Swift Lambda VSCode extension

We've got two guests Steven Van Impe & Marwane Koutar (AWS internship @sebsto was the mentor).
They created a VSCode extension to facilitate the development of a Swift Lambda function.

Live demo

templates to initialize a project, such as API to Lambda
utilizes a Makefile to bundle a zip file & the binary
local invoke feature: test the Lambda functions locally
automatic deployment from the VSCode extension
remote invoke: call the deployed lambda function remotely

Swift Lambda VSCode extension

Extension is publicly available: just search for - Swift Lambda.

Source is under swift-on-server-community @ GitHub
Custom template support, everyone can create templates
Early sneak peak, feedbacks are appreciated

2024 goals

Concurrency & Structured Concurrency adoptions

Guide for structured concurrency @FranzBusch @Joannis_Orlandos
- Ongoing work, some guides are in progress @FranzBusch
- @Joannis_Orlandos covered structured concurrency well on swiftonserver.com (link1, link2)
- We're good on this front, community is also helping. Our main focus shouldn't be concurrency. @FranzBusch
Overview of where we are standing with our libraries and the remaining work @FranzBusch
- Consensus reached on hiking ecosystem toolchain requirements to 5.8

Swift 6

Compatibility testing the packages @finestructure
- We've run four passes of Swift 6 toolchains across all packages and collected error stats
  - SSWG Swift 6 Testing
- Swift 6 status page just went live with the summary & overview @finestructure
  - Ready for Swift 6?
- Still need to drill down into SSWG packages @finestructure can provide the results
  - Everything in the Apple org + SSWG report would be nice @FranzBusch
NIO needs to finalize its Sendable annotations @FranzBusch
- Work is already scheduled, but not started just yet @FranzBusch
- @tiborbodecs send streaming related GitHub issue (HB2) link to @FranzBusch

Marketing

Important to address ongoing discussions on forums, clarify misleading benchmarks @ktoso
Think about two guides that either need to be overhauled or created from scratch
Build out integrated example project @FranzBusch @tiborbodecs
User group meetings @Joannis_Orlandos & @sebsto
- Swift Server Side Meetup #02
Show-case two server side projects/success stories @0xTim @ktoso
swiftonserver.com @tiborbodecs @Joannis_Orlandos @taylorswift
- Integrated with swiftinit.org, including tooltip support
- Open to article contributions
- Can leverage our subscriber list

Tooling

Apple interested in taking over Swiftly project - WIP @FranzBusch

HTTP server and middlewares

Hummingbird is progressing well @Joannis_Orlandos @adam-fowler @FranzBusch @tachyonics @tiborbodecs

Benchmarks

Get NIO benchmark results & share it with the compiler team @adam-fowler @tachyonics @Joannis_Orlandos @FranzBusch

Agenda

Josh Elkins

@jbelkins

Re-introduction to the workgroup members
Upcoming product launch around September
Can't commit time to SSWG until the end of the summer

@FranzBusch

It is valuable to provide feedbacks and keep attending the meetings

Swift version support

@FranzBusch

Swift projects support the last 3 versions or the versions from when they were released

Benchmarks

@ktoso

Recent forum thread about Swift benchmarks - link1, link2

@ktoso

Idea:
- Baseline benchmark, that we run somewhere or give instructions how to run it
- Share the results with the compiler team + optimize based on the results
- For example an http workload or something similar

@FranzBusch

NIO HTTP server benchmark instead of Vapor benchmarks
NIO optimization with ownership modifiers for example
Framework level benchmarking brings in too much complexity

@ktoso

Benchmarking goals:
1. Make compiler folks to work on the issues
2. Actually improve the numbers

@FranzBusch

Propose to roll benchmarking into the SSWG goal this year.

@tachyonics

Do we want to benchmark AWS Lambdas?

@sebsto

Already benchmarking HB & Vapor inside Lambdas, common use-case, but no exact method

Showcase

@Tim

Showcase - link

@sebsto

Maybe a good candidate for an upcoming meetup around September?

@ktoso

I have a contact there, I can ask about this.

swift.org - SSWG related pages

Work in progress @tiborbodecs @Joannis_Orlandos
Public fork available here.
Add OpenAPI related tutorials to the top level page ask @Honza_Dvorsky about this.

@ktoso

Add distributed actors guide, contact @Joannis_Orlandos + @tiborbodecs

@tachyonics

Why choose vapor or hummingbird? (pros / cons)

@0xTim

Listing companies is going to be problematic, listing other tutorial sites should be fine.

@tiborbodecs

Will continue to work on the website together with @Joannis_Orlandos
