Boar Server

Example usage for app

put these lines in your server.js

  var koa = require('koa');
  var path = require('path');
  var koaApp = module.exports = koa();
  var config = require('./config');
  var App = require('boar-server').app;

  var app = new App(koaApp);
  app.connectToMongoose(config.mongooseUri);
  app.addDynamicViewMiddleware(path.join(config.root, '/views'), config.env === 'development');
  app.addStaticContentMiddleware(path.join(config.root, '/assets'));
  app.addHookMiddleware();
  app.loadControllers(path.join(config.root, 'controllers'));
  app.loadModels(path.join(config.root, 'models'));

  if (!module.parent) { app.listen(config.port); }

Add middleware for your app

  var cors = require('koa-cors');
  var app = new App(koaApp);
  app.addMiddleware(cors());

Graceful shutdown

You can stop the server from recieving new connections with app.close(). It returns a Promise that resolves when all existing connections are ended.

  var app = new App(koaApp);
  app.listen(config.port);
  process.on('SIGTERM', () => {
    app.close().then(() => {
      // additional cleaning (e.g. closing db connection)
      process.exit(0);
    })
  })

HTTPS support

To enable HTTPS support, simple create SERVE_HTTPS environment variable with value true. The port for https will be the port of the application increased with 10000 (10k).

If you want to serve the requests with your own SSL certification, create HTTPS_KEY and HTTPS_CERT environment variables with path of the files as values.

Example

export SERVE_HTTPS=true
export HTTPS_KEY="path/to/cert.key"
export HTTPS_CERT="path/to/cert.crt"

node server.js

Build-in Middlewares

Param	Type	Description
path	String	Path to the static content's folder

  app.addStaticContentMiddleware(path);

Dynamic View

This middleware is a wrapper for koa-pug.

Param	Type	Description
path	String	Path to the pug files

  app.addDynamicViewMiddleware(path);

Method Override (koa-methodoverwrite)

  app.addMethodOverrideMiddleware();

Error Handler

Param	Type	Description
path	String	Path to error page pug template

  app.addErrorHandlerMiddleware(path);

Body Parse (koa-bodyparser)

Param	Type	Description
options	Object	More info.

  app.addBodyParseMiddleware(options);

Request Id (koa-requestid)

Param	Type	Description
options	Object	optional

Enforce SSL (koa-ssl)

Param	Type	Description
options	Object	More info.

  app.addEnforceSSLMiddleware();

If your application is running behind reverse proxy (like Heroku) you should set the trustProxy configuration option to true in order to process the x-forwarded-proto header.

  var app = new App(koaApp);
  app.addEnforceSSLMiddleware({ trustProxy: true });

Note: if you use this middleware EnforceSSL middleware should be the first you add.

Hook

  app.addHookMiddleware();

↳useNoSniff	Boolean	If true, dont-sniff-mimetype middleware will be included. Default: true

  app.addSecurityMiddlewares(options);

Default configuration

  {
    csp: {
      directives: {
