.envfile
Running the Server
Start the server in development mode:
npm run dev
Or in production:

You can directly test any tool by running:
npm run tool <tool_name> '<json_args>'
Example:

.env.examplewith new variables
Provider Template
const BaseProvider = require('../core/BaseProvider');
class MyNewProvider extends BaseProvider {
