micro-lc is an open source micro-frontend orchestrator for building flexible, multi-tenant frontend applications. And much more!

Tip: use the official playground to try micro-lc immediately.

An introduction about micro frontend and how micro-lc works:

micro-lc is shipped as an ES module CDN bundle and can be imported in any HTML page. Moreover, a dockerized webserver is available on Docker Hub.

Read the docs to learn how you can use micro-lc in your next project!

This repository is made of 5 subpackages. The dependencies can be sketched as follows:

  `interfaces`
           |
    `composer`
           |
`orchestrator` `iconic`
           |    |
          `layout`

to build the packages there's a script which can be invoked after install as

yarn initialize [OPTIONS]

where OPTIONS are

1. -c or --cleanup
2. one of the subpackages: interfaces, iconic, composer, orchestrator, and layout (default)

By using cleanup you require initialize to trash anything in the dist, node_modules, and coverage directories. By choosing one subpackage, initialize will build up to that one.

To build the repository disregarding previous actions run:

yarn initialize --cleanup

Yarn allows to invoke scripts onto subpackages in a workspaces environment. Such commands might become soon verbose since to build a subpackage the command would be like:

yarn workspace @micro-lc/orchestrator build

hence we enforced some shortcuts:

1. workspace @micro-lc/interfaces -> i
2. workspace @micro-lc/iconic -> c
3. workspace @micro-lc/composer -> m
4. workspace @micro-lc/orchestrator -> o
5. workspace @micro-lc/layout -> l

hence the command above would become:

yarn o build

To run tests ensure some CommonJS to ESM conversion on dependencies by running

yarn prepare-test

then simply run

yarn test

or

yarn coverage

layout is a webcomponents repository and provides a storybook environment. Remind to build dependencies as prompted before and then run:

yarn l storybook

A local playground is also available. Run:

yarn playground

to start the playground, and:

yarn playground-stop

to stop it.

To create a tag, a custom script is provided. Given the library/package you'd like to tag:

• orchestrator
• composer
• layout
• iconic
• interfaces

just run

yarn bump <PACKAGE> [major|minor|patch|<VERSION>]

which will:

1. update the changelog moving the unreleased entries to the tagged version
2. create the appropriate tags for npm libraries and docker containers

Notice that orchestrator release, on tag, both the npm library and a docker container, hence carries 2 tags simultaneously.
