Monorepos are MORE powerful than npm packages. It DOES indeed allow for independent builds and separate deployments, if you configure the CI accordingly.

Thanks for your work on this.

Awesome! Btw, have you looked into Snowpack at all? Looks way more modern & more powerful than Webpack

Apologies in advance for hijacking a PR discussion for a personal question, but:

@kristianmandrup For a variety of reasons, we've concluded a monorepo is the right direction for our project -- but our team is generally new to modern-style JS development. Are you aware of a public single-spa monorepo project (ideally react-based!) that we could study? This is one of those scenarios where the team was just thrown into the deep end without any warning -- and we have to get it right the first time. It's for new, large, complex business application.

(I had also been thinking about Snowpack, but we're so new to the JS-way that we figured it's safest to stick with Webpack. It seems to be something we could switch to later on when our project is stable.)

@MV10 Cheers! At my work we are migrating from a poly repo micro site application to a proper unified single spa application, using Nx to manage the mono repo aspect. We are integrating this with Jenkins CI. Currently we have our Nx mono repo in place with linting, Jest unit tests, E2E using cypress and storybook. Jenkins CI is configured to use the nx CLI to only run linting, tests and builds on affected modules (compared to latest commit on master branch) on each commit.
If all tests pass, we then push the dist files to an S3 bucket and update the relevant importmap.json with the new entries, via REST API calls to our Import Maps deployer (web server).

We plan to use snowpack and webpack federated modules later. We do not have anything to share at the moment unfortunately. Note that in our first iteration, we will be using a simple static index.html file that does not leverage single-spa. Later when we have our POC working, we certainly want to take advantage of single-spa.

• nx-jenkins-build
• Guide monorepo CI jenkins

Will keep you posted. We hope to have our POC up and working by end of December.
