Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@apideck/reva 🕵

Server-side request validator for Node.js based on OpenAPI

  • Supports all OpenAPI parameters
  • Based on AJV
  • Readable and helpful errors (by @apideck/better-ajv-errors)
  • High quality TypeScript definitions included
  • Minimal footprint: 42 kB including AJV (gzip + minified)

Install

$ yarn add @apideck/reva

or

$ npm i @apideck/reva

Usage

Create a Reva instance and call the validate method with your OpenAPI operation and your request data.

import { Reva } from '@apideck/reva';

const reva = new Reva();

const result = reva.validate({
  operation, // OpenAPI operation
  request: {
    headers: { 'X-My-Header': 'value', Cookie: 'Key=Value' },
    pathParameters: { id: 'ed55e7a3' },
    queryParameters: { order_by: 'created' },
    body: { name: 'Jane Doe' },
  },
});

if (result.ok) {
  // Valid request!
} else {
  // Invalid request, result.errors contains validation errors
  console.log(result.errors);
  // {
  //   "ok": false,
  //   "errors": [
  //     {
  //       "path": "request.query",
  //       "message": "'order_by' property must be equal to one of the allowed values",
  //       "suggestion": "Did you mean 'created_at'?",
  //       "context": { "errorType": "enum", "allowedValues": ["created_at", "updated_at"] }
  //     },
  //     {
  //       "path": "request.header",
  //       "message": "request.header must have required property 'x-required-header'",
  //       "context": { "errorType": "required" }
  //     },
  //     {
  //       "path": "request.body",
  //       "message": "'name' property is not expected to be here",
  //       "context": { "errorType": "additionalProperties" }
  //     }
  //   ]
  // }

}

API

Reva

Reva is the main Request validation class. You can optionally pass options to the constructor.

new Reva(options?: RevaOptions)

Parameters

  • options: RevaOptions
    • allowAdditionalParameters?: true | OpenApiParameterType[] Allow additional parameters to be passed that are not defined in the OpenAPI operation. Use true to allow all parameter types to have additional parameters. Default value: ['header', 'cookie']
    • partialBody?: boolean Ignore required properties on the requestBody. This option is useful for update endpoints where a subset of required properties is allowed. Default value: false
    • groupedParameters?: OpenApiParameterType[] Validate multiple OpenAPI parameter types as one schema. This is useful for APIs where parameters (query,path, etc) are combined into a single parameters object. Default value: []
    • paramAjvOptions?: AjvOptions Custom AJV options for request param validation.
    • bodyAjvOptions?: AjvOptions Custom AJV options for request body validation.

reva.validate(options: RevaValidateOptions)

Validate requests based on OpenAPI. Parameter validation uses type coercion, request body validation does not. When a Content-Type header is passed, it has to match a Content-Type defined in the OpenAPI operation. Default Content-Type is application/json.

Parameters

  • options: RevaValidateOptions
    • operation: OpenApiOperation Your OpenAPI operation object to validate against
    • request: RevaRequest The request data to validate. All properties are optional
      • queryParameters?: Record<string, unknown> Query parameters to validate
      • headers?: Record<string, unknown> Headers to validate
      • pathParameters?: Record<string, unknown> Path parameters to validate
      • body?: unknown Request body to validate
    • options?: RevaOptions Override options set in the Reva constructor

Return Value

  • Result<ValidationError>
    • ok: boolean Indicates if the request is valid or not
    • errors?: ValidationError[] Array of formatted errors. Only populated when Result.ok is false
      • message: string Formatted error message
      • suggestion?: string Optional suggestion based on provided data and schema
      • path: string Object path where the error occurred (example: .foo.bar.0.quz)
      • context: { errorType: DefinedError['keyword']; [additionalContext: string]: unknown } errorType is error.keyword proxied from ajv. errorType can be used as a key for i18n if needed. There might be additional properties on context, based on the type of error.
