Class ConfigProvider

A client configuration provider. It accepts configuration from both ENV variables and JSON config file. Should be created before initializing client.

• Environment variables should be prepended with DISCORD_ all upper-cased.
• JSON config properties should be snake_cased.
• You may also specify default values, for which they need to be upper-cased as well.

If multiple sources are specified, the configuration will be processed in the following order:

1. The default values.
2. The JSON config file.
3. The environment variables.

If config is repeated on multiple sources, they'll be overwritten by the latest config source.

The ConfigProvider supports array types, you can supply them through the JSON config as a direct array or through environment variables through comma-separated values.

Comma escaping is not supported yet, so if you specify a type of string[] and insert the value Hi, my name is., the value will correspond to ['Hi', ' my name is.'].

An example environment variable file would be:

DISCORD_TOKEN=MY_TOKEN
DISCORD_MY_VARIABLE=$
DISCORD_MY_NUMS=123,234,345
Copy

An example JSON config file would be:

{
  "token": "MY_TOKEN",
  "my_variable": "$",
  "my_nums": [123, 234, 345]
}
Copy

An example default object would be:

{
  TOKEN: 'MY_TOKEN',
  MY_VARIABLE: '$',
  MY_NUMS: [1, 2, 3]
}
Copy

Getting values from this config would be done by:

const token = client.config.get('TOKEN');
const myVariable = client.config.get('MY_VARIABLE');
const myNums = client.config.get('MY_NUMS');
Copy

It is also recommended specifying the types of the config. Check ConfigValidator for more information.
