[Question] need some packages if using with TypeScript

[mmktomato]

I found I need to install @types/node and @types/debug to build an application which uses Playwright and TypeScript.

Versions

• Playwright: 0.11.1
• Node: v10.18.1
• OS: Ubuntu 18.04

What I did

$ npm init -y
$ npm install -S playwright
$ npm install -D typescript
$ echo "import * as playwright from 'playwright';" > index.ts
$ npx tsc --outDir ./dist --lib es2015,dom ./index.ts

Then I met some errors.

node_modules/playwright-core/lib/frames.d.ts:17:23 - error TS2688: Cannot find type definition file for 'node'.

17 /// <reference types="node" />
                         ~~~~

node_modules/playwright-core/lib/frames.d.ts:88:54 - error TS2503: Cannot find namespace 'NodeJS'.

88     readonly _networkIdleTimers: Map<LifecycleEvent, NodeJS.Timer>;
                                                        ~~~~~~
\node_modules/playwright-core/lib/helper.d.ts:17:23 - error TS2688: Cannot find type definition file for 'debug'.

17 /// <reference types="debug" />
                         ~~~~~

(snip)

Solution?

tsc goes well if I install @types/node and @types/debug.

$ npm install -D @types/node @types/debug
$ npx tsc --outDir ./dist --lib es2015,dom ./index.ts
$ cat ./dist/index.js 
"use strict";
exports.__esModule = true;

Question

Should this be documented in somewhere?
If so, could you point me where to write? I will send a PR.
(I think Code Transpilation Issues in troubleshooting.md would be good.)

Thanks for the heads up. Currently we are using the d.ts files that typescript generates for us, but this is intended as a temporary measure. Generating our own d.ts which filter our private methods should fix this. #6

I understand. Thanks for hard working!
