Join us as we kick off Developer Day with an overview of what’s new for developers who are building on, or are interested in learning about, the Atlassian platform. We’ll share what’s new and what you can expect from partnering with Atlassian and a massive community of developers.

The web community is a fast moving community and over the recent years, many great frameworks and tools have emerged. Technology changes made in the past are not always the right ones today. This applies to Trello’s web stack too. CoffeeScript and Backbone were great choices 7 years ago but there are better tools and frameworks available now, so the Trello team decided to update its stack. But, how does one tackle this and how do you make sure you continue to innovate product-wise while modernizing its web stack? This is what we will discuss in this session -- main drivers for modernizing, the reasoning for choosing for TypeScript, React and GraphQL and will discuss our strategy implementing it, including two failed attempts. When leaving this session you will have learned which tactics to apply when modernizing a web stack and warning signs to be aware off.

Are you planning to develop a new cloud app? Serverless might be the right fit for you! Serverless computing makes it possible to write small functions while platform providers like AWS take care of the deployment and scalability. However, this new concept comes with its own drawbacks when used in production, such as long startup times and scaling challenges. Hence, we will show you what it takes to run a cloud app using a serverless architecture based on AWS Lambda. We will go beyond the basics to cover best practices and explain why serverless might be a good fit for you. You'll learn which setup options you have for your development and deployment environments, how to develop solid serverless functions, and where limitations exist. Using these learnings, you'll come away with knowledge for developing and scaling your cloud app to serve a growing number of customers and their users with an event-driven, serverless computing platform.

Whether you're a small startup or a high growth company, if you build apps for the cloud, you handle data and the rules that apply to data can be overwhelming. The European Union led the charge last year with General Data Protection Regulation (GDPR), and other countries are quickly following suit. The trend toward stronger data privacy laws is truly global and the definition of "best practices" is quickly evolving. In this talk, Erika Fisher, Atlassian's Head of Privacy, will walk you through what this "new normal" in privacy laws means for the data you handle, how you develop in the cloud, and how you can comply while keeping time and resources focused on what you do best: building awesome apps for end-users.

Third-party apps can contribute to poor Jira product experiences, especially on high-demand, large scale instances, across cloud, server, and data center deployments. In this talk, we’ll share the results of research performed by our premier support team and raise awareness about performance and stability problems being experienced by some of our large customers. We will cover concrete examples of problems encountered and provide suggestions for what developers can do to improve their app stability and performance.

Did you know Atlassian Connect is the foundation for many types of cloud apps? It handles discovery, installation, authentication, and seamless integration into the UI of Atlassian products. An Atlassian Connect app could be an integration with an existing service, a new feature, or even a new product that runs within an Atlassian product. At the end of this talk from Ralph Whitbeck, you will understand what Atlassian Connect is, how to build a basic app, and where to go to learn more. Audience members should be familiar with HTTP concepts. We’ll look at examples in JavaScript/Node, but knowing or using Node is not a requirement.

GDPR is the largest change in data privacy legislation that we've seen in the past 20 years. Atlassian is responding to this change with significant improvements to the developer platform which includes the introduction of a new identity model to centralize control of user profile information and new privacy control settings for customers. In this talk, we'll cover these changes, including the impact on your customers and your app development.

Atlassian Connect uses JSON Web Tokens (JWT) for authentication between third-party apps and Atlassian products. Every Connect app will need to use them, and no one wants to use something they don't understand. In this talk, Leo Huang will provide a fundamental understanding of JWTs and how they are used in Atlassian Connect. Encryption can sound like a scary topic, but this talk aims to prove that it's not that complicated, even for a beginner.

Why write three separate apps for Cloud, Server, and Data Center products, when you can write just one that works across all of them? Learn how splitting your app into appropriate layers allows you to write your UI and business functionality just once, yet have it run across all product deployment environments. We’ll dive into real-world code examples, from how to use Atlaskit, to building and packaging an app across all three product deployment options using Bitbucket Pipelines. As a bonus, we’ll share what we got wrong the first time we tried sharing code between cloud and server.

We're gradually opening the floodgates to let people integrate their cloud services with Jira and Jira Service Desk using OAuth 2.0 Authorization Code Grant flow (also known as three-legged OAuth or 3LO). Eero Kaukonen is here to show how 3LO apps work and how they are different from all the other types of apps you might've built for Atlassian products before.

After the session, you should understand how 3LO works and why you might want to build a cloud app for Jira or Jira Service Desk with it.

Puppeteer is a powerful library that provides a high-level API with almost endless possibilities, allowing you to quickly build tools and scripts on top of the headless browser. You can create them once and reuse on both local development and continuous integration environments. Thanks to Puppeteer we can now automate many tedious tasks instead of performing them manually, from automating a check to see how much JavaScript code was used on the page, to measuring and reducing the size of assets for improving performance and page load time. Do you want to keep your application performance metrics at a high level? Tired of Selenium? Maybe you would like to write functional tests directly in JavaScript? In this talk, you'll learn how the Puppeteer library can help you achieve all of this and more, all in a single tool.

"Security is everyone’s responsibility" is a phrase we often hear in software development, but it's easier said than done. As the adoption of Atlassian cloud products grow, the security posture of cloud apps in the Atlassian Marketplace gets scrutinized even more than before. In this talk, we will discuss some of the previously seen security issues in Marketplace apps, security pitfalls you can avoid while developing apps, and general security best practices Atlassian Marketplace app developers should aim for. We will also give a sneak peek on some of the security programs we have been working on geared towards improving trust in the Marketplace.

The Jira issue functions as the core unit of work in the software industry, connecting work across tools and teams of all kinds. The Jira issue view was recently redesigned from the ground up. It's now easier to understand what's most important and how to take action that will move work forward.

It is also the most viewed page in Jira and one of the top places to add additional functionality and context. We have thoughtfully updated the extension points available to take advantage of the new design patterns and information architecture.

In this talk, Taylor Pechacek will give you a deep understanding of why we made these changes, where we are at today, how your app can extend the new issue view, and future improvements we have planned.
