Suggestion for code flow/visual representation

Any tool or software for nodes js/typescript etc.,
Is there is any VS Code plugin to visualize Node JS, Typescript, Code with easy mapping like mind maps, reverse engineer to DB...Putting
debugging check the manual flow is harder and not redeable...else Any Visual representation of breakpoint kind of a tree structure to
easily understand the entire flow of execution

Basically want to understand the code flow quickly  
my question is why inner join behaves differently. is it a bug or code smell or how DB works?
I come across this https://sqlnuggets.com/performance-problem-when-using-or-in-a-join/ but couldn't understand why OR is creating performance issues

Please kindly explain in detail

Hi,

I'm facing GraphQL (N+1) query problem and it is been clearly explained in the video https://www.youtube.com/watch?v=ld2_AS4l19g&ab_channel=knowthen on how we can solve the problem.

However not sure on the following, Please help me with source code if possible, Thank you so much in advance.

Books returns 4 and query executed 4 times
User returns 8 and query executed 8 times
Department returns 4 and query executed 4 times

only one difference at the end of the schema it is defined as BooksPaged! similarly for others as well

In my Case
a. Books
b. Users
c. Department

query {
 books{
 total  
  users {
    total
    department{
        name
     }
 }
  }
}

Thanks
Can someone help me with list of AI tools or websites used for programming, debugging, checking sql optimization or development ???
Hi,

There are more than 15 joins made to display the dashboard page in mysql and slows down as several read/write done on the tables frequently.

Solution:
1. Move the complete DB to in-memory cache like redis. Sync redis with DB. Query redis instead of DB
2. Restructure the tables or paritition the tables in to further many tables
3. Identify the exact root cause --> but EXPLAIN doesn't help much

Please advise

Thanks
Tim,

i couldn't find one note taking app which does the following?

a. create notebook collections
b. share as public URLs with search
c. create read-only credentials and provide the credentials for the users to access or use the same credentias

Is it possible for you to give a try to build this project with latest python and help me?

Thanks
