T-Hub, Hyderabad

##About the event

After successful editions in Bangalore and Pune, ReactFoo travels to Hyderabad. The Hyderabad edition will focus on the following topics:

Success and failure stories of implementing React and React Native for your use-case.
Your experiences with alternatives to React – such as Angular, Vue and other frameworks – why these worked / did not work for your use-case.
Front-end architecture patterns and approaches with React.
Mobile engineering with ReactNative or alternatives.

ReactFoo Hyderabad is an event for JavaScript and front-end engineers. All speakers must have direct experience working with React, ReactNative or alternatives to these.

Format

We invite developers and architects from large and small organizations to share their stories and insights with the community. You can either propose:

Full length talks of 40 mins duration.
Short talks of 20 mins duration.
Birds Of Feather (BOF) sessions.
Hands-on workshops for 3-6 hour duration.

Workshops on 18 March will be announced shortly. 30-40 participants will be admitted to each workshop. Workshop tickets have to be purchased separately.

Who should attend

JS engineers from enterprises.
JS engineers from startups.
Architects.
Cross-platform mobile developers.

Why you should attend?

To learn from and network with peers from the industry.
To gain insights from case studies of practical implementation, and evaluate ReactJS and React Native for your work.
To program better with React and React Native.

Talk selection process

Speakers from previous editions will review proposals and vote on them. In order to make it to the shortlist, your submission must contain the following information:

Key insights you will present, or takeaways for the audience.
Overall flow of the content.

You must submit links to videos of talks you have delivered in the past, or record and upload a two-min self-recorded video explaining what your talk is about, and why is it relevant for this event.

Also consider submitting links to the following along with your proposal:

A detailed outline, or
Mindmap, explaining the structure of the talk, or
Draft slides.

Honorarium for selected speakers; travel grants

Selected speakers and workshop instructors will receive an honorarium of Rs. 3,000 each, at the end of their talk. Confirmed speakers and instructors also get a pass to the conference. We do not provide free passes for speakers’ colleagues and spouses.

Owing to a tight budget, we will not be able to offer travel grants or accommodation for this event.

Important dates

ReactFoo Hyderabad conference – 17 March 2018.
ReactFoo Hyderabad hands-on workshops – 18 March 2018
Last date for submissions - 15 February 2018.

Presto: Building cross platform transactional apps using FP. Works with React

Submitted Feb 15, 2018

Section: Full talk Technical level: Beginner

Transactional apps are nothing but simple conversational flows between the User and System. They can be written using a simple UX DSL leveraging continuation passing style (CSP) semantics. Despite this being the most important problem to simplify, we find that the current frameworks complicate the building and maintenance of transactional apps, requiring heavy investment in engineering effort and the development process is not a pleasant creative experience.

At Juspay, we saw no reason for this to be the case, and set out to create a framework to dramatically lower the barriers of entry for quickly building out solutions to typical real world applications. Being strong believers in the functional programming paradigm, we abstracted out all the parts of an app as extremely composable lego blocks / pure functions.

As a JavaScript house, we explored a number of options and chose PureScript as our core
language. Purescript has the conciseness of Haskell paired with the ubiquity of the JavaScript interpreter. The UI components and business flows are simple pure functions that are reusable across apps. The frontend and backend are unified, represented as a continuation of flow between the client and server.

In the last several months, we have made major strides towards allowing everyone in our company to be able to examine and write the code of the apps we are building -- from fresher to product manager to designer. We have trained around 100 interns on Haskell and PureScript to work on our platform in production. We have been able to deploy this framework into production in serious payment and banking systems.

In this talk, we will share our experience building apps using Presto, a FP based DSL. We will also see how Presto can be used with React.
