Does the Fastify.js have trouble with complicated Regex patterns?

[hessaam]

I declare a simple API route in routes/api/user/v1.0 directory in the index.js file as below:

"use strict";

const { userRegistration } = require("../../../../controller/user/userRegistrationV1");
const createUserFirstVersionSchema = require("../../../../schemas/userRegistrationSchema")

const { authenticator } = require("../../../../handler/auth");

module.exports = async function (fastify, opts) {
  fastify.post("/", { preValidation: authenticator, schema: {body: createUserFirstVersionSchema} }, userRegistration);
  }

This is createUserFirstVersionSchema:

const createUserFirstVersionSchema = {
  type: "object",
  properties: {
    name: { type: "string", minLength: 2, maxLength: 30 },
    family: { type: "string", minLength: 2, maxLength: 30 },
    username: { type: "string", minLength: 2, maxLength: 30, pattern: "^[a-zA-Z0-9_]+$" },
    password: {
      type: "string",
      pattern: "^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[~@#_^*%/.+:;=])[A-Za-z\d~@#_^*%/.+:;=]{8,}$",
    },
    roleName: { type: "string" },
    roleId: {
      type: "string",
      pattern:
        "^[0-9a-fA-F]{8}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{12}$",
    },
    type: { type: "string", enum: ["Person", "Company"] },
    status: { type: "string", enum: ["active", "inactive"] },
  },
  required: ["name", "family", "username", "password", "roleId", "type", "status"],
};

module.exports = createUserFirstVersionSchema;

And here is my request cURL:

curl --location 'http://localhost:2000/api/user/v1.0' \

--header 'Content-Type: application/json' \
--header 'Authorization: Bearer xxxx' \
--data-raw '{
    "name": "John",
    "family": "Doe",
    "username": "John_Doe",
    "password": "soheKKyl@2W",
    "type": "Person"
}

As you can see the sent request has a valid password and I expect an error to occur for the lack of roleId but this error occurred:

{
    "code": "VALIDATION_ERROR",
    "message": "Request validation failed",
    "errors": [
        {
            "field": "password",
            "message": "should match pattern \"^(?=.*[a-z])(?=.*[A-Z])(?=.*d)(?=.*[~@#_^*%/.+:;=])[A-Za-zd~@#_^*%/.+:;=]{8,}$\""
        }
    ]
}

Does the Fastify.js have trouble with complicated Regex patterns?

• node version: 20.2.0
• fastify version: 3.21.3

Potential issue when using the regex to validate in fast-json-stringify?

[hessaam]

I created the project with Fastify-CLI. Does it need additional packages?

[metcoder95]

Did you try the scenario using a custom ajv instance?
As well, maybe if print out the password value on the preValidation hook, you might have an idea of what are you receiving after parsing the request
