Functionality

Function	Description	Param	Return
`insert<T, R = T>`	Add a new document to this collection with the specified data, assigning it a document ID automatically. When the response class is informed, the return data will be transformed to it.	`collection: string, data: T, ResponseClass?: new () => R`	`Promise<R>`
`insertWithId<T, R = T>`	Add a new document to this collection with the specified data, assigning it a document ID automatically, inserting a custom id. When the response class is informed, the return data will be transformed to it.	`collection: string, data: T, ResponseClass?: new () => R`	`Promise<R>`
`insertElementInArray`	Add a new document to this collection with the specified data, and update fields into document referred	`collection: string, id: string, arrayFieldName: string, Value: any`	`Promise`
`removeElementInArray`	Get data from a collection by id and remove the specified element in an array field	`collection: string, id: string, arrayFieldName: string, Value: any`	`Promise`
`getCollection<T, R = T>`	Get data collection that refers to the specified collection path. When the response class is informed, the return data will be transformed to it.	`collection: string, options?: Options<T>, ResponseClass?: new () => R`	`Promise<R[]>`
`getById<T, R = T>`	Get data from the collection by id.	`collection: string, id: string, ResponseClass?: new () => R`	`Promise<R>`
`getByValue<T, R = T>`	Get data collection filtered by value. When the response class is informed, the return data will be transformed to it.	`collection: string, fieldPath: string, value: any, whereFilter?: WhereFilterOp, ResponseClass?: new () => R`	`Promise<R[]>`
`getByValueOrdered<T, R = T>`	Get data collection ordinated and filtered by value. When the response class is informed, the return data will be transformed to it.	`collection: string, fieldPath: string, whereFilter: WhereFilterOp, value: any, fieldOrder: string, direction?: OrderByDirection, ResponseClass?: new () => R`	`Promise<R[]>`
`update<T>`	Updates fields in the document referred to by this DocumentReference. Note. The document ID must exist in the data sent	`collection: string, data: T`	`Promise`
`updateField<T, C = any>`	Updates fields in the document referred to by this DocumentReference in a fieldPath or nestedFields.	`collection: string, id: string, field: keyof T \\| FieldNested<T, C>, value: any`	`Promise`
`updateArray<T, C = any>`	Updates array fields in the document referred to by this DocumentReference in a fieldPath or nestedFields.	`collection: string, id: string, field: keyof T \\| FieldNested<T, C>, prevValue: any, newValue: any`	`Promise`
`remove`	Deletes the document referred to by this DocumentReference.	`collection: string, id: string`	`Promise`
`exists`	True if the document exists.	`collection: string, id: string`	`Promise`
`getSizeCollection`	Return the size of the collection.	`collection: string, options?: Options<T>`	`Promise<number>`
`getPaginatedCollection<T, F, R = T>`	Get batch data collection that refers to the specified collection path. Note: The firestore requires indexes for queries with filters and sorting, if applicable, you will need to create them. When the response class is informed, the return data will be transformed to it.	`collection: string, queryParams?: any, FilterClass?: new () => F, minimumSizeToPaginated?: number, options?: Options<T>, ResponseClass?: new () => R`	`Promise<R[]>`
`getPaginatedArray<T, A, R = A>`	Get the paginated array of a document that refers to the specified collection path.	`collection: string, id: string, field: keyof T, pageNumber: number, pageSize?: number, minimumSizeToPaginated?: number, ResponseClass?: new () => R`	`Promise<R[]>`

Transaction

Function	Description	Param
`executeTransaction<T>`	Start a new transaction. All the methods executed in transaction function will be in the transaction context and will be executed through the param transaction that is a function. Is used the runTransaction function from the Firestore database, because of this exists the same limitations. E.g, read functions can't be executed after the functions that modify data.	transaction : (t: any) => `Promise<T>`
`clearTransaction`	This method cleans the context transactional.
`setTransaction`	This method setting the transaction in the context.	`transaction: Transaction["transaction"]`

Usage

...
   const repository = this.repository;

   const transaction = async (t: any) => {
      repository.setTransaction(t);

	  const data = await repository.getById<IFake, FakeResponse>(
        dynamicallyCollection,
        "123456",
        FakeResponse,
      );

      await repository.insertWithId<IFake>(dynamicallyCollection, fake);

      await repository.remove(dynamicallyCollection, "23021990");
    };

    const response = await repository.executeTransaction(transaction);
