RT @EffectTS_: At Effect Days, David Blass @ssalbdivad gave us a deeper understanding of the set theory at the heart of TypeScript and how….

Well it turns out that @EffectTS_’s learning curve is less steep than the “let’s fix garbage in production and barely understand why” curve.

Not to mention that Layer.scoped made it absolutely trivial to inject and reuse a single instance of Puppeteer across all HTTP API calls, ensuring the browser instance is properly closed when the Effect Platform HTTP Server shuts down.

We’ve just improved the performance of an app generating PDF files with Puppeteer by a factor of 10, going from ~30 secs to about 3. How?. Install @EffectTS_, then wrap code with Effect and add telemetry. Analyze spans, then add concurrency: true, Requests + caching. That’s it.

We’re super proud of you @c9antoine 👏🏻.
At Effect Days, Antoine Coulon @c9antoine talked about his journey of building a static analysis tool called @skott_npm using Effect-driven development, which combines the principles of test-driven and type-driven development. Link to the full video in the thread ⤵️

Can’t edit but it should read as "if it" obviously 🥸. Also I’m referring to: And the excellent:

The original essay that helped promises win over callbacks in the JavaScript ecosystem.

I would still use @EffectTS_ it it was full blown OOP with the same underlying guarantees that I get a lot less edge cases and a big boost in productivity. If you’re convinced @EffectTS_ is functional programming then you’re probably "missing the point of Effects".

I’m a much better programmer today than I was 2.5 years ago, after 25+ years of programming and 12 professionally. Why? @EffectTS_ taught me to deeply care about problems I was underestimating, which all applications face no matter which language they’re written in.

Using @EffectTS_ is one of these rare "high reward / low risk" bets:. - if Effect fails, congratulations you’re now highly skilled at TypeScript and that’s still very valuable on the market.- if Effect succeeds, congratulations you’re now highly skilled at both and very valuable.

Effect is a Domain Specific Language (DSL) embedded in TypeScript. In that sense only, it is a "new language". Effect shares the same syntax as its host meta language (TypeScript). Effect being valid TypeScript, it’s not a new language (as in GPL / General Purpose Language).
@AdamRackis @EffectTS_ My current mental model, which the maintainers might disagree with, is this:. Effect should be treated like a new language, like Elm or ReScript, that happens to use TypeScript syntax. This language has a ton of benefits. Strongly-typed errors. Built-in handling of complex.

That’s also true when building and scaling a company. - Fixing small problems every day compounds a lot. - Having everyone on board share this common objective is a huge force multiplier. *Everyone*, not just the boss.
@mattpocockuk It is impressive how much comes literally by compounding effects of small improvements, each individual one seems irrelevant but the sum generates a big change.

RT @c9antoine: Happy to announce that I’ll be giving a talk (3 talks scheduled) at the very first @EffectTS_ Paris meetup we are organising….

If you're using TypeScript in 2024, you should definitely have a look at Effect. It's stable and production ready. The leap is like going from callbacks to promises, and it's well worth it.
effect.website
Effect is a powerful TypeScript library designed to help developers easily create complex, synchronous, and asynchronous programs.
Effect is finally API Stable! . Starting with 3.0 the main package will follow semantic versioning: .→ major releases will include breaking changes .→ minor releases will include new features and new modules .→ patch releases will include bug fixes

Well @davefarley77 certainly is someone most software engineers should follow. I’m a Farleyist, if that’s a word.
Most software job interviews include a session where the applicant is quizzed on details of the programming language in use by the team. But does skill with your programming language really matter?.#Thread . 1/12.
