gRPC with Node.js

Transcript

1. gRPC with Node.js maybe it's time to put ReST to rest

3. What is gRPC?
4. gRPC - Developed by Google in 2015 - Uses HTTP/2 for transport - RPC stands for "remote procedure call" - Directly calls a method on the server as if it were a local object - Uses protobuf as IDL - Interoperable among languages
6. RPC is NOT new
7. JRMI - Java Remote Method Invocation Client Remote object Interface Stub Remote Object Implementation Remote object Interface Skeleton Client Server Implemented by the developer Implemented by JRMI
8. Protocol Buffers protobuf for the bffs <3
9. protobuf - OSS, Developed by Google - Mechanism for serializing structured data - Interface Definition Language - Requires compiling
10. message.proto
11. Compile time!
12. Outfile
13. message_pb.js
14. Generated Methods
15. Then we can just use
16. gRPC != Protobuf
17. Protobuf is universal_
19. gRPC is based on services_
20. Defining a service
21. Defining a service
22. Types of methods_
23. Unary
24. Server Streaming
25. Client Streaming
26. Bidirectional
27. Building the server with NodeJS
28. Install grpc
29. One small change
30. Load the protofile
31. Load the protofile "Database"
32. Implement the functions on the serverside
33. Implement the functions on the serverside
34. Start the server
35. Full code
36. Full code load
37. Full code load database
38. Full code load database implementation
39. Full code load database implementation run
40. Creating the client
41. Install grpc
42. Load the protofile
43. Add the service
44. Call it!
45. Full Code
46. DEMO
47. Problems - Docs are not very common - The initial development is more complex - Usage with TypeScript requires some work - It is a bit complicated to understand the idea and concepts
48. Advantages of gRPC - Way smaller due to binary transfer - HTTP/2 by default - Simple client calls - Lighter and supports a lot of calls - Supports streaming both in client and server - Protobuf standardizes the message exchange
49. Comparison
