Add export to GasPlugin for exporting its definition to dist/index.d.ts

[Tei1988]

Hello.

When I have written an esbuild configuration in TypeScript, I could not import { GasPlugin } from esbuild-gas-plugin package because of no types exported in dist/index.d.ts. So I add export keyword to GasPlugin.

In my local machine, it seems to work.

Anyway, thank you for publish this plugin.

Thanks for using this plugin and contribution!

Does it work if use import GasPlugin from 'esbuild-gas-plugin instead of import { GasPlugin } from 'esbuild-gas-plugin ?

// index.ts
import GasPlugin from 'esbuild-gas-plugin'

console.log(GasPlugin)

> tsc && node dist/index.js

{ GasPlugin: { name: 'gas-plugin', setup: [Function: setup] } }

my tsconfig.json

{
  "compilerOptions": {
    "target": "es2016",
    "module": "commonjs",
    "rootDir": "./src/",
    "outDir": "./dist/",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "skipLibCheck": true
  }
}

Thank you for reply.

No, it does not work.

I tried to build using this script below:

import * as esbuild from 'esbuild'
import GasPlugin from 'esbuild-gas-plugin'

esbuild.build({
  entryPoints: ['src/main.ts'],
  bundle: true,
  outfile: 'dist/Code.gs',
  plugins: [GasPlugin]
})

and got this output below:

$ ts-node ./esbuild.ts
/src/node_modules/ts-node/src/index.ts:820
    return new TSError(diagnosticText, diagnosticCodes);
           ^
TSError: ⨯ Unable to compile TypeScript:
esbuild.ts:8:13 - error TS2769: No overload matches this call.
  The last overload gave the following error.
    Type 'typeof import("/src/node_modules/esbuild-gas-plugin/dist/index")' is missing the following properties from type 'Plugin': name, setup

8   plugins: [GasPlugin]
...

This error seems that the type of GasPlugin is missing.

By the way, I found that my change is wrong becasuse of the compiled javascript is not work. So I will close this PR.

I supposed that using export = { GasPlugin } instead of exports.GasPlugin = GasPlugin will resolve this situation. Could I send new PR?
