Thanks Thiago. We have 1 project with: 9 files depending on t5/core/ajax 2 files depending on t5/core/console 8 files depending on t5/core/dom 21 files depending on t5/core/events 16 files depending on t5/core/zone
Another project with: 1 file depending on t5/core/dom 1 file depending on t5/core/events 2 files depending on t5/core/zone We should be fine to manually update these files too.

[You don't often get email from dongmei....@icann.org.

TL;DR: do your Tapestry projects have JavaScript code that uses Tapestry's own JS like t5/core/dom, t5/core/zone, t5/core/ajax, etc? How many JS files have at least one of these dependencies? No exact numbers needed. We're just trying to figure out the size of possible backward compatibility problems. We've been working on improving the Tapestry's JavaScript support, including support for ES6 modules[1], creating a non-Require.js mode (based on ES6 modules) and converting Tapestry's own JavaScript sources from CoffeeScript to TypeScript. The last part should help everyone developing Tapestry's JavaScript, since CoffeeScript's syntax is way closer to Ruby than to JavaScript itself. In addition, CoffeeScript is old and its last commit was more than 2.5 years ago [2], while TypeScript is being actively developed and gaining adoption. There's one problem with TS's code generation, though: while it can output both ES6 modules or AMD ones (the ones used by Require.js), the AMD modules' exports are done in a bit different way. For example, if you have this: define(["t5/core/dom", "t5/core/ajax"]], function(dom) { var foo = dom("bar"); ajax(...); ); you'd need to change your code to define(["t5/core/dom"], function(dom) { // The __importDefault function is generated by the Ts // compiler and fixes the problem dom = __importDefault(dom); ajax = __importDefault(ajax); var foo = dom("bar"); ajax(...); ); or define(["t5/core/dom", "t5/core/ajax"], function(dom) { var foo = dom.default("bar"); // Notice the '.default' part ajax.default(...); ); Notice the changes would only need to be done once, when upgrading to 5.10.0, and they're simple. This problem only happens for Require.js/AMD modules. If, after upgrading to 5.10.0, your ES6 modules will import the ones provided by Tapestry normally. There are tools for converting AMD modules to ES6 like https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2F%2Fgithub.com%2Fbuxlabs%2Famd-to-es6__%3B!!PtGJab4!4RVteosWX-_pSZ_xgfUICvIViRyaXfx3KoMtkZRJLzxbUhyjoB0BQ7eQVopkTZqET1sEncDBzpsmQ2q477IWPn8p%24&data=05%7C02%7CNiran.Abeygunawardena%40clarivate.com%7C026d13f362124913231108dda9a25c3a%7C127fa96e00b4429e95f972c2828437a4%7C0%7C0%7C638853236980076965%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=k78F3H1aEP0THbOzjPlw%2Bk4W3rFkvHUajpnpNat%2FIGU%3D&reserved=0<https://urldefense.com/v3/__https://github.com/buxlabs/amd-to-es6__;!!PtGJab4!4RVteosWX-_pSZ_xgfUICvIViRyaXfx3KoMtkZRJLzxbUhyjoB0BQ7eQVopkTZqET1sEncDBzpsmQ2q477IWPn8p$> <https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2F%2Fgithub.com%2Fbuxlabs%2Famd-to-es6__%3B!!PtGJab4!4RVteosWX-_pSZ_xgfUICvIViRyaXfx3KoMtkZRJLzxbUhyjoB0BQ7eQVopkTZqET1sEncDBzpsmQ2q477IWPn8p%24&data=05%7C02%7CNiran.Abeygunawardena%40clarivate.com%7C026d13f362124913231108dda9a25c3a%7C127fa96e00b4429e95f972c2828437a4%7C0%7C0%7C638853236980097898%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=h5u4JivkfFN4EYG9yrmB0iJIYzhehH6K03L506CDtSo%3D&reserved=0<https://urldefense.com/v3/__https://github.com/buxlabs/amd-to-es6__;!!PtGJab4!4RVteosWX-_pSZ_xgfUICvIViRyaXfx3KoMtkZRJLzxbUhyjoB0BQ7eQVopkTZqET1sEncDBzpsmQ2q477IWPn8p$>> [github[.]com]. If you have a small number of files, doing it manually only takes a few minutes each at most (my own experience while converting Tapestry's AMD modules to ES6) and your code will look better and more modern in the end. We, the Tapestry team, would like to know whether this would be a problem for your projects, especially if it would prevent upgrading from 5.7.0+ to 5.10.0. With your feedback, we'll be able to define how to best use our time, either trying to configure some source code transformation tool to change TypeScript's output to avoid the problem above [3], creating a migration tool or just investing in other Tapestry parts if this backward incompatibility isn't a big deal for your projects.
