
- ext: the extension of the file
NOTE:
1. The values will be either appended or replaced. If this file needs be recreated on each run, you'll have to manually delete it.
2.
keys are generated with files' basename. If you have ./input/A/one.css & ./input/B/one.css, only the last entry will exist.See [PostCSS] docs for examples for your environment.
