As React, Vue, Angular and other Frontend frameworks mature, more and more projects embrace them in production. It has reached a point where a project written in React wants to use Angular or Vue components (and vice versa). We will explore pragmatic ways to use components created using different frameworks in the same app. I am working on an Angular project for one of our clients. It recently acquired a company which is invested into React for few years. There is a plan to merge our products which has a lot of feature overlap. To use capabilities of existing teams, it was decided to use React components within Angular app. This is when we explored all possibilities of inter operations between frameworks. This talk will be case study of our work and what you can take away from it
