Function useSpawn

Wrapper for using @45drives/cockpit-typings!spawn cockpit.spawn()

Executes process in argv on the server (or on opts.host if defined), and returns output in SpawnState.stdout

Example

import { useSpawn, errorString } from '@45drives/cockpit-helpers';

async function getHostnameAsync() {
    try {
        const state = useSpawn(['hostname'], { superuser: 'try' });
        const hostname = (await state.promise()).stdout;
        return hostname;
    } catch (state) {
        console.error(errorString(state));
        return null;
    }
}

function getHostnamePromise() {
    return new Promise((resolve, reject) => {
        const state = useSpawn(['hostname'], { superuser: 'try' });
        state.promise()
            .then(({stdout}) => resolve(stdout))
            .catch(state => {
                console.error(errorString(state))
                reject(null);
            });
    });
}
