QUESTION

how to to host single-spa root-config and modules on a central server during development

Asked 2020-Dec-13 at 22:20

I've been experimenting with single-spa for a while, and understand the basics of the developer experience. Create a parcel, yarn start on a unique port, add the reference to the import map declaration, and so on. The challenge with this is that as my root-config accrues more and more modules managing ports and import-maps starts to get tedious. What I want is to publish these modules to a central repository and load them from there (e.g., http://someserver.com/repository/moduleA/myorg-modulea.js, etc.).

I was recently introduced to localstack and started thinking maybe a local S3 bucket would serve for this. I have a configuration where builds (yarn build) are automatically published to an s3 bucket running on localstack. But when I try to load the root config index.html from the bucket I get the following JS error:

I had a similar issue that I got to work with http-server by adding each child .js file to a sub-folder in the root-config directory and launching the web server at the root-config directory level.

Install import-maps

You can install an import map for your application using a <script> element, either inline or with a src="" attribute:. When the src="" attribute is used, the resulting HTTP response must have the MIME type application/importmap+json. (Why not reuse application/json? Doing so could enable CSP bypasses.) Like module scripts, the request is made with CORS enabled, and the response is always interpreted as UTF-8. Because they affect all imports, any import maps must be present and successfully fetched before any module resolution is done. This means that module graph fetching is blocked on import map fetching. This means that the inline form of import maps is strongly recommended for best performance. This is similar to the best practice of inlining critical CSS; both types of resources block your application from doing important work until they're processed, so introducing a second network round-trip (or even disk-cache round trip) is a bad idea. If your heart is set on using external import maps, you can attempt to mitigate this round-trip penalty with technologies like HTTP/2 Push or bundled HTTP exchanges. As another consequence of how import maps affect all imports, attempting to add a new <script type="importmap"> after any module graph fetching has started is an error. The import map will be ignored, and the <script> element will fire an error event. For now, only one <script type="importmap"> is allowed on the page. We plan to extend this in the future, once we figure out the correct semantics for combining multiple import maps. See discussion in #14, #137, and #167.

Support

It is natural for multiple <script type="importmap">s to appear on a page, just as multiple <script>s of other types can. We would like to enable this in the future. The biggest challenge here is deciding how the multiple import maps compose. That is, given two import maps which both remap the same URL, or two scope definitions which cover the same URL prefix space, what should the affect on the page be? The current leading candidate is cascading resolution, which recasts import maps from being import specifier → URL mappings, to instead be a cascading series of import specifier → import specifier mappings, eventually bottoming out in a "fetchable import specifier" (essentially a URL). See these open issues for more discussion.
