Move all Gmail API calls into gmail utils folder

Move all Gmail API calls into gmail utils folder

Currently some Gmail API calls are scattered throughout the app. All Gmail API interactions should live in apps/web/utils/gmail/.

Search the project for .gmail. and you'll see all the places we're calling the Gmail API outside of the apps/web/utils/gmail/ folder.

Unifying this into the gmail folder, will make it easier to add Outlook integration.

Examples

Good (already in gmail folder):

// apps/web/utils/gmail/message.ts
export async function getMessage(
  messageId: string,
  gmail: gmail_v1.Gmail,
  format?: "full" | "metadata",
): Promise<MessageWithPayload>

Need to fix (currently outside gmail folder):

// Found in app code
const response = await gmail.users.messages.list({
  userId: "me",
  labelIds: type === "OTHER" ? undefined : [type],
  maxResults: 5,
  q: getQuery(type),
  pageToken,
});

Tasks

1. Find all direct Gmail API calls outside the gmail folder
2. Create corresponding functions in gmail folder
3. Replace direct API calls with these functions
4. Remove any unused direct Gmail imports

Done when

• All Gmail API calls happen through functions in apps/web/utils/gmail/
• No direct Gmail API usage outside this folder
