3. Compare how to call the methods based on gRPC and REST API side-by-side, e.g. in a Table format as shown below.
| Functions | gRPC | REST API |
|---|---|---|
| List books | client.list({}, function(error, books){ printResponse(error, books);}); | node client.js list |
| Insert books | client.insert(book, function(error, empty) { printResponse(error, empty);}); | node client.js insert |
| Get books | client.get({ id: parseInt(id) }, function(error, book) { printResponse(error, book); }); | node client.js get |
| Delete books | client.delete({ id: parseInt(id) }, function(error, empty) { printResponse(error, empty); }); | node client.js delete |
| Watch books | call.on(‘data’, function(book) { console.log(book); }); | - |
The main differences between REST API and gRPC is the format of the payload. REST API use json as the format for messages but gRPC use protobuf messages that usually send as binary which make it a lot faster and more efficient.
5. What is the benefits of introduce interface in front of the gRPC and REST API of the book services.
It provides multiple inheritance so that a class can achieve total abstraction and reduce coupling between classes. Moreover, it also provided user transparency.
6. Based on the introduced interface, compare how to call the methods based on gRPC and REST API side-by-side, e.g. in a Table format as shown below.
| Functions | gRPC | REST API |
|---|---|---|
| List books | node interface.js grpc list | node interface.js rest list |
| Insert books | node interface.js grpc insert <title> | node interface.js rest insert <title> |
| Get books | node interface.js grpc get | node interface.js rest get |
| Delete books | node interface.js grpc delete | node interface.js rest delete |
| Watch books | Node interface.js grpc watch | - |
