The Input prompt is a simple text input with support for auto suggestions.

The Input prompt can be imported from prompt/mod.ts or prompt/input.ts.

import { Input } from "";

const name: string = await Input.prompt("What's your github user name?");Copy
$ deno run --unstable


The Input prompt implements all base and auto suggestion options and the following prompt specific options.

Min input length

The minLength option specifies the minimum length of the input value. Default is 0.

Max input length

The maxLength option specifies the maximum length of the input value. Default is infinity.

List pointer

With the listPointer you specify the list pointer icon. Default is .

Display usage info

The info option enables the info bar which displays some usage information.

Auto suggestions

Tab-completions can be enabled with the suggestions and/or id option. If an id is provided, the value will be saved to the local storage using the id as local storage key. With suggestions you can provide some default suggestions. Both options can be defined at the same time. You can read more about auto suggestions here.


❕ The id option requires deno >= 1.10 and the --location flag. Since deno 1.16.0 the --location flag is optional.
