Service Workers
Integration libraries to support a variety of edge networking and service worker providers.
Supported Providers
Spec maintains public Cloud Service Provider-specific npm packages to integrate with the Spec Platform.
Config
Service Workers enable seamless integration with Spec at the CDN level. Our easy-to-use libraries handle everything in the background, and integration requires just one function call, with flexible configuration options for routing traffic to the Spec Platform.
The following are the configuration options that are common to all service workers:
disableSpecProxy
Boolean
false
Enable or disable Spec processing. When disabled (true), all traffic bypasses Spec and goes directly to the customer's origin, ignoring all other settings.
inlineMode
Boolean
false
Switch between two processing modes:
Active Inline (true) routes traffic through the Spec Trust Cloud for inline mitigations.
Pass Through (false) duplicates traffic for Spec processing while sending the original directly to the customer's origin, without inline mitigations.
percentageOfIPs
Number
100
The percentage of IP addresses to route through Spec; the rest go directly to the customer's origin. Useful for gradual onboarding or rollout.
customerKey
String
none
A key from Spec to verify that traffic originates from a customer-controlled service worker.
Why Service Workers?
Service workers process data near users, reducing latency and enhancing real-time performance while optimizing bandwidth and improving security. Spec uses edge computing to route traffic from a CDN to the Spec Trust Cloud. It can either duplicate requests to Spec while sending the original to the origin server ("pass-through" mode) or forward requests directly to Spec, who in turn forwards requests to the origin server ("active" mode).
