Question: how do I override the public path of assets

[Checksum]

Is there a way to set the base path for assets, similar to webpack's publicPath setting? (https://webpack.js.org/guides/public-path/). I can't find that option for the CLI and can't seem to find a related issue as well.

Can you say more about what you expect to happen? I don't use Webpack myself and the documentation you linked to doesn't tell me anything about what this feature does. What changes about the generated files when this setting is changed?

react-native bundler also has a option to define a different output destination for the assets

--assets-dest

The webpack build-time publicPath option (and runtime __webpack_public_path__ variable) is used to determine the path for loading assets and chunks (depending on the chunk loading method).

By default, for web bundles, webpack uses a JSONP method for dynamically loading chunks wherein <script> tags are appended to the DOM. The public path is essentially path prefix. Typically, you would set publicPath to something like /assets/ or https://cdn.example.com/

In addition to chunk loading, it also used to determine paths to other assets. For example, if you are using file-loader for .png files and have set the publicPath to a CDN:

import imgPath from "./my-image.png";

console.log(imgPath);
// https://cdn.example.com/my-image-e3087eadb38c752.png

---

Because esbuild currently only supports ESM output when using --splitting, I don't think there's a need for a public path option for chunk loading. However, this would be useful for the esbuild file loader.

Sorry for the pretty thin description, I really shouldn't create issues on my mobile. @rtsao has explained it well. The publicPath is the base URL for all the assets that are generated by a loader. For example:

const style = require("./style.css");
console.log(style);
// style.T5D2JDNG.css

If deploying this bundle to a CDN with a relative path, say https://cdn.example.com/v1/, the absolute path to the file should be https://cdn.example.com/v1/style.T5D2JDNG.css. By default publicPath is empty and hence is relative, but explicitly setting a base path is required quite often.

Just for those like me stumbling across this and because the feature request is still open: here's a documented setting exactly as requested: https://esbuild.github.io/api/#public-path

Did you use that and it's working @jhohlfeld ?
