Angular module importing in TypeScript can greatly enhance the overall functionality

Currently, I am diligently following the Angular tutorial here. Simultaneously, I am also delving into modules here. Within the tutorial, the author suddenly introduces this intriguing import:

import { Component, OnInit } from '@angular/core';

My curiosity was piqued when I could not find an explanation for the "@" sign in the above import statement. What exactly does '@angular/core' signify in this context?

Answer №1

Utilizing '@angular/core' with the @ symbol involves accessing modules from the npm registry.

Using angular/core refers to a specific folder structure or file path.

Within Angular, '@angular/core' offers a range of pre-built functionalities. An example is when you write:

import { Component } from '@angular/core';

This enables you to utilize the component feature which encompasses

template (HTML view), class (where logic is implemented), and decorators (Angular metadata)
.

Similarly, by writing:

import { Component,Input } from '@angular/core';

You gain access to Input properties, which facilitate data transfer from the container component (parent) to the nested component (child).

Furthermore, when importing:

import { Component,Output } from '@angular/core';

You can utilize Output properties for passing data from the nested component back to the Container component.

These are just a few examples of what's possible when using imports from '@angular/core'. Refer to Angular documentation for further details on available functionalities.

Answer №2

The symbol "@" in npm enables module scoping, allowing the "core" module to be included within the "angular" namespace.
