A micro-frontend is an architectural pattern for web development, where independently developed frontends are composed into a greater whole.[1] It is analogous to a microservices approach but for client-side single-page applications written in JavaScript.[2] It is a solution to de-composition and routing for multiple front-end applications.[3]
Micro frontends (MFE) can be built using the following approaches:
Companies that use micro frontends are Canonical, IKEA, Scania AB, Spotify, etc.[4]
For Webpack this concept is referred to as module federation.[5]
