Usage

Fastify

https://github.com/aoede3/taujs/blob/main/src/server/index.ts

Not utilising τjs [ taujs ] template? Add in your own ts alias object for your own particular directory setup e.g. alias: { object }

React 'entry-client.tsx'

https://github.com/aoede3/taujs/blob/main/src/client/entry-client.tsx

React 'entry-server.tsx'

Extended pipe object with callbacks to @taujs/server enabling additional manipulation of HEAD content from client code

Routes

Integral to τjs is its internal routing:

1. Fastify serving index.html to client browser for client routing
2. Internal service calls to API to provide data for streaming/hydration
3. Fastify serving API calls via HTTP in the more traditional sense of client/server

In ensuring a particular 'route' receives data for hydration there are two options:

1. Internal service call returning data as per your architecture
2. An HTTP call from your app passing resolved data to @taujs/server

In supporting Option 1. there is a registry of services. More detail in 'Service Registry'.

Each routes 'path' is a simple URL regex as per below examples.

Service Registry

In supporting internal calls via τjs a registry of available services and methods can provide linkage to your own architectural setup and developmental patterns
