[BUG] playwright-core has no main entry

[mxschmitt]

Context:

• Playwright Version: 1.1.1
• Operating System: MacOS
• Node version: 14
• Browser: playwright-core

Describe the bug

The playwright-core package does not contain anymore a valid index.js / entrypoint.

1.0.2: https://unpkg.com/playwright-core@1.0.2/index.js <-- expected
1.1.0: https://unpkg.com/playwright-core@1.1.0/index.js <-- actual

Is this expected? Because it's still referenced in the package.json>main.

Workaround:

"playwright-core": "npm:playwright-chromium@1.1.1",

We cannot currently use playwright-core. Repro:

const { devices } = require("playwright-core");
console.log("devices", devices);

Error:

internal/modules/cjs/loader.js:331
      throw err;
      ^

Error: Cannot find module '/Users/jon/dev/examples/pw-core/node_modules/playwright-core/index.js'. Please verify that the package.json has a valid "main" entry

What is the status of this? We are using playwright-core with https://github.com/JupiterOne/playwright-aws-lambda and multiple users have now reported this issue. JupiterOne/playwright-aws-lambda#9.

Thoughts @pavelfeldman @dgozman @aslushnikov @yury-s?

@austinkelleher @jperl Ah! Sorry for this! I've submitted a PR to address this.

While we are here - can you please share how exactly you use playwright-core? It'll be very helpful
to understand your use cases.

@aslushnikov Huge thanks for the quick follow-up! Love what you all are doing with Playwright

@aslushnikov Whoops submitted too soon...We are running Playwright on AWS Lambda by shipping a chrome binary with the package (we don't want to auto-install at runtime). Here is the usage: https://github.com/JupiterOne/playwright-aws-lambda/blob/master/src/chromium.ts#L102.

Also leveraging some TypeScript typings e.g. https://github.com/JupiterOne/playwright-aws-lambda/blob/master/src/chromium.ts#L8
