gatsby-plugin-relativeurl v2.1.0

gatsby-plugin-relativeurl

Updates Gatsby generated URLs to be relative, suitable for using file:/// based paths or deploying to IPFS. This is an extension of the exceedingly clever gatsby-plugin-ipfs by André Cruz.

This plugin adds support for literal paths, adding index.html, since browsers cannot handle an implicit index.html in file:/// URLs that point to directories.

Installation

$ npm install --save gatsby-plugin-relativeurl

Usage

Set prefixPath to __GATSBY_RELATIVEURL_PATH_PREFIX__ and include the plugin in your gatsby-config.js file:

module.exports = {
    pathPrefix: '__GATSBY_RELATIVEURL_PATH_PREFIX__',
    plugins: [
        'gatsby-plugin-relativeurl',
    ],
};

And now, simply build the project with npm run build -- --prefix-paths. Better yet, set it by default in your package.json:

"scripts": {
  "build": "gatsby build --prefix-paths"
},

But how?

It turns out the Gatsby doesn't support relative paths. But I didn't gave up and came up with smart and ugly hacks to do so:

• Adds a very small code snippet to every HTML page that defines the __GATSBY_RELATIVEURL_PATH_PREFIX__ global based on the browser location
• Adds a post-build step that iterates over files and transforms every __GATSBY_RELATIVEURL_PATH_PREFIX__ occurrence
