Protoc compilation

OS- Windows-10 64-bit

  1. Install Protoc
  2. Download ProtoBuf Compiler (protoc) protoc-3.8.0-win64.zip . - currently 3.8.0
  3. Unzip protoc to a location. Say C:/protobuf/protocWin
  4. Append Environment Variable PATH with C:/protobuf/protocWin/bin
  5. Get a .proto file (say, abc.proto). Place it in a directory. (E.g. C:/workingDir/)
  6. Compile the .proto file and generate import files (Closure Imports)
    1. Open command prompt/ powershell.
    2. Go to C:/workingDir/
    3. Type the following for creating separate import files for each message in the Proto file
      1. protoc --js_out=,binary:./output abc.proto
    4. Or, for a single .js file
      1. protoc --js_out=library=combined/lib,binary:./output abc.proto
    5. This will create lib.js in C:/workingDir/output/combined/
    6. Or, for Common Imports,
      1. protoc --proto_path=src --js_out=import_style=commonjs,binary:combined/lib src/abc.proto
  7. Use these generated files as required. See the project structure.
