Add a schema to TerminusDB and TerminusCMS using the TerminusDB JavaScript Client

Add a Schema

After you have imported the terminusdb_client, and created a client, and connected to a database you can create a schema.

Create a schema

You can create a JSON schema, in this example we'll create a schema with one object called Player with two properties name and position with the name forming the lexical key:

const schema = { "@type" : "Class",
                 "@id"   : "Player",
                 "@key"  : { "@type": "Lexical", "@fields": ["name"] },
                 name    : "xsd:string",
                 position: "xsd:string" };

Add the schema

Add the schema object with:

const addSchema = async () => {
  const result = await client.addDocument(schema,  { graph_type: "schema" });
  console.log("the schema has been created", result)
}
