@tony.kay I am using pathom/new-parser to create a parser, does it add the env plugin by default or do I need to add it explicitly ?

murtaza5204:05:25

(pathom/new-parser config 
    [(attr/pathom-plugin all-attributes)
     (form/pathom-plugin save/middleware delete/middleware)
     (datomic/pathom-plugin (fn [env] {:production (:main datomic-connections)}))
     (blob/pathom-plugin bs/temporary-blob-store {:files         bs/file-blob-store
                                                  :avatar-images bs/image-blob-store})]
    [automatic-resolvers
     form/resolvers
     index-explorer
     (blob/resolvers all-attributes)
     ...])

I assume you are referring to com.wsscode.pathom.core/env-plugin or com.wsscode.pathom.core/env-wrap-plugin, however to use both of these I will have to provide static values. I need something where I can access the :pathom/context in each invocation of the parser.

tony.kay05:05:15

If you’re looking to see something throughout the call of all resolvers, then adding to env is the approach. If it is something that came from the client but was targeted at a single resolver (i.e. parameters on a query prop) then copying it over to the env map at the plugin layer will ensure you see it everywhere.

murtaza5205:05:05

can you point me to an example on how to copy it at the plugin layer. Bcoz as I understand I dont have access to the params at the plugin layer.

The pathom context is in the existing env, likely under the :ast key. Just print it out and explore

I saw this on twitter, and it is a worthwhile read: https://macwright.org/2020/05/10/spa-fatigue.html I think this is a great reminder that not every problem is a nail to be hit with your hammer. 🙂

I’ve been seeing things like this being mentioned as “another” way, https://unpoly.com/

levitanong13:05:23

I’ve read this a couple of days ago, and while he does have a point, I think he’s missing a crucial benefit of react-like models: ease of reasoning.

folcon13:05:25

To be honest I'm not certain that there isn't a way to maintain ease of reasoning while still using the above the approach? But there's a definite benefit in that we already know how to do that with the react-like models.

tony.kay17:05:29

Oh, I’m not implying that I think SPA’s are fundamentally flawed somehow. I think that’s where things should go. That said, React isn’t the only way to do it, and the vanilla js-land way of doing it has gotten really twisted in certain ways. Personally I agree with the whole server-side rendering complaint. I’ve never personally found it at all sane to do that. If Om Next didn’t have the code for it already, it wouldn’t be in Fulcro. But I am glad to have isomorphic operation. That turns out to be an interesting case where the ability to run things in the JVM does come in handy. Also, I agree that building your common business website as an SPA instead of just using a website builder is usually a mild form of insanity. But, if what you’re building is a thing that should behave more like a desktop application for the web, then an SPA makes a lot of sense. What I liked about the article was that it is challenging us to think about what we use our tools for…I’ve seen it over and over again that people will choose a tool “because the know it” or “because it looks cool” and not really think through the long-term implications.

Does RAD generate mutations for crud for the different entities, I am looking for simple crud mutations, given an :id, the entity is deleted, or a new entity is created etc

murtaza5214:05:18

How do I trigger a generated mutation from the parser. I have included the save-middlewarewhich in turn uses the (datomic/wrap-datomic-save). This uses the ::form/paramsto save any deltas in datomic. How do I call it from the repl -

(parser {::form/params
           {::form/delta {:farm/id #uuid "5eb40c62-164d-481a-bb53-463e1e3d8ad2"
                          :farm/name "New Farm"}}}
         [])

The above does not yield any result.

Jakub Holý (HolyJak)17:05:34

There must be an example in the RAD demo?

murtaza5220:05:14

going through the rad demo codebase, lets see what I can find
