By calling delete() on QueryBuilder it only declares this query as a deletion. To execute the query you have to call execute(). See the docs for delete.

await this.tokensRepository
    .createQueryBuilder('token')
    .delete()
    .where('token.expiresOn <= :currentDate', { currentDate })
    .execute();

About the second problem: You do not have to specify the type of the variable explicitly, since it get inferred automatically.

From Repo:

• remove - Removes a given entity or array of entities. It removes all given entities in a single transaction (in the case of entity, manager is not transactional).

Example:

await repository.remove(user);
await repository.remove([
    category1,
    category2,
    category3
]);

• delete - Deletes entities by entity id, ids or given conditions:

Example:

await repository.delete(1);
await repository.delete([1, 2, 3]);
await repository.delete({ firstName: "Timber" });

As stated in example here:

import {getConnection} from "typeorm";

await getConnection()
    .createQueryBuilder()
    .delete()
    .from(User)
    .where("id = :id", { id: 1 })
    .execute();

Which means you should use remove if it contains an array of Entities.

While you should use delete if you know the condition.

Additionally, as @James stated in comment Entity Listener such as @BeforeRemove and @AfterRemove listeners only triggered when the entity is removed using repository.remove.

Similarly, @BeforeInsert, @AfterInsert, @BeforeUpdate, @AfterUpdate only triggered when the entity is inserted/updated using repository.save.

Your parameterized query looks correct.

Switch on TypeOrm Query Logging to see the generated SQL, maybe you will be able to see what's going wrong. Paste the generated SQL into the SQL query console to debug.

Alternatively you can write your delete query without parameters and let Sqlite calculate current date -1 day:

.where("tokenDate <= DateTime('Now', '-1 Day'");  // for Sqlite

Note 1: Sqlite DateTime('Now') uses UTC time, so your tokenDate should use UTC also.

Note 2: This syntax is specific to Sqlite, you can do the same in other databases but the syntax is different, e.g. Microsoft SQL Server:

.where("tokenDate <= DATEADD(day, -1, SYSUTCDATETIME());  // for MS SQL Server
