Routes

/getAllRequests			returns all requests in DB.
/getRequest/:Requestid	RequestID		returns request with specified RequestID.
/getAllAccounts			returns all accountRequests in DB.
/getAccount/:Requestid	RequestID		returns accountRequest with specified RequestID.
/getAllActivityRequests			returns all activityRequests in DB.
/getActivityRequest/:Requestid	RequestID		returns activityRequest with specified RequestID.

Validation

There are many rules to inserting data into the database, some include:

1. Request ID already exists in database.
2. Request Type not in range [1-5].
3. Request Status not in range [1-3].
4. Row data does not match any request type data structure.
5. Adding Account with permission not in database (have to add it first).
6. Adding CompanyActivity with activity not in database (have to add it first).
7. Adding Permission using a name that already exists (Permission names are unique).
8. Adding Activity using a name that already exists (Activity names are unique).

Violating any of the rules will result in omitting the row trying to insert. and no response will be provided to the front-end, the code will continue to add the following rows as long as they match the rules.

SQLite Schema

Packages, Libraries and frameworks

• BunJS: JavaScript Runtime, faster than NodeJS.
• ElysiaJS: BunJS web framework for API routes and routing.
• Sqlite and Drizzle ORM: Sqlite Database with Drizzle Object–relational mapping built to work best with TypeScript types support for maximum type safety.
