I'm configuring Webpacks output and i have run into some examples which have this unusual syntax added on the end.
output: {
filename: '[name][fullHash:8].bundle.js',
chunkFilename: '[name][fullHash:8].bundle.js',
path: `${__dirname}/dist`,
publicPath: "/",
},
Ok now you see the :8's after fullhash? what extra feature does it provide? My first guess was UTF-8??? But that's just a stab in the dark.
So from a quick little search in the docs, I found this one section which talks about it
The length of hashes ([hash], [contenthash] or [chunkhash]) can be specified using [hash:16] (defaults to 20). Alternatively, specify output.hashDigestLength to configure the length globally.
So going by that, it would probably mean that [fullHash:8] would produce a hash of length 8, which I suppose I would advice against, and would be better off to keep it at the default of 20 (by just removing the :8).
