## Config file locations
# Formats
Vikunja supports using `toml`, `yaml`, `hcl`, `ini`, `json`, envfile, env variables and Java Properties files.
We reccomend yaml or toml, but you're free to use whatever you want.
Vikunja provides a default [`config.yml`](https://kolaente.dev/vikunja/api/src/branch/master/config.yml.sample) file which you can use as a starting point.
# Config file locations
Vikunja will search on various places for a config file:

# Default configuration with explanations
This is the same as the `config.yml.sample` file you'll find in the root of vikunja.
The following explains all possible config variables and their defaults.
You can find a full example configuration file in [here](https://code.vikunja.io/api/src/branch/master/config.yml.sample).
{{< highlight yaml >}}
service:
# This token is used to verify issued JWT tokens.
# Default is a random token which will be generated at each startup of vikunja.
# (This means all already issued tokens will be invalid once you restart vikunja)
JWTSecret: "cei6gaezoosah2bao3ieZohkae5aicah"
# The interface on which to run the webserver
interface: ":3456"
# The URL of the frontend, used to send password reset emails.
frontendurl: ""
# The base path on the file system where the binary and assets are.
# Vikunja will also look in this path for a config file, so you could provide only this variable to point to a folder
# with a config file which will then be used.
rootpath: <the path of the executable>
# The max number of items which can be returned per page
maxitemsperpage: 50
# If set to true, enables a /metrics endpoint for prometheus to collect metrics about the system
# You'll need to use redis for this in order to enable common metrics over multiple nodes
enablemetrics: false
# Enable the caldav endpoint, see the docs for more details
enablecaldav: true
# Set the motd message, available from the /info endpoint
motd: ""
# Enable sharing of lists via a link
enablelinksharing: true
# Whether to let new users registering themselves or not
enableregistration: true
# Whether to enable task attachments or not
enabletaskattachments: true
# The time zone all timestamps are in

# Whether task comments should be enabled or not
enabletaskcomments: true
# Whether totp is enabled. In most cases you want to leave that enabled.
enabletotp: true
# If not empty, enables logging of crashes and unhandled errors in sentry.
sentrydsn: ''
If you don't provide a value in your config file, their default will be used.
database:
# Database type to use. Supported types are mysql, postgres and sqlite.
type: "sqlite"
# Database user which is used to connect to the database.
user: "vikunja"
# Databse password
password: ""
# Databse host

## Nesting
cache:

enabled: false

maxelementsize: 1000
Most config variables are nested under some "higher-level" key.
For example, the `interface` config variable is a child of the `service` key.
redis:
# Whether to enable redis or not
enabled: false
# The host of the redis server including its port.
host: 'localhost:6379'
# The password used to authenicate against the redis server
password: ''
# 0 means default database
db: 0
The docs below aim to reflect that leveling, but please also have a lookt at [the default config](https://code.vikunja.io/api/src/branch/master/config.yml.sample) file
to better grasp how the nesting looks like.
cors:
# Whether to enable or disable cors headers.
# Note: If you want to put the frontend and the api on seperate domains or ports, you will need to enable this.
# Otherwise the frontend won't be able to make requests to the api through the browser.
