Phone Calls TypeDB Example (Node.js)

The Phone Calls Node.js example showcases:

1. basic migration of CSV, JSON and XML data into a TypeDB knowledge graph database
2. writing and performing expressive TypeQL queries to gain insights over the dataset

Prerequisites

• TypeDB v2.11.1
• Node.js and npm package manager (recommended version: v16.16.0 LTS)

Quickstart

1. Checkout this repository: git clone https://github.com/vaticle/typedb-driver-examples && cd typedb-driver-examples
2. Start the TypeDB Server.
3. Go to the directory where you have your typedb-all distribution unarchived, and run: ./typedb console (or typedb console, if TypeDB was installed via a package manager)
4. Load the Phone Calls schema:

> database create phone_calls
> transaction phone_calls schema write
phone_calls::schema::write> source {path-to-the-cloned-repo}/phone_calls/schema.tql
phone_calls::schema::write*> commit
> exit

5. Install dependencies: npm install.
6. Migrate the dataset into TypeDB from any of the 3 supported formats: CSV, JSON, or XML, using any one of the following commands:

• npm run migrateCsv,
• npm run migrateJson, or
• npm run migrateXml.

7. Launch the interactive query runner: npm run queries.
