@gasket/plugin-express NPM

@gasket/plugin-express

Adds Express to your application.

Guides

Setup Guide for adding middleware and routes.
Common "Gotchas" encountered with Express middleware.

Installation

npm i @gasket/plugin-express

Update your gasket file plugin configuration:

// gasket.js

+ import pluginExpress from '@gasket/plugin-express';

export default makeGasket({
  plugins: [
+   pluginExpress
  ]
});

Configuration

All the configurations for the plugin are added under express in the config:

compression: true by default. Can be set to false if applying compression differently.
trustProxy: Enable trust proxy option, see Express documentation on Express behind proxies

Example configuration

export default makeGasket({
  plugins: [
    pluginExpress
  ],
  express: {
    compression: false,
    trustProxy: true
  }
});

Route Definition

Routes can be defined in a in-app plugin in the plugins directory. The plugin will hook the express lifecycle to add the routes to the express app.

// plugins/routes-plugin.js
export default {
  name: 'routes-plugin',
  hooks: {
    express: async function (gasket, app) {
      app.get('/hello', (req, res) => {
        res.send('Hello World!');
      });
    }
  }
};

Lifecycles

express

Executed after the middleware event for when you need full control over the express instance.

export default {
  name: 'sample-plugin',
  hooks: {
    /**
    * Update Express app instance
    *
    * @param {Gasket} gasket The Gasket API
    * @param {Express} express Express app instance
    * @returns {function|function[]} middleware(s)
    */
    express: async function (gasket, express) {
    }
  }
};

errorMiddleware

Executed after the express event. All middleware functions returned from this hook will be applied to Express.

export default {
  name: 'sample-plugin',
  hooks: {
    /**
    * Add Express error middlewares
    *
    * @param {Gasket} gasket The Gasket API
    * @returns {function|function[]} error middleware(s)
    */
    errorMiddleware: function (gasket) {
    }
  }
};

How it works
