RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including express-openapi-validate. Try it out:
const jsYaml = require("js-yaml");
const {
OpenApiValidator,
ValidationError,
} = require("express-openapi-validate");
const openApiDocument = jsYaml.safeLoad(`
openapi: 3.0.1

/echo:

`);
const validator = new OpenApiValidator(openApiDocument);
// This is the express middleware that does the validation
const validate = validator.validate("post", "/echo");
const fakeRequest = {
body: {},
query: {},
headers: {},
cookies: {},
params: {},
};
const fakeResponse = {};
const nextFunction = (err) => {
console.log("Error passed to next:", err);
};
validate(fakeRequest, fakeResponse, nextFunction);
const requestWithBody = Object.assign({}, fakeRequest, {
body: { input: "Hello!" },
});
validate(requestWithBody, fakeResponse, nextFunction);
