• MFE build time

  • 1hr+ to build MFEs

  • Number of MFEs has not changed since Quince – 10 (https://github.com/overhangio/openedx-release-demo/blob/master/.github/workflows/deploy.yml#L101 )

  • Custom npm registries

    • Local deployment of an npm registry

      • vs. shared npm registry

    • devstack had devpi for python reqs

      • devpi is pretty easy to set up

    • install vs build - which is the problem?

      • both

    • building all MFEs (except Learner Dash) without cache on AWS spot fleet m5.xlarge

      • parallelism=4

      • Duration: 43 minutes 4 seconds

    • https://docs.openedx.org/projects/openedx-proposals/en/latest/architectural-decisions/oep-0065-arch-frontend-composability.html

  • Max number of simultaneous connections to npm registry by IP address

• why does the network connection break when we have too much parallelism in the build?

  • this seems different than the npm connection limitation. seems that the host’s network connection is failing

    • saturation of bandwidth?

  • to build mfes in sandbox, had to explicitly set max_parallelism=2

• Solutions

  • Sharing dependencies across MFEs

    • Hinted at in https://docs.openedx.org/projects/openedx-proposals/en/latest/architectural-decisions/oep-0065-arch-frontend-composability.html#caveat-build-time-and-dependency-maintenance

    • Kyle McCormick

  • “No New MFEs”

    • Kyle McCormick

  • Remote registry

    • Axim-provided registry? network of registries, different providers in different regions

    • Kyle McCormick

  • Local registry

    • This can definitely have multiple versions

    • Maksim Sokolskiy

  • Local cache. Two potential issues:

    • 1. ensure that it’s actually caching anything at all:https://discuss.openedx.org/t/npm-clean-install-in-mounted-directories-sh-super-slow-on-tutor-nightly-dev-with-mounted-edx-platform/12761/3

    • 2. version conflicts across MFEs may invalidate a shared cache

    • Dawoud Sheraz

• Other solutions (not currently following up on)

  • Pre-built image with some deps

    • Max has tried this

    • Install one mfe’s deps using previous mfe as a base

    • Used pnpm – can handle multiple different versions of package

      • pnpm didn’t work out of the box

    • pnpm , workspace for each mfe
