🚀 feat: Add Gemini 2.0 Support, Update Packages and Deprecations

[danny-avila]

Summary

I added support for the Gemini 2.0 model, updated Express to address a security vulnerability, specified the .env file in the launch configuration, and fixed deprecated MongoDB functions and options.

• Added Gemini 2.0 support:

  • Updated .env.example to include gemini-2.0-flash-exp in GOOGLE_MODELS.
  • Added 'gemini-2.0' to tokenValues in api/models/tx.js.
  • Added 'gemini-2.0' to googleModels in api/utils/tokens.js.
  • Bumped the version in packages/data-provider/package.json to 0.7.59.
  • Added 'gemini-2.0' to visionModels in packages/data-provider/src/config.ts.

• Updated Express to version 4.21.2 to address CVE-2024-52798:

  • Modified api/package.json to update Express from ^4.21.1 to ^4.21.2.
  • TBD any breaking changes
    • Unpatched path-to-regexp ReDoS in 0.1.x (CVE-2024-52798, CVE-2024-45296) expressjs/express#6216

• Specified the .env file in the launch configuration:

  • Added "envFile": "${workspaceFolder}/.env" in .vscode/launch.json.

• Fixed deprecated MongoDB functions and options:

  • Replaced deprecated count() with countDocuments() in config/user-stats.js.
  • Commented out deprecated MongoDB connection options useNewUrlParser and useUnifiedTopology in api/lib/db/connectDb.js.

Change Type

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Testing

I tested the addition of the Gemini 2.0 model by initiating conversations using the new model and verifying that responses are generated correctly. I ensured that the application runs without warnings or errors due to the updated dependencies and deprecated function replacements. I confirmed that the MongoDB connections work successfully without the deprecated options and that counting functions return correct results. I also verified that the .env file is correctly loaded in the launch configuration.

Test Configuration:

• Operating System: Ubuntu 22.04 LTS
• Node.js Version: 18.x
• MongoDB Version: 6.x
