Login with Cookies:

var { login } = require('@hoahenry/meta-api');
var { readFileSync } = require('fs');
var cookies = JSON.parse(readFileSync('path_to_cookies.json'));

login({ cookies: cookies }, async function(error, api) {
    if (error) console.log(error);
    else console.log(api);
    // You can use API here
});

var { login } = require('@hoahenry/meta-api');

login({ email: 'your_email_or_facebook_id', password: 'your_password' }, async function (error, api) {
    if (error) console.log(error);
    else console.log(api);
    // You can use API here
});

Or use both methods:

var { login } = require('@hoahenry/meta-api');
var { readFileSync } = require('fs');
var cookies = JSON.parse(readFileSync('path_to_cookies.json'));

function loginHandle(error, api) {
    if (error) return login({ email: 'your_email_or_facebook_id', password: 'your_password' }, loginHandle);
    // You can use API here
}

login({ cookies }, loginHandle);
