this PoC will allow us to create blog posts, and is composed with:
- a graphQL server, in front of the client as our unique BFF entry point. Its role is mainly to validate input data (required / optional fields, type, …) and filter output data. The validation here is important since required & optional fields have been dropped from proto3. It also acts as a client to the gRPC micro-service.
- a gRPC server, to perform all functional operations. Here to create and list some blog posts.
To run the PoC, install NodeJs, Mongodb and Git, and launch the following commands:
git clone [email protected]:svengau/grpc-graphql-sample.git
cd post-api && npm start
cd graphql-api && npm start
🚀 Server ready at http://localhost:4000/graphql
and run the following query:
mutation {
addPost(data: { title: "helloooo" }) {
message
result { _id title body }
}
}
```
