Because it provides a ton of the mechanisms for what you ask below, works well, handles a ton of periphrenalia that I really do not want to deal with directly. The good bit is that the frontend piece (the actual PWA) can be written in any way you want provided that at the end there is some JS code handling the UI. Services can be provided as cloud functions of Google Cloud and nothing prevents them from being in Pharo. In the Firebase SDK, there is a command line tool that provides for local execution of the generated JS and one can then push that code to the server side. Integration with Google general push notification system is easy to implement as well. Costs of operation are quite low, even for pushing to large user bases. There is of course the "database" component (the actual "Firebase") that is key/value pair system, along with read/write policies (which can be quite complexand support quite a number of situations very well, provided the schema is well done) and if what one needs is a relational DB, this is not really the same thing. So, that's how I would do PWAs, they work nicely using that very stack.

[ANN] PetitParser2 for VisualWorks (Was: [vwnc] Parsing in Smalltalk)

by Steffen MÃ¤rcker

Hi, I am happy to announce that I've just finished an initial port of (the impressive) PetitParser2 (https://github.com/kursjan/petitparser2) to VisualWorks. It is available in the Public Store. The port consists of 4 bundles: * PetitParser2 * PetitParser2-Tests * PetitParser2-Smalltalk (defunct, test support only) * PetitParser2-Validation (defunct, test support only) I'd be happy to hear your comments. Cheers, Steffen

To be able to send push notifications from a Pharo server I will also need an implementation of the Web Push Protocol [3] and the VAPID spec [4]. Do you know any previous related work in Pharo or should I think in my own implementation? The two protocols you mention are based on HTTP/2, which we do not (yet) have. We do have WebSockets in Zinc, which might help in understanding the issues at hand. Sven

Have you also looked at Willow - https://link.medium.com/Iyj4qo2BfR? It has spa âs in mind - although Iâm not sure of the proâs/cons vs Pharo js which also looks good too. Would be interested in what you decide.

Re: [Pharo-users] ring deprecation in pharo 7

Hi, the Ring 2 is not integrated because we do not want to have two version in the system at once and we are not ready for the old Ring removal. However, it is marked as deprecated to warn people that they probably should not base their new code on it. That is important for more intensive usage of the models. Most people want to simply have something like a method reference. In that case, you can still use the old Ring. We will add some class comments to clarify that.
