Angular PrimeNG InputTextArea Component

  • Last Updated : 30 Jul, 2021

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will know how to use the InputTextArea component in angular primeNG.

InputTextArea component: it is an element that is used to make a text field with multi-line input support.

Properties:

  • autoResize: We can set if the textarea size should increase on increasing the text. Textarea will not display scrollbar as the size of textarea increases. For this reason, we may need to define the row & column property.
  • disabled: We can set the textarea component to be disabled.

Events:

  • onResize: When an element resizes, a callback is invoked.

Styling:

  • p-inputtextarea: It is a directive & applied to the text input field.

Creating Angular Application & Module installation:

  • Step 1: Create an Angular application using the following command.
    ng new appname
  • Step 2: After creating your project folder i.e. appname, move to it using the following command.
    cd appname
  • Step 3: Install PrimeNG in your given directory.
    npm install primeng --save
    npm install primeicons --save

Project Structure: It will look like the following.
