JSFoo 2017

JSFoo is a conference about JavaScript and everything related.

About the conference: JSFoo is a JavaScript conference hosted by HasGeek.

Theme this year: The broad theme this year is going to be Building Reliable Web Apps. Please refer to the Topics section below for the subject of talks and workshops we are looking for.

Format

We are inviting proposals for:
Full-length 40 minute talks.
Crisp 15 minute talks.
Sponsored sessions, of 15 minutes and 40 minutes duration (limited slots available; subject to editorial scrutiny and approval).
Hands-on Workshop sessions, 3 and 6 hour duration.

Selection process

Proposals will be filtered and shortlisted by an Editorial Panel. Please make sure to add links to videos / slide decks when submitting proposals. This will help us understand your speaking experience and delivery style. Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled will help the Editorial Panel better judge your proposals. We might contact you to ask if you’d like to repost your content on the official conference blog.

We expect you to submit an outline of your proposed talk – either in the form of a mind map or a text document or draft slides within two weeks of submitting your proposal.

Selection Process Flowchart

You can check back on this page for the status of your proposal. We will notify you if we either move your proposal to the next round or if we reject it. Selected speakers must participate in one or two rounds of rehearsals before the conference. This is mandatory and helps you to prepare well for the conference.

A speaker is NOT confirmed a slot unless we explicitly mention so in an email or over any other medium of communication.

There is only one speaker per session. Entry is free for selected speakers. As our budget is limited, we prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. HasGeek provides these limited grants where applicable: two international travel and accommodation grants, three domestic travel and accommodation grants. Grants are limited and made available to speakers delivering full sessions (40 minutes or longer). Speaker travel grants will be given in order of preference to students, women, persons of non-binary genders, and individuals for Asia and Africa first.

Topics

Updated (19 April 2017): We are currently looking for talks in the following topics:

Testing: Testing tools and strategies; test driven development and testing culture; continuous integration and testing workflows; and case studies around testing your application.

Performance optimization: Performance analysis tools and techniques; best practices for building performant applications; browser, NodeJS, and framework internals; network protocols; and performance case studies.

Debugging: Tools for locating and fixing bugs in JavaScript applications; real world post-mortems of bugs that affected your organization; and using telemetry for debugging.

Immutability, type checking, and alternative programming languages: Alternatives to vanilla JavaScript; functional programming and immutability; types and type systems; and real-world case studies of introducing alternative programming languages and tools in your organization.

Build tooling: Build tools and automation, including task runners, linters, JavaScript bundlers, CSS pre- and post-processors, continuous integration tools, static analysis tools, and optimization tools.

Crash and performance monitoring: Monitoring applications for crashes and performance issues while in production.

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like for it to be available under a permissive open source licence. If your software is commercially licensed or available under a combination of commercial and restrictive open source licences (such as the various forms of the GPL), please consider picking up a sponsorship. We recognise that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a “sponsored session”.

Important dates

Deadline for submitting proposals: 15 June 2017

Conference dates: 15–16 September 2017

TypeScript all the things!

Submitted Feb 8, 2017

You’re probably doing something wrong if you write JavaScript for a living in 2017 and haven’t yet tried TypeScript. Whether you’re writing a back-end, front-end or a mobile app — and whether you’re using jQuery, React, Angular, Vue or your favourite framework-du-jour — TypeScript can significantly improve your development experience with its incredible tooling and refactoring support that can help you catch bugs as you type and bring sanity to managing large codebases.

In this session, I’ll take you through the amazing world of TypeScript’s language features and its rich out-of-the-box IDE affordances such as cross-referencing and auto-completion, experiences that developers working with traditional statically-typed languages take for granted. I’ll also show you how all the latest ES2015/16/17 features are natively available in TypeScript with a greatly simplified configuration compared to Babel’s and how you can take advantage of static typing to auto-generate a nice documentation for your project.

Outline

I’ll probably take the following route:

  • Give examples of how unintended bugs creep into our JS code.
  • Introduce the concept of ‘thinking like a compiler’ to show how most of these common mistakes arise due to misunderstanding or incomplete understanding of how the language works.
  • Introduce TypeScript and show how it can point out these bugs to us right inside the editor, leading on to the motivation for static-typing.
  • Show how easy it is to set up a TypeScript project, with some often-used settings and config.
  • Show how to incrementally upgrade existing projects to TypeScript.
  • Introduction to DefinitelyTyped (and how easy it is to submit a PR to add new definitions or fix existing ones).
  • Show more complete examples of static typing and editor support in some sample projects (Node and React).
  • Show more advanced features of TypeScript.
  • Demonstrate how you can use TS interfaces to follow SOLID design principles.
  • Also talk about some gotchas and workarounds when writing some parts of traditional JS that don’t easily map to TS.
  • What to expect in the TS roadmap and how it’s aligned to future ECMAScript versions.

Stretch goals:

  • Try to cover some key differences between Flow and TS.
  • Honourably mention Elm and PureScript.

Requirements

Prior experience with JavaScript, with a general awareness of new ECMAScript features.
