The idea behind using yargs is quite appealing.
const argv = yargs.options({
env: {
alias: 'e',
choices: ['dev', 'prod'] as const,
demandOption: true,
description: 'app environment'
}
})
.argv;
console.log(argv);
However, when I explicitly check for argv.env, TypeScript throws an error saying that there is no argv.env. How can I resolve this issue in TypeScript?
if(argv.env == "dev"){ // does not work in TypeScript
...
}
When working on this code (assuming the program does not utilize any asynchronous commands):
import yargs from 'yargs/yargs'; // <== very crucial !!!
const argv2 = yargs(process.argv.slice(2)).options({
env: {
alias: 'e',
choices: ['dev', 'prod'] as const,
demandOption: true,
description: 'app environment'
}
})
.parseSync();
console.log(argv2.env);
