Add user module #2
Conversation
WalkthroughThe pull request introduces environment variable placeholders, new dependencies, and several new SQL migration scripts. The migrations create and modify tables for a polling application, while the Prisma schema is updated with corresponding models. Additionally, a migration lock file is added.

🧹 Nitpick comments (8)
src/users/users.module.ts (1)
2-2: Consider using path aliases for imports.Instead of using relative paths, consider configuring and using path aliases in tsconfig.json for better maintainability.
Apply this diff:
-import { PrismaService } from 'src/prisma.service'; +import { PrismaService } from '@app/prisma.service';Add this to tsconfig.json:
{ "compilerOptions": { "paths": { "@app/*": ["src/*"] } } }src/users/users.controller.ts (1)
13-13: Fix naming convention in constructor injection.Follow NestJS conventions by using the same name for the parameter as the service type.
Apply this diff:
- constructor(private userService: UsersService) {} + constructor(private usersService: UsersService) {}prisma/migrations/20250205172850_/migration.sql (1)
1-17: Consider naming conventions and indexing strategy.
- The migration filename lacks a descriptive name, making it harder to track changes.
- The table name uses PascalCase, which might cause issues with some tools. Consider using snake_case.
- Consider adding an index on the
createdAtcolumn if you plan to query by date ranges.Apply this diff to fix the table name:
-- CreateTable -CREATE TABLE "User" ( +CREATE TABLE "users" ( "id" SERIAL NOT NULL, "worldId" TEXT NOT NULL, "username" TEXT NOT NULL, "name" TEXT NOT NULL, "createdAt" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, - CONSTRAINT "User_pkey" PRIMARY KEY ("id") + CONSTRAINT "users_pkey" PRIMARY KEY ("id") ); -- CreateIndex -CREATE UNIQUE INDEX "User_worldId_key" ON "User"("worldId"); +CREATE UNIQUE INDEX "users_worldId_key" ON "users"("worldId"); -- CreateIndex -CREATE UNIQUE INDEX "User_username_key" ON "User"("username"); +CREATE UNIQUE INDEX "users_username_key" ON "users"("username"); +-- CreateIndex +CREATE INDEX "users_createdAt_idx" ON "users"("createdAt");Also, rename the migration file to something more descriptive, like
20250205172850_create_users_table.sql.prisma/schema.prisma (3)
16-25: Add indexes and onDelete behavior to User model.Consider the following improvements:
- Add an index on
createdAtfor efficient sorting/filtering- Define onDelete behavior for the Poll relation
model User{ id Int @id @default(autoincrement()) worldId String @unique() username String @unique() profilePicture String? pollsCreatedCount Int @default(0) - createdAt DateTime @default(now()) + createdAt DateTime @default(now()) @map("created_at") @@index([createdAt(sort: Desc)]) - poll Poll[] + poll Poll[] @relation("UserPolls", onDelete: Cascade) }
43-50: Add index and onDelete behavior to Option model.Consider the following improvements:
- Add index on pollId for faster lookups
- Define onDelete behavior for relations
model Option { id Int @id @default(autoincrement()) optionText String - poll Poll @relation(fields: [pollId], references: [id]) + poll Poll @relation("PollOptions", fields: [pollId], references: [id]) pollId Int - votes Vote[] + votes Vote[] @relation("OptionVotes", onDelete: Cascade) createdAt DateTime @default(now()) + @@index([pollId]) }
52-57: Add unique constraint to Tag model.Consider adding a unique constraint on the content field to prevent duplicate tags.
model Tag{ id Int @id @default(autoincrement()) - content String? + content String? @unique - poll Poll[] + poll Poll[] @relation("PollTags") }prisma/migrations/20250205193050_initail_entities/migration.sql (2)
16-23: Add index to Option table.Add an index on pollId for better query performance when fetching options for a poll.
CREATE TABLE "Option" ( "id" SERIAL NOT NULL, "optionText" TEXT NOT NULL, "pollId" INTEGER NOT NULL, "createdAt" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, CONSTRAINT "Option_pkey" PRIMARY KEY ("id") ); +CREATE INDEX "Option_pollId_idx" ON "Option"("pollId");
1-1: Fix typo in migration filename.The migration filename contains a typo: "initail" should be "initial".
Rename the file from
20250205193050_initail_entitiesto20250205193050_initial_entities.

1-15: LGTM! Well-structured DTO with appropriate validation rules.The DTO is well-designed with proper validation decorators and consistent naming conventions.

1-10: Consider data migration strategy before dropping the name column.The migration drops the required
namecolumn without preserving or migrating the existing data. This could lead to data loss in production.Consider these options:
- If the column is no longer needed, ensure there's no valuable data before applying the migration.
- If the data needs to be preserved, create a separate migration to:
- Copy data to a new column if needed
- Make the column optional first
- Then drop it in a subsequent migration
Run this script to check if there's existing data:
❌ Verification inconclusive
🏁 Script executed:
#!/bin/bash # Description: Check if there's data in the name column before dropping it # Connect to the database and count records with non-null names psql "$DATABASE_URL" -c "SELECT COUNT(*) FROM \"User\" WHERE name IS NOT NULL;"Length of output: 161
Action Required: Manually Verify Data Preservation for the
nameColumnThe executed script did not produce output because the environment lacks the
psqlcommand, so we couldn’t automatically verify if there’s data in thenamecolumn before it’s dropped. Please run the query on an environment wherepsqlis available (for example, your production or staging database) to confirm whether any non-null data exists. If data is present, consider employing a migration strategy that preserves it (e.g., copying to a new column before dropping) to prevent potential data loss.package.json (1)
26-26:⚠️ Potential issueVerify @prisma/client version.
The specified version
^6.3.1seems incorrect as Prisma's current major version is 5.x.Update to the correct version:

🛠️ Refactor suggestion
Enhance error handling and logging.
- Use NestJS Logger instead of console.log for consistent logging across the application.
- Consider throwing the error to prevent the application from starting with a failed DB connection.
Apply this diff:
- async onModuleInit() {
- await this.$connect()
- .then(() => console.log('Connected to DB'))
- .catch((err) => console.log(err));
+ private readonly logger = new Logger(PrismaService.name);
+
+ async onModuleInit() {
+ try {
+ await this.$connect();
+ this.logger.log('Successfully connected to database');
+ } catch (error) {
+ this.logger.error('Failed to connect to database', error);
+ throw error;
+ }
}Don't forget to import Logger:
import { Injectable, Logger, OnModuleInit } from '@nestjs/common';| async createUser(data: Prisma.UserCreateInput) { | ||
| console.log(data); | ||
| return this.prisma.user.create({ data }); | ||
| } |

🛠️ Refactor suggestion
Improve error handling, logging, and type safety.
- Replace console.log with NestJS Logger
- Add error handling for database operations
- Add return type annotation
Apply this diff:
+ private readonly logger = new Logger(UsersService.name);
+
- async createUser(data: Prisma.UserCreateInput) {
- console.log(data);
- return this.prisma.user.create({ data });
+ async createUser(data: Prisma.UserCreateInput): Promise<Prisma.User> {
+ this.logger.debug('Creating user', data);
+ try {
+ return await this.prisma.user.create({ data });
+ } catch (error) {
+ this.logger.error('Failed to create user', error);
+ throw new InternalServerErrorException('Failed to create user');
+ }
}Don't forget to import:

🛠️ Refactor suggestion
Remove unused imports and fix module configuration.
- The
UsersServiceimport is unused and can be removed. - The
UsersControlleris already provided throughUsersModule, so it should be removed from thecontrollersarray to avoid duplicate registration.
Apply this diff to fix the issues:
-import { UsersService } from './users/users.service';
-import { UsersController } from './users/users.controller';
import { UsersModule } from './users/users.module';
@Module({
imports: [UsersModule],
- controllers: [AppController, UsersController],
