A library for serializing a thrift model into bytes.
- Add the library as a depency by adding
"com.gu" %% "thrift-serializer" % "2.1.1"
to your applications libraryDepencies.
- You can then use ThriftSerializer in your application:
import com.gu.thrift.serializer.ThriftSerializer
object myObject extends ThriftSerializer {
def myMethod(thriftObject: MyThriftObject): Unit = {
val bytes = serializeToBytes(thriftObject)
//Do something with bytes
}
}
- You can use the ThriftDeserializer like this:
MyDeserializer.deserialize(buffer).map(myEvent => {
// process the event
}
def myMethod(thriftObject: MyThriftObject): Unit = {
val bytes = serializeToBytes(thriftObject)
//Do something with bytes
}
If there is no compression type recorded in the bytes you wish to deserialize or if you don't want these to be included when serializing a thrift object, you can set the last arguments of the function calls to true. They are false by default.
MyDeserializer.deserialize(buffer, true).map(myEvent => {
// process the event
}
def myMethod(thriftObject: MyThriftObject, true): Unit = {
val bytes = serializeToBytes(thriftObject)
//Do something with bytes
}
-
The library is published to Maven Central. To publish, register to Sonatype and get added to Guardian projects.
-
Run sbt release. You will be asked about what version you want the release to be during the release process, you do not have to update it manually.
- Install using npm
npm install --save thrift-serializer
in your application or lambda you can decode messages
var Message = require('your-thrift-model');
var serializer = require('thrift-serializer');
serializer.read(Message, bytes, function (err, msg) {
console.log(msg);
});
or encode them
var Message = require('your-thrift-model');
var serializer = require('thrift-serializer');
var message = new Message({
someData: ''
});
serializer.write(message, serializer.Compression.Gzip, function (err, bytes) {
// do something with your bytes, e.g. convert the buffer into a base64 string
console.log(bytes.toString('base64'));
});
