Adding middlewares on the server

Catalyst offers a flexible approach to defining server-side code, granting you greater control and customization over server operations.

Steps to add a middleware on the server

• To modify the server behavior, create a file named server.js within the server directory of your app.
• Define a function named addMiddlewares, which receives the app server instance as a parameter. Catalyst provides this instance when executing the function on the server.
• Use the app parameter to configure middleware for your application.

server/server.js

export function addMiddlewares(app) {
  // server code
}

This express server instance enables you to integrate middleware, logging, and handle incoming requests effectively.

Adding middlewares

Integrating middleware follows a familiar process, like traditional Node.js servers.

server/server.js

export function addMiddlewares(app) {
  app.use(path, middleware)
  app.use(path, middleware)
  app.use(path, middleware)
}

Example

server/server.js

import logger from logger

export function addMiddlewares(app) {
  app.use("*", logger)
}
