Server Integrations

Jovo offers a variety of server integrations that allow you to host your apps on your own server or cloud platforms like AWS.

The following server integrations are currently working with Jovo v4:

• Express: Host your apps on your own server. This is also used for the local development server.
• AWS Lambda: Host your apps on AWS Lambda serverless functions.

Usually, a server is connected to an app config stage. For example, the development stage in app.dev.ts uses Express, which you can see in the last line of the file:

export * from './server.express';

If you add a new stage using the jovov4 new:stage <stage> command (as explained in the app config docs), the Jovo CLI prompts you to select a server integration. So, for example, if you create a new prod stage and select AWS Lambda, the following line will be added to your app.prod.ts:

export * from './server.lambda';

You can use the $server property to access specific elements from the request and response.

• getRequestHeaders
• getQueryParams
• setResponseHeaders

You can access request headers using the getRequestHeaders() method.

Jovo converts all properties to lowercase. For example, you can access the Authorization header like this:

this.$server.getRequestHeaders().authorization;

You can access query parameters using the getQueryParams() method.

this.$server.getQueryParams();

You can set additional response headers that will be merged with existing ones using the setResponseHeaders() method.

this.$server.setResponseHeaders(header: Record<string, string>);
