If you were going to build a website with Web Components, what tools would you use?

We’re working on a new static rendering tool for CanJS 6!

Got an old CanJS app? We've been working on making CanJS 2.3 work directly with CanJS 5 and 6: github.com/canjs/can-23

Exception breaking your canjs app? Add window.onerror = function(){ can.queues.flush(); } This reruns the queues.

@matthewcp Thank you for the article. I'm writing @inertiajs adapter for @canjs I hope I'll get a working version by the weekend.

@Guido_Smeets If you need any help upgrading, let us know! @bitovi has a lot of experience upgrading projects. Currently working on a 4.x -> 6.x project right now. 😃

@canjs Awesome, I thought that the new observables didn't work in IE11. Our upgrade will probably be divvied into two goes, first 2.3 -> 3.x, then 3.x -> 6.x later

@canjs up till which version do you support IE (10/11)? I'm investigating an upgrade path to 6.x from 2.3, but still need to support IE for a little while..

@Guido_Smeets To be clear: the new observables (can-observable-array & can-observable-object) don’t work in IE11, but “legacy” observables (can-define/can-map/etc.) do work in IE11 in 6.x

@Guido_Smeets 😬 If you need this fixed in 2.3, PRs branched from github.com/canjs/canjs/tr… are welcome 😃

@canjs In fairness, it's a bug in canjs, because that specific file misses an explicit dependency on some other file, but it's strange how this stuff can work for years without issue and suddenly magically break.

Chrome is so interesting. Now, after 3 years my unit test project suddenly fails during loading @canjs 2.3, because of some requirejs dependency loading issue. Only in Chrome, half the time. Fx works fine. Gotta love them breaking micro-optimisations.

CanJS 6.0 has built in support for strict type checking ✅ and APIs for “maybe types” and handling type conversion. This new type system will help you catch errors before your users ever see them:

If there are any @CanJS developers in the Netherlands looking for a job, send me a DM, we're hiring. You can work on probably one of the biggest CanJS projects in Europe. :)

Heh, our @CanJS based flagship SPA has reached 400 functional components (basically, 400 unique pages). What a milestone.
