use 'export type'

[MichaelTheriot]

Deno 1.5.0 includes a breaking change to enable the isolatedModules flag by default: https://github.com/denoland/deno/pull/8050

The following errors in mod.ts on Deno v1.5.0:

error: TS1205 [ERROR]: Re-exporting a type when the '--isolatedModules' flag is provided requires using 'export type'.

This re-exports types using export type to fix it.

Hi Michael,

Looks like the tests fail, though due to an unrelated problem (fails also on master now): appears like Deno decided to break imports with v in the name, but I'm not sure if I'm missing anything. Looks to me like the entire ecosystem would break 🤷‍♂️ I'm surprised this still works for you, perhaps due to cached sources?

I fixed the "v" imports and also upgraded to Deno 1.5.3 on master. I'm not getting the error you mention above.

Here is the minimal reproducible example I have.

main.ts:

import { connectPg } from 'https://deno.land/x/pgc4d/src/mod.ts';

console.log(connectPg);

$ deno --version
deno 1.5.3 (ab7b8ba, release, x86_64-pc-windows-msvc)
v8 8.7.220.3
typescript 4.0.5

$ deno run main.ts

I only get this error on 1.5.0+.

@MichaelTheriot 1.3.6 should work, thanks!
