/**
|
|
* Create a new Change Stream, watching for new changes (insertions, updates, replacements, deletions, and invalidations) in this collection.
|
|
*
|
|
* @remarks
|
|
* watch() accepts two generic arguments for distinct use cases:
|
|
* - The first is to override the schema that may be defined for this specific collection
|
|
* - The second is to override the shape of the change stream document entirely, if it is not provided the type will default to ChangeStreamDocument of the first argument
|
|
* @example
|
|
* By just providing the first argument I can type the change to be `ChangeStreamDocument<{ _id: number }>`
|
|
* ```ts
|
|
* collection.watch<{ _id: number }>()
|
|
* .on('change', change => console.log(change._id.toFixed(4)));
|
|
* ```
|
|
*
|
|
* @example
|
|
* Passing a second argument provides a way to reflect the type changes caused by an advanced pipeline.
|
|
* Here, we are using a pipeline to have MongoDB filter for insert changes only and add a comment.
|
|
* No need start from scratch on the ChangeStreamInsertDocument type!
|
|
* By using an intersection we can save time and ensure defaults remain the same type!
|
|
* ```ts
|
|
* collection
|
|
* .watch<Schema, ChangeStreamInsertDocument<Schema> & { comment: string }>([
|
|
* { $addFields: { comment: 'big changes' } },
|
|
* { $match: { operationType: 'insert' } }
|
|
* ])
|
|
* .on('change', change => {
|
|
* change.comment.startsWith('big');
|
|
* change.operationType === 'insert';
|
|
* // No need to narrow in code because the generics did that for us!
|
|
* expectType<Schema>(change.fullDocument);
|
|
* });
