How do I set a minimum value for a decimal in express-validator

I'm trying to validate my body on a express route and having trouble trying to figure out how to enforce a minimum value for a decimal. I've tried

check("price").exists().isDecimal({min:0})

and

check("price").exists().isDecimal({gt:0})

but neither seems to work

Solution

  • You could try using isFloat(..):

    console.log(validator.isFloat("7", {min: 5}));
console.log(validator.isFloat("3", {min: 5}));
console.log(validator.isFloat("5.9995", {min: 5}));
console.log(validator.isFloat("1.5", {min: 5}));
console.log(validator.isFloat("-1", {min: 0}));
