Björn Harrtell ef76b5ece4 [TS/JS] Entry point per namespace and reworked 1.x compatible single file build (#7510)
* [TS/JS] Entry point per namespace

* Fix handling of outputpath and array_test

* Attempt to fix generate_code

* Fix cwd for ts in generate_code

* Attempt to fixup bazel and some docs

* Add --ts-flat-files to bazel build to get bundle

* Move to DEFAULT_FLATC_TS_ARGS

* Attempt to add esbuild

* Attempt to use npm instead

* Remove futile attempt to add esbuild

* Attempt to as bazel esbuild

* Shuffle

* Upgrade bazel deps

* Revert failed attempts to get bazel working

* Ignore flatc tests for now

* Add esbuild dependency

* `package.json` Include esbuild

* `WORKSPACE` Add fetching esbuild binary

* Update WORKSPACE

* Unfreeze Lockfile

* Update WORKSPACE

* Update BUILD.bazel

* Rework to suggest instead of running external bundler

* Add esbuild generation to test script

* Prelim bundle test

* Run test JavaScriptTest from flatbuffers 1.x

* Deps upgrade

* Clang format fix

* Revert bazel changes

* Fix newline

* Generate with type declarations

* Handle "empty" root namespace

* Adjust tests for typescript_keywords.ts

* Separate test procedure for old node resolution module output

* Fix rel path for root level re-exports

* Bazel support for esbuild-based flatc

Unfortunately, we lose typing information because the new esbuild method
of generating single files does not generate type information.

The method used here is a bit hack-ish because it relies on parsing the
console output of flatc to figure out what to do.

* Try to fix bazel build for when node isn't present on host

* Auto formatting fixes

* Fix missing generated code

Languages known issues

Python

  • Assert the type required in your server/client since python is able to receive Bytes array or utf8 strings.
def SayHello(self, request, context):
    # request might be a byte array or a utf8 string

    r = HelloRequest.HelloRequest().GetRootAs(request, 0)
    reply = "Unknown"
    if r.Name():
        reply = r.Name()
    # Issues might happen if type checking isnt present.
    # thus encoding it as a `reply.decode('UTF-8')`
    return build_reply("welcome " + reply.decode('UTF-8'))

This can be prevented by making sure all the requests coming to/from python are Bytes array

def say_hello(stub, builder):
    hello_request = bytes(builder.Output())
    reply = stub.SayHello(hello_request)
    r = HelloReply.HelloReply.GetRootAs(reply)
    print(r.Message())

Go

  • Always requires the content-type of the payload to be set to application/grpc+flatbuffers

example: .SayHello(ctx, b, grpc.CallContentSubtype("flatbuffers"))
