+As you might have noticed, `pbjs` is also capable of generating static code. For example

+```
+$> pbjs -t static-module -w commonjs -o compiled.js file1.proto file2.proto

+
+will generate static code for definitions within `file1.proto` and `file2.proto` to a CommonJS module `compiled.js`, which then can be used with just the [minimal runtime](https://github.com/dcodeIO/protobuf.js/tree/master/dist/runtime).

 **ProTip!** Documenting your .proto files with `/** ... */`-blocks or (trailing) `/// ...` lines translates to generated static code.

+Picking up on the example above, the following not just generates static code to a CommonJS module `compiled.js` but also its respective TypeScript definitions to `compiled.d.ts`:
+
+```
+$> pbjs -t static-module -w commonjs -o compiled.js file1.proto file2.proto
+$> pbts -o compiled.d.ts compiled.js
+```
+
+Additionally, TypeScript definitions of static modules are compatible with reflection, as long as the following conditions are met:
+
+1. Use `SomeMessage.create(...)` instead of `new SomeMessage(...)` because reflection objects do not provide a constructor.
+2. Types, services and enums must start with an uppercase letter to become available as properties of the reflected types as well (i.e. to be able to use `MyMessage.MyEnum` instead of `root.lookup("MyMessage.MyEnum")`).
+3. When using a TypeScript definition with custom code, `resolveAll()` must be called once on the root instance to populate these additional properties (JSON modules do this automatically).
+
+For example, the following generates a `bundle.json` and a `bundle.d.ts`, but no static code:
+
+```
+$> pbjs -t json-module -w commonjs -o bundle.json file1.proto file2.proto
+$> pbjs -t static-module file1.proto file2.proto | pbts -o bundle.d.ts -

+### On reflection vs. static code
+
+While using .proto files requires the [full library](https://github.com/dcodeIO/protobuf.js/tree/master/dist) (about 18.5kb gzipped) or JSON just the [noparse library](https://github.com/dcodeIO/protobuf.js/tree/master/dist/noparse) (about 15.5kb gzipped), pretty much all code but the relatively short descriptors is shared and all features including reflection and the parser are available.
+
+Static code, on the other hand, requires just the [minimal runtime](https://github.com/dcodeIO/protobuf.js/tree/master/dist/runtime) (about 5.5kb gzipped), but generates additional, albeit editable, source code without any reflection features.
+
+There is no significant difference performance-wise as the code generated statically is pretty much the same as generated at runtime and both are largely interchangeable as seen in the previous section.

 The package includes a benchmark that tries to compare performance to native JSON as far as this is possible. On an i7-2600K running node 6.9.1 it yields:
