contextnavidadon A ChatGPT mistake cost us $10k

> Our project was originally full stack NextJS but we wanted to first migrate everything to Python/FastAPI

This is the eye opener for me, how is a startup justifying a re-write when they don't even have customers?

Take a look at Posteo. Seem to have a similar philosophy as Mullvad.

contextnavidadon TypeScript: Branded Types

> because you can't pass a name string as an argument that is expected to be an email address

Unless you accidentally create the wrong branded type? Which is as likely as disordered arguments.

As you stated, tests should cover this case trivially, I don't see the value in added type complexity.

contextnavidadon PM2: Production Process Manager with a Built-In Load Balancer

Had good experiences with PM2, however be cognizant of it's copy left license. We have found it redundant with the likes of Kubernetes.

contextnavidadon UK middle classes 'struggling despite incomes of up to £60k a year'

Midlands is the way to go honestly, great transport links to the whole country, great nature, very cheap living.

You're a little off on the average UK wage. It's around £34k now.

contextnavidadon Ask HN: Is Express still "de-facto" for building Node back ends?

> async middleware not handling errors properly thing though

Can you expand on this? Error handling in middleware is pretty well documented.

contextnavidadon Semver violations are common, better tooling is the answer

Upgrade everything you need with a commit per upgrade, then if something breaks `git bisect` to find the troublesome package.

And read release notes for everything you upgrade too.

contextnavidadon No Lodash

We used `cloneDeep` heavily at a previous role, it isn't particulary fast - so be careful if you cloning very big objects (1mb+). There are faster options out there such as https://github.com/davidmarkclements/rfdc or even https://developer.mozilla.org/en-US/docs/Web/API/structuredC...

contextnavidadon A: A CLI tool to generate code snippets from GPT3 written in Rust

Looks like you need an env var `OPENAI_API_KEY` for this to work. Strange that it is not documented at all.

Also they could have provided an actual error rather than letting it panic!

contextnavidadon Ask HN: How Long Does a Deployment Take at Your Company

From the deployment stage of the pipeline to live traffic hitting the new code, probably a couple of minutes. Limited by image pulls, application startup time and K8s rollout strategy.

I have my linting setup to force a base on `parseInt`, for the extra characters I do feel it's worth it for the safety.

The extra parentheses is just habit from Prettier formatting :)

It's great to see other JS runtimes progressing, I have a continued frustration with the lack of decent TS tooling and ESM support in Node.js.

Jest and Mocha both do not support ESM very well out of the box and there is an expectation that you are using babel to transpile to CommonJS for everything to work nicely. (See Jest's _experimental_ support for ESM mocking!). Node.js is only starting to build out a testing framework, and it has a way to go yet until it has any level of feature parity with the established libraries.

Then you have the naive assumption that any package written in JS works with TS. Which is true, they do work, but the missing types will always lead you to look for a TS-first alternative. A good example of this is Joi vs Zod for validation, with the latter performing type inference based on your validation parameters, which is great. But it really does feel like you have a subset of a package ecoystem lurking on NPM.

I am not that confident Deno is the answer, but I would say those are my biggest frustration writing production grade JS/TS code today.

It passes the value and index to `parseInt`, where the 2nd argument is `base`. So it does not return `[10, 10, 10]` as you'd expect. It returns `[10, NaN, 2]` instead.

You have to do `['10', '10', '10'].map((val) => parseInt(val, 10));` to get the "expected" output. In addition, you should always provide `base` to `parseInt` otherwise it has it's own interpretation infered by the value you give it.
