Use meta for response headers, contentType, statusCode...etc

[icebob]

Since Moleculer v.012 ctx.meta comes back to the caller. It means requests send context meta information back to API Gateway, like response status code, response headers, response content type...etc.

Meta keys what API Gateway will process:

• ctx.meta.$responseType - set Content-Type in response
• ctx.meta.$responseHeaders - set custom response headers
• ctx.meta.$responseStatus - set HTTP status code in response
• ctx.meta.$location - redirect location when the $responseStatus is 3xx

Example

{
    exportData(ctx) {
        // Set meta for API GW
        ctx.meta.$responseStatus = 200;
        ctx.meta.$responseType = "text/csv; charset=utf-8";
        ctx.meta.$responseHeaders = {
            "Content-Disposition": 'attachment; filename=\"data.csv\"'
        }

        // Return data
        return this.getAllRows();
    }
}
