> compatible mode
compatible mode are supported in fory js, there are lots of compatible tests
in javascript/test/crossLanguage.test.ts, which you can take as reference. For
example:
```javascript
test("test_skip_id_custom", () => {
const fory1 = new Fory({
compatible: true
});
@Type.ext(103)
class MyExt {
id: number = 0;
}
fory1.registerSerializer(MyExt, {
write: (value: MyExt, writer: BinaryWriter, fory: Fory) => {
writer.writeVarInt32(value.id);
},
read: (result: MyExt, reader: BinaryReader, fory: Fory) => {
result.id = reader.readVarInt32();
}
});
// Define empty wrapper for deserialization
@Type.struct(104)
class Empty { }
fory1.registerSerializer(Empty);
const fory2 = new Fory({
compatible: true
});
// Define Color enum
const Color = {
Green: 0,
Red: 1,
Blue: 2,
White: 3,
};
fory2.registerSerializer(Type.enum(101, Color));
@Type.struct(102, {
id: Type.varInt32()
})
class MyStruct {
id: number = 0;
}
fory2.registerSerializer(MyStruct);
fory2.registerSerializer(MyExt, {
write: (value: MyExt, writer: BinaryWriter, fory: Fory) => {
writer.writeVarInt32(value.id);
},
read: (result: MyExt, reader: BinaryReader, fory: Fory) => {
result.id = reader.readVarInt32();
}
});
@Type.struct(104, {
color: Type.enum(101, Color),
myStruct: Type.struct(102),
myExt: Type.ext(103)
})
class MyWrapper {
color: number = 0;
myStruct: MyStruct = new MyStruct();
myExt: MyExt = new MyExt();
}
fory2.registerSerializer(MyWrapper);
// Deserialize empty from Java
let cursor = 0;
const deserializedEmpty = fory1.deserialize(content.subarray(cursor));
cursor += fory1.binaryReader.readGetCursor();
expect(deserializedEmpty instanceof Empty).toEqual(true);
// Create wrapper object
const wrapper = new MyWrapper();
wrapper.color = Color.White;
wrapper.myStruct = new MyStruct();
wrapper.myStruct.id = 42;
wrapper.myExt = new MyExt();
wrapper.myExt.id = 43;
// Serialize wrapper
const serializedData = fory2.serialize(wrapper);
writeToFile(serializedData as Buffer);
});
