Interface: Preconditions

The registered preconditions and their contexts, if any. When registering new ones, it is recommended to use module augmentation so custom ones are registered.

When a key's value is never, it means that it does not take any context, which allows you to pass its identifier as a bare string (e.g. preconditions: ['NSFW']), however, if context is required, a non-never type should be passed, which will type append and require an object with the name and a context with the defined type.

Example

declare module '@sapphire/framework' {
  interface Preconditions {
    // A precondition named `Moderator` which does not read `context`:
    Moderator: never;

    // A precondition named `ChannelPermissions` which does read `context`:
    ChannelPermissions: {
      permissions: Permissions;
    };
  }
}

// [✔] These are valid:
preconditions.append('Moderator');
preconditions.append({ name: 'Moderator' });
preconditions.append({
  name: 'ChannelPermissions',
  context: { permissions: new Permissions(8) }
});

// [X] These are invalid:
preconditions.append({ name: 'Moderator', context: {} });
// ➡ `never` keys do not accept `context`.

preconditions.append('ChannelPermissions');
// ➡ non-`never` keys always require `context`, a string cannot be used.

preconditions.append({
  name: 'ChannelPermissions',
  context: { unknownProperty: 1 }
});
// ➡ mismatching `context` properties, `{ unknownProperty: number }` is not
// assignable to `{ permissions: Permissions }`.
