Server configuration

The ./config/server.js file is used to define the server configuration for a Strapi application.

✋ Caution

Changes to the server.js file require rebuilding the admin panel. After saving the modified file run either yarn build or npm run build in the terminal to implement the changes.

Available options

The ./config/server.js file can include the following parameters:

Parameter	Description	Type	Default
host ❗️ Mandatory	Host name	string	localhost
port ❗️ Mandatory	Port on which the server should be running.	integer	1337
app.keys ❗️ Mandatory	Declare session keys (based on Koa session), which is used by the session middleware for the Users & Permissions plugin and the Documentation plugin.	array of strings	undefined
socket	Listens on a socket. Host and port are cosmetic when this option is provided and likewise use url to generate proper urls when using this option. This option is useful for running a server without exposing a port and using proxy servers on the same machine (e.g Heroku nginx buildpack)	string | integer	/tmp/nginx.socket
emitErrors	Enable errors to be emitted to koa when they happen in order to attach custom logic or use error reporting services.	boolean	false
url	Public url of the server. Required for many different features (ex: reset password, third login providers etc.). Also enables proxy support such as Apache or Nginx, example: https://mywebsite.com. The url can be relative, if so, it is used with http://${host}:${port} as the base url. An absolute url is however recommended.	string	''
proxy	Set the koa variable app.proxy. When true, proxy header fields will be trusted.	boolean	false
globalProxy	Defines the proxy agent for all external requests made within strapi.fetch method (used for licenses check, telemetry and webhooks). To be used if the Strapi project is behind a forward proxy.	string
cron	Cron configuration (powered by node-schedule)	object
cron.enabled	Enable or disable CRON jobs to schedule jobs at specific dates.	boolean	false
cron.tasks	Declare CRON jobs to be run at specific dates.	object
dirs	Path configuration of different directories Strapi uses.	object
dirs.public	Customize the path of the public folder.	string	./public
webhooks.populateRelations	Enable or disable receiving populated relations in webhooks	boolean	true
http	Configuration of the http server used by Strapi	object
http.serverOptions	Options passed to http createServer	http.serverOptions	{}

Configurations

The ./config/server.js minimal configuration requires the host and port parameters for development. Additional parameters can be included for a full configuration.

✏️ Note

Environmental configurations (i.e. using the env() helper) do not need to contain all the values so long as they exist in the default ./config/server.js.

The default configuration created with any new project should at least include the following:

Minimal configuration

JavaScript

./config/server.js

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  app: {
    keys: env.array('APP_KEYS'),
  },
});

TypeScript

./config/server.ts

export default ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  app: {
    keys: env.array('APP_KEYS'),
  },
});

Full configuration

The following is an example of a full configuration file. Not all of these keys are required (see available options).

JavaScript

./config/server.js

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  app: {
    keys: env.array('APP_KEYS'),
  },
  socket: '/tmp/nginx.socket', // only use if absolutely required
  emitErrors: false,
  url: env('PUBLIC_URL', 'https://api.example.com'),
  proxy: env.bool('IS_PROXIED', true),
  cron: {
    enabled: env.bool('CRON_ENABLED', false),
  },
});

TypeScript

./config/server.ts

export default ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  app: {
    keys: env.array('APP_KEYS'),
  },
  socket: '/tmp/nginx.socket', // only use if absolutely required
  emitErrors: false,
  url: env('PUBLIC_URL', 'https://api.example.com'),
  proxy: env.bool('IS_PROXIED', true),
  cron: {
    enabled: env.bool('CRON_ENABLED', false),
  },
});
