README

SPA

An HTTP server for a single page application in JavaScript.

An example of an index HTML page, a loader in JavaScript and a CSS style sheet are included. A favicon file using the PNG format is also included for reference.

Building

Use the build.bat script included with the source code.

Installation

go install github.com/vault-thirteen/SPA/cmd/spaServer@latest

Startup Parameters

Server

spaServer.exe <path-to-configuration-file>
spaServer.exe

Example:

spaServer.exe "settings.txt"
spaServer.exe

Notes:
If the path to a configuration file is omitted, the default one is used.
Default name of the configuration file is settings.txt.

Settings

Format of the settings' file for a server is quite simple. It uses line breaks as a separator between parameters. Described below are meanings of each line.

1. Server's hostname.
2. Server's listen port.
3. Work mode: HTTP or HTTPS.
4. Path to the certificate file for the HTTPS work mode.
5. Path to the key file for the HTTPS work mode.
6. TTL of served files, i.e. value of the max-age field of the Cache-Control HTTP header.
7. Allowed origin for HTTP CORS, i.e. value of the Access-Control-Allow-Origin HTTP header.
8. List of the cached files related to the JavaScript single page application, except the index HTML page which is hardcoded – a JavaScript loader script, a CSS style sheet and a favicon file.

Notes:
This server is an SPA server. This means that it does not serve ordinary data files having the contents of the whole website. It serves only those files which are required to start the JavaScript SPA itself and no more.
