+# Migrating to multi_rules
+
+Previously, the `typescript_proto_library` rule would also build grpc-web outputs automatically.
+
+This is now split into multiple rules to align with other languages:
+- `typescript_proto_library` for outputting protobuf messages files (_pb.d.ts, _pb.js)
+- `typescript_grpc_node_library` for outputting protobuf service and client files (_grpc_pb.d.ts, _grpc_pb.js); supports both grpc and grpc-js requires
+- `typescript_grpc_web_library` for outputting protobuf service and client files (_pb_service.d.ts, _pb_service.js)
+
+To keep the same behavior, add to your definition:
+```python
+# Before:
+typescript_proto_library(
+    name = "test_ts_proto",
+    proto = ":test_proto",
+)
+
+# After:
+typescript_proto_library(
+    name = "test_ts_proto",
+    proto = ":test_proto",
+)
+typescript_grpc_web_library(
+    name = "test_ts_grpc_web",
+    proto = ":test_proto",
+)
+```
