Aliases in Graphql.
Let’s say we have a query that return us the cars Data. If we add both the queries, we will get an error.
Fields "cars" conflict because they have differing arguments. Use different aliases on the fields to fetch both if this was intentional.
UseCase Example:
👇This will throw error


{  
  cars(filter: "name = Cars") {
    edges {
      node {
        name
        speed        
      }
    }
  }
  cars {
    edges{
      node{
        name
      }
    }
  }
}


👇This will work


{  
  slowCars: cars(filter: "Cars") {
    edges {
      node {
        name        
      }
    }
  }
  fastCars: cars {
    edges{
      node{
        name
      }
    }
  }
}


It works because we are using aliases here. Aliases let us change the names of the data that is displayed in a query’s results. It is incredibly helpful when we need to fetch the same data using different filters.

We have 7 different TypeScript utility types, like Pick Omit Partial NonNullable React.ComponentProps React.MouseEventHandler and special one React.PropsWithChildren

React's utility type PropsWithChildren enables components to take both props and child elements as input.

It is used in the definition of the component to identify the types of properties it can receive, including the children prop, which contains any elements contained within the component's JSX. In addition to children, it allows for the use of various props.

UseCase Example



const Track = ({ children }:PropsWithChildren) => {
  return (
    
{children}
); };

When using dynamic classnames, further conditions can be added depending on whether the initial condition is true or false.

Example:


{icons &&
   icons.map((icon: any, index: number) => {
      return (
         
{icon.icon} {icon.name}
); })}


If the expression index % 2 (modulus) evaluates to true, the class name col-span-4 will be added. The second className which is col-span-3 and it is added if the expression !(index % 2) evaluates to true. However the ! mark changes the Boolean to false

So class col-span-4 is added when the index is even, whereas the class col-span-3 is added when the index is odd.

Using Material UI to create an interface, use the icons, buttons, layouts, navigation and other MUI components. Using the sx prop to add css to individual components without using styled or tailwind classes.
install MUI:


npm install @mui/material @emotion/react @emotion/styled 


import the suitable components:


import { Box, IconButton, Paper, Typography } from "@mui/material";


simply use them like normal tags and add inline styles using the sx prop. The sx prop allows us to use a superset of css classes making it very intuitive to use.

React.Children

We can use the React.Children APIs to modify elements created by React before they’re rendered. It provides utilities for dealing with the this.props.children opaque data structure.

For example :-



React.Children.count(children)


Returns the total number of components in children, equal to the number of times that a callback passed to map or forEach would be invoked
