This PR fix an issue with the `IsNull()` find operator applied on
one-to-many relation, this one is not supported by TypeORM.
We can instead filter by an empty array to retrieve object with empty
relations.
### Overview
This PR introduces significant enhancements to the MessageQueue module
by integrating `@Processor`, `@Process`, and `@InjectMessageQueue`
decorators. These changes streamline the process of defining and
managing queue processors and job handlers, and also allow for
request-scoped handlers, improving compatibility with services that rely
on scoped providers like TwentyORM repositories.
### Key Features
1. **Decorator-based Job Handling**: Use `@Processor` and `@Process`
decorators to define job handlers declaratively.
2. **Request Scope Support**: Job handlers can be scoped per request,
enhancing integration with request-scoped services.
### Usage
#### Defining Processors and Job Handlers
The `@Processor` decorator is used to define a class that processes jobs
for a specific queue. The `@Process` decorator is applied to methods
within this class to define specific job handlers.
##### Example 1: Specific Job Handlers
```typescript
import { Processor, Process, InjectMessageQueue } from 'src/engine/integrations/message-queue';
@Processor('taskQueue')
export class TaskProcessor {
@Process('taskA')
async handleTaskA(job: { id: string, data: any }) {
console.log(`Handling task A with data:`, job.data);
// Logic for task A
}
@Process('taskB')
async handleTaskB(job: { id: string, data: any }) {
console.log(`Handling task B with data:`, job.data);
// Logic for task B
}
}
```
In the example above, `TaskProcessor` is responsible for processing jobs
in the `taskQueue`. The `handleTaskA` method will only be called for
jobs with the name `taskA`, while `handleTaskB` will be called for
`taskB` jobs.
##### Example 2: General Job Handler
```typescript
import { Processor, Process, InjectMessageQueue } from 'src/engine/integrations/message-queue';
@Processor('generalQueue')
export class GeneralProcessor {
@Process()
async handleAnyJob(job: { id: string, name: string, data: any }) {
console.log(`Handling job ${job.name} with data:`, job.data);
// Logic for any job
}
}
```
In this example, `GeneralProcessor` handles all jobs in the
`generalQueue`, regardless of the job name. The `handleAnyJob` method
will be invoked for every job added to the `generalQueue`.
#### Adding Jobs to a Queue
You can use the `@InjectMessageQueue` decorator to inject a queue into a
service and add jobs to it.
##### Example:
```typescript
import { Injectable } from '@nestjs/common';
import { InjectMessageQueue, MessageQueue } from 'src/engine/integrations/message-queue';
@Injectable()
export class TaskService {
constructor(
@InjectMessageQueue('taskQueue') private readonly taskQueue: MessageQueue,
) {}
async addTaskA(data: any) {
await this.taskQueue.add('taskA', data);
}
async addTaskB(data: any) {
await this.taskQueue.add('taskB', data);
}
}
```
In this example, `TaskService` adds jobs to the `taskQueue`. The
`addTaskA` and `addTaskB` methods add jobs named `taskA` and `taskB`,
respectively, to the queue.
#### Using Scoped Job Handlers
To utilize request-scoped job handlers, specify the scope in the
`@Processor` decorator. This is particularly useful for services that
use scoped repositories like those in TwentyORM.
##### Example:
```typescript
import { Processor, Process, InjectMessageQueue, Scope } from 'src/engine/integrations/message-queue';
@Processor({ name: 'scopedQueue', scope: Scope.REQUEST })
export class ScopedTaskProcessor {
@Process('scopedTask')
async handleScopedTask(job: { id: string, data: any }) {
console.log(`Handling scoped task with data:`, job.data);
// Logic for scoped task, which might use request-scoped services
}
}
```
Here, the `ScopedTaskProcessor` is associated with `scopedQueue` and
operates with request scope. This setup is essential when the job
handler relies on services that need to be instantiated per request,
such as scoped repositories.
### Migration Notes
- **Decorators**: Refactor job handlers to use `@Processor` and
`@Process` decorators.
- **Request Scope**: Utilize the scope option in `@Processor` if your
job handlers depend on request-scoped services.

In this PR, I'm refactoring the messaging module into smaller pieces
that have **ONE** responsibility: import messages, clean messages,
handle message participant creation, instead of having ~30 modules (1
per service, jobs, cron, ...). This is mandatory to start introducing
drivers (gmails, office365, ...) IMO. It is too difficult to enforce
common interfaces as we have too many interfaces (30 modules...). All
modules should not be exposed
Right now, we have services that are almost functions:
do-that-and-this.service.ts / do-that-and-this.module.ts
I believe we should have something more organized at a high level and it
does not matter that much if we have a bit of code duplicates.
Note that the proposal is not fully implemented in the current PR that
has only focused on messaging folder (biggest part)
Here is the high level proposal:
- connected-account: token-refresher
- blocklist
- messaging: message-importer, message-cleaner, message-participants,
... (right now I'm keeping a big messaging-common but this will
disappear see below)
- calendar: calendar-importer, calendar-cleaner, ...
Consequences:
1) It's OK to re-implement several times some things. Example:
- error handling in connected-account, messaging, and calendar instead
of trying to unify. They are actually different error handling. The only
things that might be in common is the GmailError => CommonError parsing
and I'm not even sure it makes a lot of sense as these 3 apis might have
different format actually
- auto-creation. Calendar and Messaging could actually have different
rules
2) **We should not have circular dependencies:**
- I believe this was the reason why we had so many modules, to be able
to cherry pick the one we wanted to avoid circular deps. This is not the
right approach IMO, we need architect the whole messaging by defining
high level blocks that won't have circular dependencies by design. If we
encounter one, we should rethink and break the block in a way that makes
sense.
- ex: connected-account.resolver is not in the same module as
token-refresher. ==> connected-account.resolver => message-importer (as
we trigger full sync job when we connect an account) => token-refresher
(as we refresh token on message import).
connected-account.resolver and token-refresher both in connected-account
folder but should be in different modules. Otherwise it's a circular
dependency. It does not mean that we should create 1 module per service
as it was done before
In a nutshell: The code needs to be thought in term of reponsibilities
and in a way that enforce high level interfaces (and avoid circular
dependencies)
Bonus: As you can see, this code is also removing a lot of code because
of the removal of many .module.ts (also because I'm removing the sync
scripts v2 feature flag end removing old code)
Bonus: I have prefixed services name with Messaging to improve dev xp.
GmailErrorHandler could be different between MessagingGmailErrorHandler
and CalendarGmailErrorHandler for instance
