micro-app is a micro front-end framework from JD that renders sub-applications via webcomponent-like custom elements, so a base app can embed any framework's app with a single <micro-app> tag and one start() call. It bundles a JS sandbox, style and element isolation, preloading, resource address completion, a plugin system, and cross-app data communication.

Use cases

• migrate a large monolithic frontend to micro frontends incrementally
• embed a react app inside a vue base application
• run multiple frontend frameworks together in one page
• isolate javascript and css between independently deployed frontend apps
• integrate legacy frontend apps into a new codebase with minimal changes
• adopt micro frontends with the lowest possible integration cost
• split a frontend into independently developed and deployed sub-applications

When to choose

• You want a low-effort micro frontend setup - one npm package, one component tag, no invasive changes to sub-apps
• Your base and sub applications use different frameworks or versions and need framework-agnostic composition
• You need sandboxing, style/element isolation, preloading, and data communication built in rather than hand-rolled

When to avoid

• You are building a single small application with one team and no need for independent deployment
• You prefer build-time code sharing like webpack Module Federation over runtime embedding of whole apps
• You need only shared UI components rather than full independent micro applications
