Authentication

Hive provides auth infrastructure but no built-in auth endpoints. You implement login/signup yourself.

Built-in (in .hive/)

• tokens collection - stores access tokens
• attachUser middleware - loads user from token
• isAuthorized middleware - requires auth
• allowNoAuth middleware - skips auth

How It Works

1. Token extracted from cookie access_token or Authorization: Bearer header
2. Token looked up in tokens collection
3. User loaded from users collection
4. User attached to ctx.state.user

Token Schema (built-in)

{
  _id: string,
  user: { _id: string },
  token: string,
  metadata: object (optional),
}

Implement Auth Endpoints

1. Create token helper:

// src/resources/auth/methods/createToken.js
import db from 'db';
import crypto from 'crypto';

const tokenService = db.services.tokens;

export default async (ctx, { userId, metadata }) => {
  const token = crypto.randomBytes(32).toString('hex');
  
  await tokenService.create({
    token,
    user: { _id: userId },
    ...(metadata && { metadata }),
  });
  
  ctx.cookies.set('access_token', token, {
    httpOnly: false,
    expires: new Date(Date.now() + 10 * 365 * 24 * 60 * 60 * 1000),
  });
  
  return { token };
};

2. Login endpoint:

// src/resources/auth/endpoints/login.js
import { z } from 'zod';
import db from 'db';
import bcrypt from 'bcrypt';
import createToken from '../methods/createToken';

export const handler = async (ctx) => {
  const { email, password } = ctx.validatedData;
  
  const user = await db.services.users.findOne(
    { email },
    { isIncludeSecureFields: true }
  );
  ctx.assert(user, 401, 'Invalid credentials');
  
  const valid = await bcrypt.compare(password, user.password);
  ctx.assert(valid, 401, 'Invalid credentials');
  
  const { token } = await createToken(ctx, { userId: user._id });
  return { user, token };
};

export const middlewares = ['allowNoAuth'];
export const endpoint = { url: '/login', :  };
  requestSchema = z.({
  : z.().(),
  : z.(),
});

3. Logout endpoint:

// src/resources/auth/endpoints/logout.js
import { z } from 'zod';
import db from 'db';

export const handler = async (ctx) => {
  await db.services.tokens.remove({ token: ctx.state.accessToken });
  ctx.cookies.set('access_token', null);
  return { success: true };
};

export const endpoint = { url: '/logout', method: 'post' };
export const requestSchema = z.object({});

Users Schema (add password)

// src/resources/users/users.schema.js
password: z.coerce.string().nullable().optional(),

// Hide from responses
export const secureFields = ['password'];

Client Usage

Browser (cookies):

await fetch('/auth/login', { method: 'POST', credentials: 'include', body });

API (header):

await fetch('/tasks', { headers: { Authorization: `Bearer ${token}` } });
