The simplest possible Replicache backend - integrates Replicache with an array :).

Replicache Echo Backend

This is maybe the simplest possible example of a Replicache backend.

It's completely in-memory. All state will be lost when it exits.

To learn more about the Replicache protocol, and how to connect to your own backend, see Replicache Server Setup.

For a more real-life example of a backend integration, see replicache-sample-todo.

Setup

npm install

Run

node .

Your Replicache endpoints are:

• http://localhost:3001/replicache-client-view
• http://localhost:3001/replicache-batch

Example Usage

curl -X POST -d '{"clientID":"1", "mutations":[{"id":1,"name":"foo","args":"42"}]}' -H "Content-type: application/json" http://localhost:3001/replicache-batch
curl -X POST -d '{"clientID":"1", "mutations":[{"id":2,"name":"bar","args":"true"}]}' -H "Content-type: application/json" http://localhost:3001/replicache-batch

curl -X POST -d '{"clientID":"1"}' -H "Content-type: application/json" http://localhost:3001/replicache-client-view

Outputs:
