Package Exports
- prompt-async
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (prompt-async) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

prompt-async
The enhanced prompt module that enables you to await its methods.
Example Try it now!
With prompt-async
const prompt = require("prompt-async");
async function example_async() // Available only with `prompt-async`!
{
// Start the prompt.
prompt.start();
// Get two properties from the user: the `username` and `email`.
const {username, email} = await prompt.get(["username", "email"]);
// Get two properties from the user: the `password` and `food`.
const {password, food} = await prompt.get(["password", "food"]);
// Log the results.
console.log("Command-line input received: ");
console.log(` username: ${username},`);
console.log(` password: ${password},`);
console.log(` email: ${email},`);
console.log(` food: ${food}.`);
}
async function error_handling_async()
{
try
{
await example_async();
}
catch(error)
{
console.error("An error occurred: ", error);
}
}
error_handling_async();The obsolete way (causes a callback hell)
const prompt = require("prompt-async");
function example() // Still supports the obsolete way.
{
// Start the prompt.
prompt.start();
// Get two properties from the user: the `username` and `email`.
prompt.get(["username", "email"], (error, result1) => {
if(error)
{
throw Error(error);
}
// Get two properties from the user: the `password` and `food`.
prompt.get(["password", "food"], (error, result2) => {
if(error)
{
throw Error(error);
}
// Log the results.
console.log("Command-line input received: ");
console.log(` username: ${result1.username},`);
console.log(` password: ${result2.password},`);
console.log(` email: ${result1.email},`);
console.log(` food: ${result2.food}.`);
});
});
}
function error_handling()
{
try
{
example();
}
catch(error)
{
console.error("An error occurred: ", error);
}
}
error_handling();Frequently answered questions
I've been working with prompt. Do I have to modify the existing code to use this?
The only thing you have to do is to replace require("prompt") to require("prompt-async").
As you can see above, it has backward-compatibility, so it would work well with your prompt code.
However, please be aware that your prompt code pattern is discouraged, and try to use async-await pattern.
Any bugs, suggestions, or questions?
