No nonsense protobuf schema parser written in Javascript
npm install protobuf-schemaNo nonsense protobuf schema parser written in Javascript
`` js`
npm install protobuf-schema
First save the following file as example.proto
`
message Point {
required int32 x = 1;
required int32 y=2;
optional string label = 3;
}
message Line {
required Point start = 1;
required Point end = 2;
optional string label = 3;
}
`
The run the following example
` js
var fs = require('fs')
var schema = require('protobuf-schema')
// pass a buffer or string to schema.parse
var sch = schema.parse(fs.readFileSync('example.proto'))
// will print out the schema as a javascript object
console.log(sch)
`
Running the above example will print something like
` js`
