Setting Up Your Environment

Before diving into coding, setting up your local environment is key. Here's what you need to do:

1. In the root directory, locate the sample.config.toml file.
2. Rename it to config.toml and fill in the necessary configuration fields.
3. Run npm install to install all dependencies.
4. Run npm run db:push to set up the local sqlite database.
5. Use npm run dev to start the application in development mode.

Please note: Docker configurations are present for setting up production environments, whereas npm run dev is used for development purposes.

Coding and Contribution Practices

Before committing changes:

1. Ensure that your code functions correctly by thorough testing.
2. Always run npm run format:write to format your code according to the project's coding standards. This helps maintain consistency and code quality.
3. We currently do not have a code of conduct, but it is in the works. In the meantime, please be mindful of how you engage with the project and its community.

Following these steps will help maintain the integrity of Perplexica's codebase and facilitate a smoother integration of your valuable contributions. Thank you for your support and commitment to improving Perplexica.
