Simple example of a command REPL in Node.js
const readline = require("readline");
let input = readline.createInterface({
input: process.stdin,
output: process.stdout
});
let queryCommand = () => {
input.question("Command: ", (command) => {
if (command === "exit") {
input.close();
} else {
commandHandler(command);
queryCommand();
}
});
};
let commandHandler = (command) => {
// TODO: Replace with custom command handling
console.info("User entered: " + command);
};
queryCommand();
