Webpack Asset Map Plugin
Creates a json file that any server side technology can consume for asset declarations. Example output file:
{
"assets": {
"./smiley.jpeg": "/assets/smiley-db4f287d06928156270ca185fef0e026.jpeg",
"./test-checklist.jpeg": "/assets/test-checklist-b3b0fe76f4485db43467876f664d1f62.jpeg"
},
"chunks": {
"index": [
"/assets/index-2c9c445686f51177cf62.js"
"/assets/index-2c9c445686f51177cf62.css"
]
}
}The key is the relative path from the generated file to the image location in your source location. The value is the public url slug generated by webpack.
