Project Configuration

Local development

When you're developing locally you need two pieces of information:

  1. The name of your dev deployment. This is where your functions are pushed to and served from. It is stored in the CONVEX_DEPLOYMENT environment variable. npx convex dev writes it to the .env.local file.
  2. The URL of your dev deployment, for your client to connect to. The name of the variable and which file it can be read from varies between client frameworks. npx convex dev writes the URL to the .env.local or .env file.

Production deployment

You should only be deploying to your production deployment once you have tested your changes on your local deployment. When you're ready, you can deploy either via a hosting/CI provider or from your local machine.

For a CI environment you can follow the hosting docs. npx convex deploy run by the CI pipeline will use the CONVEX_DEPLOY_KEY, and the frontend build command will use the deployment URL variable, both configured in your CI environment.

You can also deploy your backend from your local machine. npx convex deploy will ask for a confirmation and then deploy to the production deployment in the same project as your configured development CONVEX_DEPLOYMENT.


Additional project configuration can be specified in the convex.json file in the root of your project (in the same directory as your package.json).

The file supports the following configuration options:

Changing the convex/ folder name or location

You can choose a different name or location for the convex/ folder via the functions field. For example, Create React App doesn't allow importing from outside the src/ directory, so if you're using Create React App you should have the following config:

"functions": "src/convex/"

Installing packages on the server

You can specify which packages used by Node actions should be installed on the server, instead of being bundled, via the node.externalPackages field. Read more.

Importing the generated functions API via require() syntax

The Convex code generation can be configured to generate a CommonJS-version of the _generated/api.js file via the generateCommonJSApi field. Read more.
