Terinspirasi oleh skrip yang disediakan di sini, saya membuat contoh yang dapat dikonfigurasi yang:
- dapat diatur untuk digunakan
yarnataunpm
- dapat diatur untuk menentukan perintah yang akan digunakan berdasarkan file kunci sehingga jika Anda mengaturnya untuk digunakan
yarntetapi direktori hanya memiliki package-lock.jsonitu akan digunakan npmuntuk direktori itu (default ke true).
- konfigurasikan logging
- menjalankan instalasi secara paralel menggunakan
cp.spawn
- dapat melakukan dry run agar Anda dapat melihat apa yang akan dilakukannya pertama kali
- dapat dijalankan sebagai fungsi atau dijalankan secara otomatis menggunakan env vars
- ketika dijalankan sebagai fungsi, secara opsional menyediakan larik direktori untuk diperiksa
- mengembalikan janji yang diselesaikan saat selesai
- memungkinkan pengaturan kedalaman maksimal untuk dilihat jika diperlukan
- tahu untuk berhenti berulang jika menemukan folder dengan
yarn workspaces (dapat dikonfigurasi)
- memungkinkan melewatkan direktori menggunakan env var yang dipisahkan koma atau dengan meneruskan konfigurasi array string untuk dicocokkan atau fungsi yang menerima nama file, jalur file, dan objek fs.Dirent dan mengharapkan hasil boolean.
