# Installation

## From the Release Bundle

RecallGraph installs like any other *Foxx Microservice* inside a database, on an ArangoDB instance.

1. Download the [latest release](https://github.com/recallgraph/RecallGraph/releases/).
2. Follow the instructions in the [Foxx Deployment Manual](https://www.arangodb.com/docs/3.6/foxx-deployment.html). The web interface is the easiest, while the `foxx-cli` is more suitable for power users.

## From Source

1. Install [ArangoDB](https://www.arangodb.com/docs/stable/getting-started-installation.html) and create a database and a user with admin privileges for that database.
2. Install the *Foxx CLI*:

   ```
   $ npm install --global foxx-cli
   ```
3. Assuming the database created in step 1 above is called `rgtest` and the admin user for that database is `rguser` having password `rgpasswd`, define a server endpoint for *Foxx CLI*:

   ```
   $ foxx server set local-rgtest http://localhost:8529 -D rgtest -u rguser -P
   ```

   Enter `rgpasswd` at the prompt and press *Enter* to finish the server definition step.
4. Clone this repository:

   ```
   $ git clone https://github.com/RecallGraph/RecallGraph.git
   ```
5. Install module dependencies:

   ```
   $ npm install
   ```
6. Copy `.env.example` to `.env` and set the following values:

   ```
    ARANGO_SERVER=local-rgtest
    MOUNT_POINT=/recall
   ```

   The mounted service will be available at `http://localhost:8529/_db/rgtest/recall` after the installation is complete.
7. Install the service:

   ```
   $ npm run setup
   ```

Now that the service has been installed, you can browse its API and settings by logging into your ArangoDB instance's web API using the credentials used above and selecting the `rgtest` database. Once logged in, click on the *Services* tab in the left sidebar and you should find the *RecallGraph* service listed there.
