ReactFoo 2019

A gathering of over 250 web and mobile developers working with React

About ReactFoo Bangalore:

ReactFoo Bangalore comes back to its original home after completing five successful editions, India-wide:

  1. ReactFoo Bangalore - September 2017
  2. ReactFoo Pune - January 2018
  3. ReactFoo Hyderabad - March 2018
  4. ReactFoo Mumbai - May 2018
  5. ReactFoo Delhi - August 2018

ReactFoo Bangalore will bring together over 250 developers working with React, and who are invested in building a space for conversations around experiences using React in production.
ReactFoo Bangalore is a single-day, single track conference with talks, office hours and Birds of Feather(BoF) sessions. Workshops will be held on 1 and 3 March, before and after the conference.

Who should attend ReactFoo:

  1. Front-end engineers
  2. Teams and companies who are evaluating frameworks to use for running applications in production
  3. Cross platform mobile developers

ReactFoo provides you the opportunity to:

  1. Learn from and network with peers from the industry
  2. Gain insights from case studies of practical implementation, and evaluate ReactJS and React Native for your work
  3. Understand how to run React in production, end-to-end, rather than only build an application with React

Hosted by

A community - for and of - front-end engineers to share experiences with ReactJS, performant apps with React, crafting better User Interfaces (UI) with React and GraphQL ecosystem. ReactFoo also discusses design patterns and user experience. more

Re-rethinking best practices with React, ft react-suspense

Submitted Jul 19, 2018

In recent times we are seeing a big shift in the way we do front end thanks to React community i.e. MVC is not the norm, we don’t write CSS in CSS, we don’t write HTML in HTML, we don’t necessarily do templating and now we are going to start throwing promises (not actual promise but you know JS promises). I am going to talk about why certain pre conceived notions of best practices can be broken by setting some simple constrains on the mental model/systems and breaking those notions can actually result in some cool breakthroughs and features.


I will be going through different established best practices and constrast it with how React approached it to show why its sometimes okay to break it, if it results in some awesome possibilites.

For example, MVC was the norm and most frameworks tried to adapt to the pattern which resulted in too much context switching while managing controllers/models/templates and keeping them in sync resulting in loss of productivity, increase in complexity and just by taking a component approach where all of that is encapsulated using pure functions and immutable state we are better able to reason/compose our UI and considerably more productive.

Finally I would like to talk about react-suspense. A new feature thats going to get introduced where they have used something like try/catch as means to control side effects which is unheard of and in doing it they have made the render function a “impure” function yet it results in clean abstraction. Again they took a really unconventional way which resulted in good abstraction and some cool possibilites.

Speaker bio

I am a consultant with Equal Experts and have been building UIs for a couple of years now.

When I started doing front end programming I learned bunch of stuff from various sources to be best practices and coded as such, in doing so I could see the problems with it but since all the sources I had told me that it was best practice I assumed there must be some wisdom in it that I didn’t see, so continued to code as such. Only after React came along I felt like finally somebody agreeing with me :-).

Of course that doesn’t mean that all best practices are bad practices just that sometimes we stop questioning things just because its the norm which stopped me personally from exploring new stuff, so I want to share that wisdom and the insights I got along the way.

My React (Native) app speaks GraphQL

At BAM, we started using GraphQL alongside Apollo Client on a large internal app for a French car manufacturer. Along the way, we laughed and we cried … we hit some rocks, we fell down, we stood back up, we faced many questions. Frontend architecture and responsibility distribution, cache updating, error handling… After one year, we came up with best practices for these challenges, and we eventua… more
