📦 Installation

You can install peepDB directly from PyPI:

pip install peepdb

🛠️ Usage

peepDB uses a command-based structure for easier and more intuitive use. Here are the main commands with examples:

1. Save Your Database Connection Details

For SQLite:

peepdb save mydb --db-type sqlite --host /path/to/mydb.sqlite --database mydb

For other databases:

peepdb save <connection_name> --db-type [mysql/postgres/mariadb/mongodb/firebase] --host <host> --user <user> --password <password> --database <database>

Important Note on Password Handling: The password is required as a command-line argument. While this is convenient for scripting, it's important to note that this method can be insecure as the password may be visible in your command history or to other users who can view your screen or process list.

Example:

peepdb save myapp_db --db-type mysql --host localhost --user root --password my_secure_password --database myapp

For improved security, consider using environment variables or a configuration file to store sensitive information like passwords.

2. List Saved Connections

peepdb list

Example output:

Saved connections:
- myapp_db (mysql)
- analytics_db (postgres)

3. View Tables

View all tables:

peepdb view <connection_name>

View a specific table:

peepdb view <connection_name> --table <table_name>

Example:

peepdb view myapp_db --table users

Output:

Table: users
+----+----------+----------------------+
| id | username |        email         |
+====+==========+======================+
|  1 | johndoe  | [e-mail]  |
|  2 | janedoe  | [e-mail]  |
+----+----------+----------------------+
Page 1 of 1 (Total rows: 2)

4. Pagination

Use pagination to handle large datasets:

peepdb view <connection_name> --table <table_name> --page <page_number> --page-size <rows_per_page>

Example:

peepdb view myapp_db --table users --page 2 --page-size 50

5. Choose Output Format

Get output in JSON format:

peepdb view <connection_name> --format json

Example:

peepdb view myapp_db --table users --format json

Output:

{
  "users": {
    "data": [
      {"id": 1, "username": "johndoe", "email": "[e-mail]"},
      {"id": 2, "username": "janedoe", "email": "[e-mail]"}
    ],
    "page": 1,
    "total_pages": 1,
    "total_rows": 2
  }
}

6. Remove Saved Connections

Remove a specific connection:

peepdb remove <connection_name>

Remove all connections:

peepdb remove-all

🔒 Security

peepDB implements several security measures to protect your database connection details:

1. Local Storage: All connection details are stored locally on your machine, not on any remote servers.
2. Encryption: Connection details are encrypted before being stored, using the cryptography library.
3. Caution with Passwords: While passwords are accepted as command-line arguments for convenience, users should be cautious about using this method in shared environments or situations where command history might be accessible to others.
