Fix issues in TypeScript getting started example code #1374

mickdekkers · 2020-08-02T09:48:40Z

Which problem is this PR solving?

Problems in the TypeScript getting started example:

The use of a non-generic type as generic
Gaps in the TypeScript type coverage

Short description of the changes

Change the use of Metric<BoundCounter> to Counter (Metric is no longer generic, so this didn't compile)
Add @types/node so TypeScript can compile app.ts which uses process.env
Add @types/express so the express API is no longer any
Define the the result type of the countAllRequests function as an Express RequestHandler so that req, res, and next are no longer any

I noticed 2 more things while I was following the guide:

typescript is not a (dev)dependency, so the npm scripts don't work (well, they might inside the opentelemetry-js repo due to phantom dependency).
the README.md of the guide explains step by step how to arrive at the state in the folder and includes code samples and npm install commands. We'll want to update the readme to keep it in sync.

I'll try to update this PR soon, probably tomorrow.

getting-started/ts-example/monitoring.ts

 import { PrometheusExporter } from '@opentelemetry/exporter-prometheus';
+import { RequestHandler } from "express";


interesting is that this line didn't cause the build to fail on linting, as there should be single quotes.

I don't think the getting started guide is linted

@mickdekkers can you please change this line to use single quotes ?

Sure thing, I'll change it to single quotes 👍

FYI, this isn't consistent in the getting started guide: tracing.ts uses both single and double quotes and app.ts uses double quotes

Like I said, the guide isn't linted. Since the guide rarely changes, I think it isn't necessarily a problem. Let's make these small quote changes and merge this. Eventually, the guide will need to be rewritten for the sdk package, and maybe we should start linting it then.

I am going to merge this, with a follow up to lint the getting started guide
