* [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 Co-authored-by: Derek Bailey <derekbailey@google.com> Co-authored-by: James Kuszmaul <jabukuszmaul+collab@gmail.com>

Args:
|

name: Name of the generated ts_library rule.
|
|
srcs: Source .fbs file(s).
|
|
deps: Other flatbuffer_ts_library's to depend on. Note that currently

|
you must specify all your transitive dependencies manually.
|
|
include_paths: Optional, list of paths the includes files can be found in.
|
|
flatc_args: Optional list of additional arguments to pass to flatc
|
|
(e.g. --gen-mutable).
|
|
visibility: The visibility of the generated cc_library. By default, use the
|
|
default visibility of the project.
|
|
compatible_with: Optional, The list of environments this rule can be built
|
|
for, in addition to default-supported environments.
|
|
restricted_to: Optional, The list of environments this rule can be built
|
|
for, instead of default-supported environments.

|
target_compatible_with: Optional, The list of target platform constraints
|
|
to use.
|
|
gen_reflections: Optional, if true this will generate the flatbuffer
|
|
reflection binaries for the schemas.

|
package_name: Optional, Package name to use for the generated code.
