Today I worked on facade. Now there's a design pattern called facade it allows us to write a lot more readable and cleaner code. So there's one main class and basically it talks to other subclasses and handles all the logic itself now a client should work only with that main clas

Today I worked on integrating the qwep platform. Now the qwep platform allows us to use their crosses for car details say if a user didn't find a certain part they can use a cross or alternative instead. Now we need an article of a car part with that we can get a list of brands

[Tim WD @Timirlan94]

Today I worked on web sockets connections and disconnections. Now that problem I faced a few days ago was about improperly established closing states when work was done or users left or closed the page. Now the backend handled closing fine but front didn't send a close signal

Today I worked on sorting offers. Now I need to sort a list of offers coming from the zzap platform, now if it's a local offer it should on top of ranking on the page. Now I used a generator to go through all offers one by one and not to load all offers in memory. Then zipped it

[Tim WD @Timirlan94]

Today I worked on web sockets. Now I needed to create a new page and render user's search results onto that page using web sockets and Django channels. Now I established the web socket instance using js on front and Django consumers and routings on the server side. Checks out 👍

[Tim WD @Timirlan94]

Today I worked on mosquito. Now I needed to first get the data that a user puts into a search bar then send it upto mqtt broker and now other services that subscribed can get that data save or massage it and send that modified data back to mqtt so now interested services use data

[Tim WD @Timirlan94]

Today I worked on the mosquito message broker. Now today I was learning and studying about Mosquito Broker or mqtt. Now Mosquito is software that allows a multiple services to talk to each other so it acts sorta like a postoffice when people send messages through centralized area

[Tim WD @Timirlan94]

[Tim WD @Timirlan94]

Today I worked on saving data. Now I needed to get data from zzap and save it with no duplication, added unique=True to fields needed to be unrepeatable, added 'unique_together' to models for the same reason, connected zzap models with core models through ids, no straight connect

[Tim WD @Timirlan94]

Today I worked on sending article data and product data to the core app. Now I needed to send data to the core through the redis service, now once I get data from zzap I save it to redis temporary then I call a webhook on the core, trigger that redis data and save it to core db

[Tim WD @Timirlan94]

Today I worked on receiving data from the zzap platform. Now I needed to get the data based on a part number, region and name of a car part, received that data, now I need to put that data upto redis and then synchronize it with the core project. Have location, name, shop name..
