JSJ 277: Dojo 2 with Dylan Schiemann and Kitson Kelly

JSJ 277: Dojo 2 with Dylan Schiemann and Kitson KellyThis episode of JavaScript Jabber features panelists Aimee Knight, Cory House, and Charles Max Wood. They talk with Dylan Schiemann and Kitson Kelly about Dojo 2.[00:02:03] Introduction to Dylan SchiemannDylan is the CEO at Sitepen and co-founder of the Dojo Toolkit.[00:02:22] Introduction to Kitson Kitson is the CTO at Sitepen and project lead for Dojo 2.[00:02:43] Elevator Pitch for DojoDojo 1 has been around forever. Started back in 2004 as a way to solve the challenge of "I want to build something cool in a browser." Promises and web components were inspired by or created by Dojo. It's been a huge influence on the web development community.Dojo 2 is a ground up re-write with ES 2015, TypeScript and modern API's. It's a modernized framework for Enterprise applications.[00:04:29] How is Dojo different from other frameworks?There's a spectrum: small libraries like React with an ecosystem and community of things you add to it to Angular which is closer to the MV* framework with bi-directional data binding. Vue lands somewhere in the middle. Dojo 2 is also somewhere in the middle as well. It's written in TypeScript and has embraced the TypeScript experience.[00:06:00] Did the Angular 2 move influence the Dojo 2 development and vice-versa?Dojo 2 had moved to TypeScript and 2 days later Angular announced that they were going to TypeScript. Angular also moved very quickly through their BETA phase, which caused some challenges for the Angular community.With Dojo 2, they didn't start the public discussion and BETA until they knew much better what was and wasn't going to change. They've also been talking about Dojo 2 for 6 or 7 years.The update was held up by adoption of ES6 and other technologies.Dojo 1 was also responsible for a lot of the low-level underpinning that Angular didn't have to innovate on. Dojo 2 was built around a mature understanding of how web applications are built now.People doing Enterprise need a little more help and assistance from their framework. Dojo provides a much more feature rich set of capabilities.Angular could have pushed much more of TypeScript's power through to the developer experience. Dojo much more fully adopts it.It's also easier if all of your packages have the same version number.Call out to Angular 4 vs Angular 2.[00:12:44] AMD ModulesWhy use AMD instead of ES6 modules?You can use both. Dojo 2 was involved in the creation of UMD. James Burke created UMD while working on Dojo.ES6 modules and module loading systems weren't entirely baked when Dojo 2 started to reach maturity, so they went with UMD. It's only been a few months since Safari implemented the ES6 module system. Firefox and friends are still playing catchup.The Dojo CLI build tool uses webpack, so it's mostly invisible at this point.So, at this point, should I be using UMD modules? or ES6? Is there an advantage to using AMD?With TypeScript you'd use ES6 modules, but UMD modules can be loaded on the fly.[00:16:00] Are you using Grunt?Internally, for tasks we use Grunt. But for users, we have a CLI tool that wraps around Webpack.For package builds and CI, Grunt is used.[00:18:30] What is the focus on Enterprise all about?There are a lot of different challenges and complexities to building Enterprise apps. Dojo was the first framework with internationalization, large data grids, SVG charts, etc. Dojo has spend a long time getting this right. Many other systems don't handle all the edge cases.Internationalization in Angular 2 or 4 seems unfinished.Most Dojo users are building for enterprises like banks and using the features that handle large amounts of data and handle those use cases better.[00:21:05] If most application frameworks have the features you listed, is there a set of problems it excels at?The Dojo team had a hard look at whether there was a need for their framework since many frameworks allow you to build great applications. Do we want to invest into something like...
