zod-validation-error
Wrap zod validation errors in user-friendly readable messages.
Features
- User-friendly readable messages, configurable via options;
- Maintain original errors under
error.details
; - Extensive tests.
Installation
npm install zod-validation-error
Requirements
- Node.js v.14+
Quick start
// create zod schema
const zodSchema = zod.object({
id: zod.number().int().positive(),
email: zod.string().email(),
});
// parse some invalid value
try {
zodSchema.parse({
id: 1,
email: 'foobar', // note: invalid email
});
} catch (err) {
const validationError = fromZodError(err);
// the error now is readable by the user
// you may print it to console
// or return it via an API
console.log(validationError);
}
Motivation
Zod errors are difficult to consume for the end-user. This library wraps Zod validation errors in user-friendly readable messages that can be exposed to the outer world, while maintaining the original errors in an array for dev use.
Example
Input (from Zod)
[
{
"code": "too_small",
"inclusive": false,
"message": "Number must be greater than 0",
"minimum": 0,
"path": ["id"],
"type": "number"
},
{
"code": "invalid_string",
"message": "Invalid email",
"path": ["email"],
"validation": "email"
}
]
Output
Validation error: Number must be greater than 0 at "id"; Invalid email at "email"
