Host an instance of Silex

If you plan to host Silex for your clients, your users or the community, this section is for you.

If you feel like helping and host an instance of Silex as an alternative to the official Silex site please let us know so that we can advertise it to the community.

You will need a nodejs server, which you can setup yourself or host at heroku or Gandi for example (may be free of charge for small traffic, even with your own domain name).

Download the zip file on github or clone this repository, and then follow the same steps as the developers when they install silex locally on linux - starting at npm install. See instructions bellow.

Installation on your local computer

This is for developers only, since our beloved designers can use the online version.

Developers you can clone this repository and start Silex, with nodejs. See instructions bellow.

Recommended: with Docker

Prerequisite :

$ docker run -p 6805:6805 indiehosters/silex

Open http://localhost:6805/ and you are ready!

local installation on linux or macos or cloud9


Clone this repository, and do not forget the sub modules (cloud-explorer and unifile)

$ git clone --recursive

Install all needed modules

$ npm install

Start the server and then open http://localhost:6805/ - note that the port is 6805, which is easy to remember, since it is the date of sexual revolution started in paris france 8-)

$ npm start

Note for cloud9 users: you may want to activate python with this command:

$ nada-nix install python

  • Open your favorite browser on http://localhost:6805/ and ENJOY !!!
  • also take a look at the "available commands" section bellow

Available commands

If you develop or debug Silex, these npm scripts can be used with npm (they are defined in the file package.json)

  • $ npm start will start the server
  • $ npm run start:debug will start the server in debug mode (no error catchall, enable local service to use local file system as a storage)
  • $ npm run build will build the client side code (html, css, js), ready for production
  • $ npm run build:server this only check that the server scripts are correct
  • $ npm run watch:client will watch the html, js and css source folders and rebuild when a file changes

environment variables

  • PORT

enable https / SSL

When you start Silex, it looks for the environment variables SILEX_SSL_PRIVATE_KEY and SILEX_SSL_CERTIFICATE. If they are present, it enables SSL.

SILEX_SSL_PRIVATE_KEY is expected to be the path to a .key file, and SILEX_SSL_CERTIFICATE the path to a .crt.
