gatsby-plugin-remove-fingerprints

Easily remove the output contenthash from your built JavaScript files.

Install

yarn add gatsby-plugin-remove-fingerprints

How to use

Add the plugin to your

``js
// In your gatsby-config.js
plugins: [gatsby-plugin-remove-fingerprints];
`

Why?

Gatsby's default behaviour is to include a [contenthash] for all built JavaScript files. The default output configuration looks like this:

`js
return {
filename: [name]-[contenthash].js,
chunkFilename: [name]-[contenthash].js,
path: directoryPath(public),
publicPath: withTrailingSlash(publicPath),
};
`

This is useful for the majority of cases, but services like Netlify recommend building files without a hash. This plugin will eliminate the hash from built JavaScript files. The configuration looks like this:

`js
if (stage === 'build-javascript') {
const newWebpackConfig = {
...getConfig(),
output: {
filename: [name].js, // no contenthash
chunkFilename: [name].js, // no contenthash
path: getConfig().output.path,
publicPath: getConfig().output.publicPath,
},
};

actions.replaceWebpackConfig(newWebpackConfig);
}
``
