Generated TypeScript imports non-existent files when unions are used in imported file(s)

[CS-Labs]

This is a follow-on to issue #4637 which still appears to exist in residual forms.

The issue described in issue 4637 still occurs when unions are being used in one of the files being imported. (Using the latest version of flatc 1.12.0).

Example:

With the following flatbuffer files:
main.fbs

include "example.fbs";

namespace schemas;

table Main {
  example:Example;
}

root_type Main;

example.fbs

include "nested.fbs";

namespace schemas;

table Example {
  nested:NestedWrapper;
  foo:int;
}

root_type Example;

nested.fbs

namespace schemas;

table NestedA {
  a:bool;
  b:byte;
}
table NestedB {
  c:bool;
  d:byte;
}
union NestedUnion {
    NestedA,
    NestedB,
}
table NestedWrapper {
    message: NestedUnion;
}

root_type NestedWrapper;

Run the command:

flatc -o out/ts --ts --gen-all --no-fb-import ./main.fbs

And the output will be:

// automatically generated by the FlatBuffers compiler, do not modify

import * as NS2526511929974982885 from "./nested_generated";
export namespace schemas { 
export import NestedB = NS2526511929974982885.schemas.NestedB; }
export namespace schemas { 
export import NestedA = NS2526511929974982885.schemas.NestedA; }
/**
 * @enum {number}
 */
export namespace schemas{
export enum NestedUnion{
  NONE= 0,
  NestedA= 1,
  NestedB= 2
}};
.....
....
....

What is expected? The flatbuffer definitions should be self contained within a single generated file.

Let me know if I need to provide any additional information.

Thanks

The issue doesn't seem to exist in the new TS support. Can you check current master?

Hey,

It appears like valid TypeScript is being generated on the master version (c0be1cb).

For reference, I regenerated things with:

flatc -c -o out main.fbs --ts --gen-all

Is the next official release of this library going to be 2.0? If so is there an estimated timeframe for this release?

Thanks
