Getting started

1) Build the dgraph backend binary from source [reference]

requires gcc, make, go>=1.13

git clone https://github.com/unigraph-dev/dgraph.git
cd ./dgraph
make install  # installs built binary in $GOPATH/bin

# you can view your $GOPATH by running:  go env GOPATH
# and similarly, confirm binary exists:
> ls $(go env GOPATH)/bin | grep dgraph
dgraph

2) In the unigraph project root, fetch and build project dependencies:

if you have node.js versioning issues, consider using nvm

yarn && yarn build-deps

3) Move the dgraph binary you built in step 1) to a new /opt/unigraph directory. This is a project default, but you can use a path of your choosing (as well as keep a separate data directory & bin path).

check that your user can read/write to the path(s) — you may need to e.g. chown -R $(whoami) /opt/unigraph

4) Run the backend and frontend from the unigraph project root!

the dgraph backend currently requires its default ports to be free, especially 8080.

# run backend with default data and bin path:  /opt/unigraph
./scripts start_server.sh
# or, run backend with custom paths:
./scripts/start_server.sh -d "<data directory>" -b "<dgraph binary location>"

# run frontend application in a browser:
yarn explorer-start
# or, to run as an electron application:
yarn electron-start

NOTE: if the backend failed during server initialization, you'll need a clean application state before reattempting:

• killall dgraph to kill all running dgraph processes, then
• remove p/, w/, zw/ in your data directory (by default /opt/unigraph)

Server initialization is successful upon unigraph> Unigraph server listening on port 3001 and announcing upserts.

API Keys

To use third-party API integrations, obtain desired API keys and put them in this format in a file named secrets.env.json before starting the server:

{
    "twitter": {
        "api_key": "abc",
        "api_secret_key": "abc",
        "bearer_token": "abc"
    },
    "reddit": {
        "client_id": "abc"
    },
    "openai": {
        "api_key": "abc"
    },
    "google": {
        "client_id": "abc",
        "client_secret": "abc"
    }
}
