Auth System Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add full authentication (register/login/logout/refresh) and role-based authorization (user/admin) to MoexVibe.

Architecture: Backend — NestJS + Prisma (SQLite) for user storage, JWT access tokens (15m) + httpOnly refresh cookies (7d) with rotation. Frontend — React context for auth state, TanStack Query for API, auto-refresh on 401 with retry.

Tech Stack: @prisma/client, @nestjs/jwt, bcrypt, cookie-parser (backend); React Context + fetch (frontend)

---

Task 1: Backend dependencies + Prisma init

Files:

• Modify: apps/backend/package.json

• Create: apps/backend/prisma/schema.prisma

• Create: apps/backend/.gitignore (or modify root)

• Create: apps/backend/src/modules/prisma/prisma.service.ts

• Create: apps/backend/src/modules/prisma/prisma.module.ts

• Step 1: Install dependencies

npm install @prisma/client @nestjs/jwt bcrypt cookie-parser -w apps/backend
npm install -D prisma @types/bcrypt @types/cookie-parser -w apps/backend

• Step 2: Init Prisma with SQLite

npx prisma init --datasource-provider sqlite

Update the generated apps/backend/prisma/schema.prisma:

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

model User {
  id           Int      @id @default(autoincrement())
  email        String   @unique
  password     String
  name         String?
  role         String   @default("user")
  refreshToken String?
  createdAt    DateTime @default(now())
  updatedAt    DateTime @updatedAt
}

• Step 3: Add DATABASE_URL to .env

DATABASE_URL="file:./dev.db"

Add .env to backend .gitignore:

node_modules/
dist/
.env
*.db
*.db-journal

• Step 4: PrismaService

// apps/backend/src/modules/prisma/prisma.service.ts
import { Injectable, OnModuleInit, OnModuleDestroy } from '@nestjs/common';
import { PrismaClient } from '@prisma/client';

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit, OnModuleDestroy {
  async onModuleInit() {
    await this.$connect();
  }

  async onModuleDestroy() {
    await this.$disconnect();
  }
}

• Step 5: PrismaModule

// apps/backend/src/modules/prisma/prisma.module.ts
import { Global, Module } from '@nestjs/common';
import { PrismaService } from './prisma.service';

@Global()
@Module({
  providers: [PrismaService],
  exports: [PrismaService],
})
export class PrismaModule {}

• Step 6: Run migration

npx prisma migrate dev --name init

• Step 7: Commit

git add apps/backend/prisma/ apps/backend/src/modules/prisma/ apps/backend/package.json apps/backend/.env apps/backend/.gitignore
git commit -m "feat: add Prisma ORM with SQLite and User model"

Task 2: AuthService — register, login, refresh, logout (TDD)

Files:

• Create: apps/backend/src/modules/auth/interfaces/jwt-payload.interface.ts

• Create: apps/backend/src/modules/auth/auth.service.spec.ts

• Create: apps/backend/src/modules/auth/auth.service.ts

• Create: apps/backend/src/modules/auth/dto/register.dto.ts

• Create: apps/backend/src/modules/auth/dto/login.dto.ts

• Create: apps/backend/src/modules/auth/dto/update-profile.dto.ts

• Step 1: Write JwtPayload interface

// apps/backend/src/modules/auth/interfaces/jwt-payload.interface.ts
export interface JwtPayload {
  sub: number;
  email: string;
  role: string;
}

• Step 2: Write DTOs

// apps/backend/src/modules/auth/dto/register.dto.ts
import { IsEmail, IsString, MinLength, MaxLength, IsOptional } from 'class-validator';
import { ApiProperty, ApiPropertyOptional } from '@nestjs/swagger';

export class RegisterDto {
  @ApiProperty({ example: 'user@example.com' })
  @IsEmail()
  email: string;

  @ApiProperty({ example: 'securePass123' })
  @IsString()
  @MinLength(6)
  @MaxLength(100)
  password: string;

  @ApiPropertyOptional({ example: 'John' })
  @IsString()
  @IsOptional()
  @MinLength(1)
  @MaxLength(100)
  name?: string;
}

// apps/backend/src/modules/auth/dto/login.dto.ts
import { IsEmail, IsString } from 'class-validator';
import { ApiProperty } from '@nestjs/swagger';

export class LoginDto {
  @ApiProperty({ example: 'user@example.com' })
  @IsEmail()
  email: string;

  @ApiProperty({ example: 'securePass123' })
  @IsString()
  password: string;
}

// apps/backend/src/modules/auth/dto/update-profile.dto.ts
import { IsString, IsOptional, MinLength, MaxLength } from 'class-validator';
import { ApiPropertyOptional } from '@nestjs/swagger';

export class UpdateProfileDto {
  @ApiPropertyOptional({ example: 'John Doe' })
  @IsString()
  @IsOptional()
  @MinLength(1)
  @MaxLength(100)

• Step 6: AuthController

// apps/backend/src/modules/auth/auth.controller.ts
import { Controller, Post, Get, Patch, Body, Req, Res, HttpCode, HttpStatus } from '@nestjs/common';
import { ApiTags, ApiOperation, ApiBearerAuth } from '@nestjs/swagger';

• Step 7: AuthModule

// apps/backend/src/modules/auth/auth.module.ts
import { Module } from '@nestjs/common';
import { JwtModule } from '@nestjs/jwt';

Task 4: Integrate AuthModule into app

Files:

• Modify: apps/backend/src/app.module.ts

• Modify: apps/backend/src/main.ts

• Modify: apps/backend/src/config/configuration.ts

• Modify: apps/backend/package.json

• Step 1: Update configuration.ts

// apps/backend/src/config/configuration.ts — add auth section
import { registerAs } from '@nestjs/config';

export default registerAs('app', () => ({
  port: parseInt(process.env.PORT || '3000', 10),
  // ... existing config ...
  auth: {
    jwtSecret: process.env.JWT_SECRET || 'dev-jwt-secret-change-in-production',
    jwtRefreshSecret: process.env.JWT_REFRESH_SECRET || 'dev-refresh-secret-change-in-production',
    jwtAccessExpires: process.env.JWT_ACCESS_EXPIRES || '15m',
    jwtRefreshExpires: process.env.JWT_REFRESH_EXPIRES || '7d',
  },
  // ... rest of config ...
}));

• Step 2: Update app.module.ts

// apps/backend/src/app.module.ts — add imports
imports: [
  ConfigModule.forRoot({ load: [configuration], isGlobal: true }),
  PrismaModule,
  CacheModule,
  MoexClientModule,
  HealthModule,
  AuthModule,
  SecuritiesModule,
  SharesModule,
  BondsModule,
  CandlesModule,
],

• Step 3: Update main.ts — add cookie-parser + Swagger bearer

// apps/backend/src/main.ts
import * as cookieParser from 'cookie-parser';

// After app creation:
app.use(cookieParser());

// Swagger config:
const config = new DocumentBuilder()
  .setTitle('MoexVibe API')
  .setVersion('1.0.0')
  .addBearerAuth()
  .build();

• Step 4: Update .env with JWT secrets

JWT_SECRET=dev-jwt-secret-change-in-production
JWT_REFRESH_SECRET=dev-refresh-secret-change-in-production
JWT_ACCESS_EXPIRES=15m
JWT_REFRESH_EXPIRES=7d

Task 5: Frontend — auth types + refactored client

Files:

• Modify: apps/frontend/src/api/responses.ts

• Modify: apps/frontend/src/api/client.ts

• Create: apps/frontend/src/api/auth.ts

• Step 1: Add auth types to responses.ts

// apps/frontend/src/api/responses.ts — add:
export interface UserResponse {
  id: number;
  email: string;
  name: string | null;
  role: string;
}

export interface AuthResponse {
  user: UserResponse;
  accessToken: string;
}

• Step 2: Refactor client.ts — add auth interceptor pattern

// apps/frontend/src/api/client.ts
import type { ApiEnvelope, ApiResponseMeta } from './responses';

const BASE = '';

let accessToken: string | null = null;
let onUnauthorized: (() => void) | null = null;

export function setAccessToken(token: string | null) {
  accessToken = token;
}

export function getAccessToken(): string | null {
  return accessToken;
}

export function setOnUnauthorized(cb: () => void) {
  onUnauthorized = cb;
}

async function request<T>(
  path: string,
  params?: Record<string, string>,
  options?: { skipAuth?: boolean },
): Promise<{ data: T; meta: ApiResponseMeta }> {
  const url = new URL(`${BASE}${path}`, window.location.origin);
  if (params) {
    for (const [k, v] of Object.entries(params)) {
      if (v !== undefined) url.searchParams.set(k, v);
    }
  }

  const headers: Record<string, string> = {};
  if (!options?.skipAuth && accessToken) {
    headers['Authorization'] = `Bearer ${accessToken}`;
  }

  const res = await fetch(url.toString(), {
    headers,
    credentials: 'include',
  });

  if (res.status === 401 && !options?.skipAuth) {
    // Try to refresh
    try {
      const refreshRes = await fetch(`${BASE}/api/v1/auth/refresh`, {
        method: 'POST',
        credentials: 'include',
        headers: { 'Content-Type': 'application/json' },
      });

      if (refreshRes.ok) {
        const refreshJson: ApiEnvelope<{ data: AuthResponse; meta: ApiResponseMeta }> = await refreshRes.json();
        const authData = refreshJson.data.data;
        setAccessToken(authData.accessToken);
        // Retry original request with new token
        headers['Authorization'] = `Bearer ${authData.accessToken}`;
        const retryRes = await fetch(url.toString(), { headers, credentials: 'include' });
        if (!retryRes.ok) throw new Error(`API error: ${retryRes.status}`);
        const retryJson: ApiEnvelope<{ data: T; meta: ApiResponseMeta }> = await retryRes.json();
        return retryJson.data;
      } else {
        setAccessToken(null);
        onUnauthorized?.();
        throw new Error('Session expired');
      }
    } catch {
      onUnauthorized?.();
      throw new Error('Session expired');
    }
  }

  if (!res.ok) throw new Error(`API error: ${res.status} ${res.statusText}`);
  const json: ApiEnvelope<{ data: T; meta: ApiResponseMeta }> = await res.json();
  return json.data;
}

// Need to import AuthResponse type
import type { AuthResponse } from './responses';

// ... rest of existing functions stay the same

• Step 3: Create auth.ts

// apps/frontend/src/api/auth.ts
import { request, setAccessToken } from './client';
import type { AuthResponse, UserResponse } from './responses';

export async function login(email: string, password: string) {
  const result = await request<AuthResponse>('/api/v1/auth/login', undefined, {
    method: 'POST',
    body: { email, password },
  });
  setAccessToken(result.data.accessToken);
  return result.data;
}

export async function register(email: string, password: string, name?: string) {
  const result = await request<AuthResponse>('/api/v1/auth/register', undefined, {
    method: 'POST',
    body: { email, password, name },
  });
  setAccessToken(result.data.accessToken);
  return result.data;
}

export async function refreshTokens() {
  const result = await request<AuthResponse>('/api/v1/auth/refresh', undefined, {
    skipAuth: true,
  });
  setAccessToken(result.data.accessToken);
  return result.data;
}

export async function logout() {
  await request<{ message: string }>('/api/v1/auth/logout', undefined, {
    method: 'POST',
  });
  setAccessToken(null);
}

export async function getMe() {
  return request<UserResponse>('/api/v1/auth/me');
}

export async function updateProfile(data: { name?: string }) {
  return request<UserResponse>('/api/v1/auth/me', undefined, {
    method: 'PATCH',
    body: data,
  });
}

Wait — I need to rethink the client.ts approach. Currently request() uses GET with query params. For POST/PATCH requests I need to handle body. Let me redesign.

Let me restructure: keep existing API functions untouched (they all use GET), and add a new authRequest function or modify request to support other methods.

I'll modify the request function signature slightly:

async function request<T>(
  path: string,
  params?: Record<string, string> | { method: string; body?: unknown },
  options?: { method?: string; body?: unknown; skipAuth?: boolean },
): Promise<{ data: T; meta: ApiResponseMeta }>

This is getting messy. Better approach: create a separate authRequest function or modify the existing request. Let me think...

Actually the cleanest approach: modify the existing request to accept an options bag with method, body, params as separate fields:

interface RequestOptions {
  params?: Record<string, string>;
  method?: string;
  body?: unknown;
  skipAuth?: boolean;
}

This way the existing callers still work with the old signature (params as second arg).

Let me plan this properly in the implementation.<｜end▁of▁thinking｜>
