Middlewares

Overview

Middlewares is a simple wrapper around the required middlewares for an express app at maon.

Usage

Just like above:

import middlewares from '@maon/middlewares';
import express from 'express';

const app = express();

app.use(middlewares());

Import the module and use it. It works with CJS require as well.

Included packages

• Pino
• Helmet
• BodyParser with configuration for json and urlencoded encoding
• Cors
• ExpressValidator
• ServiceVersion

Configuration

All the included modules are imported with standard options but you can customize them by passing in an object

import middlewares from '@maon/middlewares';
import express from 'express';

const app = express();

app.use(middlewares({
    cors: {
        origin: 'http://example.com,
    },
}));

All configuration options in the documentations of the modules are available. If you want to disable a certain module, just pass in false as an option:

middlewares({
  cors: false,
});

The configurations are accessible via the names:

• pino
• helmet
• validator
• bodyParserJson
• bodyParserUrl
• serviceVersion
• cors

Logger

To use the integrated logging function with the included request object write the following call:

app.get('/', (request, response) => {
  try {
    // Some working
  } catch (error) {
    request.log.error(error);
  }
});

Have fun coding!
