If you continue the topic of alternatives for ExpressJS, you can also try Ditsmod (I am the author of it). This framework is also inspired by Angular, but in my opinion it is easier to use then NestJS and better designed for modularity and scalability. In particular, Ditsmod has, in addition to modules with parameters, a system of extensions (aka plugins) that can depend on each other and initialize asynchronously. In addition, Ditsmod has such a concept as extensions groups, thanks to which you can have several extensions that do the same work (for example, there can be regular routes, and there can be routes for OpenAPI).

Ditsmod looks good, though I would argue a more direct comparison to Express would be fastify. Express.js vs Fastify - In-Depth Comparison of Node.js Frameworks
