#TypeScript

Now in @rinkkasatiainen's session on
functional programming with #TypeScript. #SoCraTes2022

Tip for the #AWSCDK #TypeScript users: In order to ensure that the outputs of
your CloudFormation Stacks are typed properly, you can use this technique.
https://github.com/coderbyheart/typesafe-stack-outputs-cdk#readme

Really happy to have #rustlang in my #TypeScript toolchain. @swc/jest is so fast
it's really a joy to write tests:
https://github.com/distributeaid/needs-assessment-storage/pull/63/commits/e0d674b8e5ca0ef239e1102fccd0111cbed1fb91#diff-ca11e937780ce79128e2d43440e1168009bad2a12cc7313e6e782f5ea28326a9R207-R230

@kolencherry Sorry, no dice in #TypeScript:

I have a #TypeScript mapped type problem I don't know how to tackle:

I am looking for a way to turn this JS object: { a: true, b: false } into this
TS type: { a: string, b?: string }

Any pointers?

Are you like me drinking the @ReproBuilds
kool aid and configure your JavaScript projects using environment variables ALL
THE TIME? I use a little helper which complains if they are missing and
otherwise plays nice with #TypeScript:
https://www.npmjs.com/package/@nordicsemiconductor/from-env

#typescript 4.5 has been released and now it fails to compile code because of
TS2589: Type instantiation is excessively deep and possibly infinite.

Some combination of fp-ts, typebox is causing this now.

I am now investing more time in outreach efforts to universities, and I also
have hired a student (who is studying electrical engineering right now) and
started to teach them the necessary skills to build #serverless #iot cloud
solutions using #JavaScript / #TypeScript.

Come work with me in one of these amazing places in Europe, where
@NordicTweets has R&D offices, on the
technology that enables the next billion devices to connect to the cloud. 🌩️
#cellularIoT powered by #serverless, #typescript, and #opensource:

So many improvements to #TypeScript center around classes. I've stopped using
classes in TypeScript ~2 years ago and don't miss anything.
https://devblogs.microsoft.com/typescript/announcing-typescript-4-3-rc/

About the process: we are looking for people who love to make technology more
accessible, through great examples and documentation. That's why we try to
figure out your skills as a cloud engineer by checking for your #JavaScript and
#TypeScript skills in a coding challenge.

I already use ajv to do runtime validation but just learned from @arrowoodtech
about https://github.com/sinclairzx81/typebox which simplifies creating the
#TypeScript types for the consuming code after validation passes. #NodeCongress

Migrating to #AWS SDK v3 for JavaScript

In this blog post I will summarize my findings when migrating the AWS flavour of
Bifravst to version 3 of the AWS SDK.

https://coderbyheart.com/aws-sdk-v3

#cloudnative #typescript

First-class #TypeScript coming to version 3 of the AWS SDK:
https://aws.amazon.com/blogs/developer/first-class-typescript-support-in-modular-aws-sdk-for-javascript/
via @awscloud

It's really annoying that @Azure is not keeping
their NPM release in sync somehow.

I cannot use @azure/arm-deviceprovisioningservices and @azure/arm-appservice at
the same time without #TypeScript complaining because they depend on different
versions of @azure/ms-rest-nodeauth.

It gets a little painful to keep CRA and #TypeScript working nicely together, so
I am really thinking about trying on of the new build-free tools like @pikapkg's
Snowpack or Vite.js...

https://ts-ast-viewer.com/ by
@DavidSherret is amazing: it shows the
compiler API calls needed to created a certain #TypeScript code:

#typescript generator problem: how can I generate a type reference node with
array access?

#TypeScript 4 Beta is here and brings amongst others typing of variadic function
arguments!
https://devblogs.microsoft.com/typescript/announcing-typescript-4-0-beta/

Yes, #TypeScript should solve these ambiguities of #JavaScript.

To prevent unintended behaviour like this I have the
https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/strict-boolean-expressions.md
eslint rule enabled, which will detect this and one needs to explicitly test for
undefined or 0. https://twitter.com/boennemann/status/1275855456360153089

CodeArtifact is a new npm compatible package registry from AWS:

I've started to implement an SDK for a REST API from scratch in #TypeScript
using #fp-ts, and I like how simple the interaction with the client is, even for
following links or recursive fetching pages:
https://github.com/distributeaid/flexport-sdk-js

Hooks, because Classes in JavaScript are useless cruft.

The biggest gamechanger for #React development is using #TypeScript, so THAT as
well. https://twitter.com/ASpittel/status/1248314908535656448

Yesterday I ran into a #TypeScript challenge which I could not solve. I want a

My equivalent is running compiled #TypeScript but forgetting that I added source

@StandardJS The #TypeScript linting landscape
is moving a little right now, TSLint is getting replaced by ESLint:
https://github.com/palantir/tslint/issues/4534 - so it will be a while until
this stabilizes.

Have you tried: https://github.com/standard/standard#typescript ?

Did somebody already talk / write about replaced tools like immer.js /
immutable.js with #TypeScript's readonly keyword (which is availabel for arrays
since 3.4 as well)?

https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-4.html

I blogged about the latest (and greatest?) way I could come up with to publish

#TypeScript 3.4 is here and it adds readonly for array/set method parameters
(👍) and a refactoring helper for option objects (❤️)!
https://devblogs.microsoft.com/typescript/announcing-typescript-3-4/

HA!

I know use objects as arguments forever in #TypeScript to functions, because
this is always annoying:

const f1 = (arg1: string, arg2: boolean) => { // validate args, but must use
new name const _arg1 = v1(arg1); const _arg2 = v2(arg2); }

but this is cool:

I am getting more and more convinced that classes in #JavaScript or #TypeScript

Value Types: https://coderbyheart.com/value-types/ On runtime validation with

In 2019:

1. Frameworks and tools don’t last in #JavaScript. Don’t hold on to your current

2. #React will be the dominant framework.
3. You’ll need to learn #GraphQL.

Yesterday I started looking into generating API clients for JavaScript off a
OpenAPI 3 definition. Using the #TypeScript Compiler API the result is pretty
neat:

Another day where I want to shoot #TypeScript:

Post in the Tumblr Engineering blog comparing #Flow and #TypeScript:
https://engineering.tumblr.com/post/165261504692/flow-and-typescript/amp

Please, #TypeScript get out of my way, I know what I am doing. >

Why is #TypeScript killing my code here? [...Array(2)].map(() => 'f'); is
converted to Array(2).slice().map(function () { return 'f'; });

What annoys me about #TypeScript is that tslint and tsc are two separate things.
Why isn't tslint using tsc?

Should I add one more? #TypeScript and signature overloading is fun ;-)
