Custom Pipe - Angular (Tutorial #16)

In this video we will learn about Custom Pipe in Angular.
Pipes are one of the interesting feature of angular but sometimes built-in pipes are not sufficient for our formatting data , there we create Custom pipes
Use this link to share this video: • Custom Pipe - Angular ...
To create custom pipe we need to create a .ts file and that file will be a pipe with the help of @Pipe decorator. Use ng generate command to create Custom pipe
ng g p pipes/age
here it will create one pipes folder inside app folder and inside pipes folder it will create age.pipes.ts
All Custom pipe must implements PipeTransform interface and we need to define transform() method. Transform method will define the logic for custom pipe. Transform() method takes atleast one parameter that is used to hold the data on which we are using pipe. and if your pipe is parameterised then we need store that value after the first arguements
transform(value: any): any {
let currentYear:any = new Date().getFullYear(); // 2018
let userBirthYear:any = new Date(value).getFullYear();
let userAge = currentYear-userBirthYear;
return userAge;
}
We are taking date of birth from template and from this date we are extracting only year to get the age of the user.

Don't we have to import that pipe in our component.ts ??

[@dikshantyadav1110]

why did u use LET? cant we declare the variable's without let? in pipe's?

[@NishaSingla]

We use but in recent version of javascript(ES6) we use let and const to declare variable.

[@AayushiGupta251293]

By the person gets on pipe he must be having much knowledge about angular by then. And the content of the video is much more thats get boring to watch and mix up with thing we are looking for. Please keep it short and simple... Like by no u dont have to say how to generate pipe from cmd. And also u dont have to say why the column was null it was obvious as return was clearly null

[@NishaSingla]

Thanks for your comment but I don't think it is not relevant according to this topic. Every learner is not that quick like you, so content is designed according to any type of user so that they can easily pick the content doesn't matter they know about angular previous stuff or not and there is nothing wrong to explain small things in between because I have seen so many learners faced this issue. So relax and keep learning :) Have a good day

[@yugkrish3544]

Great video
