NodeJs - 在所有页面上共享类别列表

Question

I am building a website where the navigation bar contains a drop down list which contains the following categories:

1. Web Development
2. Mobile Development
3. Desktop Development
4. Programming

Do i need to retrieve the above categories every time a new page of my application is requested. For example:

• For the home page i retrieve the categories from the database.
• For add product page i also retrieve the categories from the database.

I know that my approach is not efficient, Is there a better way to accomplish it.

Kindly note that i am using pug template engine

Thanks

Answer 1

the better way to get what you want is using Redux, it lets you share variables above all the code. it's simply to implement.

you can see the documentation here
