Before & After

See the kind of fixes Temper generates automatically

Before — SQL Injection + Plain Text Password

// No input validation
app.post('/api/users', (req, res) => {
  const { email, password } = req.body;
  db.query(`INSERT INTO users 
    VALUES ('${email}', '${password}')`);
  res.json({ ok: true });
});

After — Validated + Parameterized + Hashed

// Validated + parameterized
app.post('/api/users',
  validate(UserSchema),
  async (req, res) => {
    const { email, password } = req.body;
    const hash = await argon2.hash(password);
    await db.query(
      'INSERT INTO users VALUES ($1, $2)',
      [email, hash]
    );
    res.json({ ok: true });
});
