Components

Above table contains these Odoo components:

  • Python environment. All Odoo server side code is written in Python. This version is very important to know what tools can be used with Odoo development.

  • PostgreSQL client. Postres is the database that stores all data in Odoo. The client version is important to be compatible with database server. Odoo will have compatibility issues if you are using too old or too new version of PostgreSQL.

  • PDF-generator wkhtml2pdf.

  • Pip package Psycopg2 used for database connection.

  • Pip package Werkzeug used for Odoo http server.

  • Pip package lxml used for XML documents.

  • Pip package watchdog used for reloading modules on file changes.

  • Pip packages xlsxwriter and xlwt used for creating Excel-files in Odoo.

  • Pip package num2words used for converting numbers to text presentation.
