Question 1

How do I add authentication to a Feathers app?

Accepted Answer

Feathers doesn't include built-in authentication but provides the @feathersjs/authentication module and community plugins for OAuth or JWT. You'll need to install and configure these separately, following the Feathers guides for implementation.

Question 2

Feathers vs Express for building APIs?

Accepted Answer

Feathers offers integrated real-time support and a service-oriented architecture out of the box, while Express is more minimal and flexible. Choose Feathers for apps needing real-time capabilities, but Express if you prefer lightweight control without extra abstractions.

Question 3

Can I use Feathers with GraphQL?

Accepted Answer

Feathers doesn't have native GraphQL support, but you can integrate it using community plugins or build custom resolvers. It's primarily designed for REST and real-time APIs, so GraphQL requires additional setup and might not leverage all Feathers features.

Question 4

How to deploy a Feathers application to production?

Accepted Answer

Deploy like any Node.js app: use process managers like PM2, containerize with Docker, or host on platforms like Heroku or AWS. Ensure your hosting provider supports WebSockets for real-time functionality, and follow Feathers deployment guides for optimization.

Question 5

Does Feathers work with MongoDB or PostgreSQL?

Accepted Answer

Yes, Feathers has built-in adapters for MongoDB (e.g., feathers-mongoose) and PostgreSQL (e.g., feathers-knex), as part of its database agnostic design. You can easily switch between databases by configuring the appropriate adapter.

Question 6

Is Feathers good for microservices?

Accepted Answer

Feathers' service-oriented architecture makes it suitable for microservices, allowing services to be independently deployed. However, real-time communication between services might need additional tooling, and it's best for cohesive, full-stack apps rather than highly distributed systems.
