Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
@scalar/mock-server
Advanced tools
A powerful Node.js mock server that automatically generates realistic API responses from your OpenAPI/Swagger documents. It creates fully-functional endpoints with mock data, handles authentication, and respects content types - making it perfect for frontend development, API prototyping, and integration testing.
The easiest way to get started is through our Scalar CLI. You can have a mock server up and running in seconds:
npx @scalar/cli mock openapi.json --watch
For advanced use cases, you can integrate the mock server directly into your Node.js application for full control:
npm install @scalar/mock-server
import { serve } from '@hono/node-server'
import { createMockServer } from '@scalar/mock-server'
// Your OpenAPI document
const specification = {
openapi: '3.1.1',
info: {
title: 'Hello World',
version: '1.0.0',
},
paths: {
'/foobar': {
get: {
responses: {
'200': {
description: 'OK',
content: {
'application/json': {
example: {
foo: 'bar',
},
},
},
},
},
},
},
},
}
// Create the mocked routes
const app = await createMockServer({
specification,
// Custom logging
onRequest({ context, operation }) {
console.log(context.req.method, context.req.path)
},
})
// Start the server
serve(
{
fetch: app.fetch,
port: 3000,
},
(info) => {
console.log(`Listening on http://localhost:${info.port}`)
},
)
You can define security schemes in your OpenAPI document and the mock server will validate the authentication:
import { serve } from '@hono/node-server'
import { createMockServer } from '@scalar/mock-server'
// Your OpenAPI document
const specification = {
openapi: '3.1.1',
info: {
title: 'Hello World',
version: '1.0.0',
},
paths: {
'/secret': {
get: {
security: [
{
bearerAuth: [],
},
{
apiKey: [],
},
],
responses: {
'200': {
description: 'OK',
content: {
'application/json': {
example: {
foo: 'bar',
},
},
},
},
'401': {
description: 'Unauthorized',
content: {
'application/json': {
example: {
error: 'Unauthorized',
},
},
},
},
},
},
},
},
components: {
securitySchemes: {
bearerAuth: {
type: 'http',
scheme: 'bearer',
bearerFormat: 'JWT',
},
apiKey: {
type: 'apiKey',
in: 'header',
name: 'X-API-Key',
},
},
},
}
// Create the mocked routes
const app = await createMockServer({
specification,
// Custom logging
onRequest({ context, operation }) {
console.log(context.req.method, context.req.path)
},
})
// Start the server
serve(
{
fetch: app.fetch,
port: 3000,
},
(info) => {
console.log(`Listening on http://localhost:${info.port}`)
},
)
