Supplychain for resolving digger contracts
npm install digger-clientdigger-client
=============
Connect to a digger server and run selectors
``
$ npm install digger-client
`js
// the supplychain is what connects our digger client with the transport
var supplychain = require('digger-client')();
// the transport is a function that handles the request and response streams
// this can move them over a network or pass them to a local digger server
supplychain.on('request', function(req, res){
// req is a readable stream
// res is a writable stream
})
`
Or make a HTTP connected client:
`js`
var supplychain = require('digger-client').http('http://localhost:8080/digger');
Now we have a supplychain hooked up to a transport - we can create containers:
`js`
// connect to a warehouse on a path
var warehouse = supplychain.connect('/my/warehouse');
ship requests can send complicated contracts with multiple inputs but cannot stream
they collect all the results into an array and pass them to your callback:
`js`
// run a selector to that warehouse
warehouse('product[price<100]')
.ship(function(products){
console.log(products.count() + ' products loaded');
})
stream requests can send only one source of input but can stream
`js
warehouse('product[price<100]')
.stream()
.through(function(model){
console.dir(model);
})
