Simple project demonstrating the use of dgraph-js-http, a javascript HTTP client for Dgraph.

You will need to install Dgraph v21.3.2 or above and run it.

You can run the commands below to start a clean Dgraph server every time, for testing and exploration.

First, create two separate directories for dgraph zero and dgraph alpha.

mkdir -p local-dgraph-data/zero local-dgraph-data/data

Then start dgraph zero:

cd local-dgraph-data/zero
rm -r zw; dgraph zero

Finally, start the dgraph alpha:

cd local-dgraph-data/data
rm -r p w; dgraph alpha --zero localhost:5080

For more configuration options, and other details, refer to docs.dgraph.io

npm install

If your environment supports async/await, run:

node index-async-await.js

Otherwise, run:

node index-promise.js

Your output should look something like this (uid values may be different):

Created person named "Alice" with uid = 0x7569

All created nodes (map from blank node names to uids):
blank-0: 0x7569
blank-1: 0x756a
blank-2: 0x756b
blank-3: 0x756c

Number of people named "Alice": 1
{ uid: '0x7569',
  name: 'Alice',
  age: 26,
  married: true,
  loc: { type: 'Point', coordinates: [ 1.1, 2 ] },
  dob: '1980-02-01T17:30:00Z',
  friend: [ { name: 'Bob', age: 24 }, { name: 'Charlie', age: 29 } ],
  school: [ { name: 'Crown Public School' } ] }

DONE!

You can explore the source code in the index-async-await.js and index-promise.js files.
