Assalamu'alaikum warahmatullahiwabarokatuh, selamat malam teman-teman :D,
pada postingan kali ini saya akan berbagi cara membuat CRUD sederhana dengan firebase dan javascript yang di kombinasikan dengan bootstrap css framework, pertama teman2 harus download bootstrap dulu, atau kalau sudah punya file-nya tidak perlu download :D, untuk mengikuti tutorial ini teman-teman harus punya account firebase jika belum langsung saja daftar atau lihat DISINI cara membuat account firebase.
ok, teman2 buat folder dengan nama firebasejs atau apa saja terserah teman2, copy kan folder (css, js, fonts) yang ada pada bootsrap teman2 kedalam folder firebasejs. Setelah itu buat file baru didalam folder firebasejs dengan nama index.html dan tuliskan source code seperti berikut :
<!DOCTYPE html>
<html>
<head>
<title>CRUD Firebase</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<!-- Bootstrap CSS -->

projectId: "exam-aff8f",

};
firebase.initializeApp(config);
