# Configurations

The application configuration lives in the ./config folder (see project structure). All the configuration files are loaded on startup and can be accessed through the configuration provider.

If the ./config/server.js file has the following config:

module.exports = {
  host: '',

The server.host key can be accessed as:

strapi.config.get('server.host', 'defaultValueIfUndefined');

Nested keys are accessible with the dot notation (opens new window).


The filename is used as a prefix to access the configurations.

Configuration files can either be .js or .json files.

When using a .js file, the configuration can be exported:

  • either as an object:

    module.exports = {
      mySecret: 'someValue',
  • or as a function returning a configuration object (recommended usage). The function will get access to the env utility:

    module.exports = ({ env }) => {
      return {
        mySecret: 'someValue',
