Neo4j OGM for TypeScript / JavaScript
We use zod to define types.
// create a driver
const driver = neo4j.driver(NEO4J_URI, neo4j.auth.basic(NEO4J_USER, NEO4J_PASSWORD));
// create a DB instance
const db = new DB(driver)
.define("User", {
name: z.string(),
email: z.string(),
FOLLOWS: MANY("User", { since: z.date() }),
POSTS: MANY("Post", { at: z.date() }),
LIKES: MANY("Post", { at: z.date() }),
})
.define("Post", {
title: z.string(),
content: z.string(),
INCLUDES: MANY("Media"),
})
.define("Media", {
url: z.string(),
type: z.string(),
size: z.bigint(),
UPLOADED_BY: ONE("User"),
});
const users = await db.create("User", [
{
name: "Jacob"
email: "hi@jacoblin.cool",
},
{
name: "Alice"
email: "alice@jacoblin.cool",
},
]);
// or if you only want to create one node
const [user] = await db.create("User", {
name: "Jacob"
email: "hi@jacoblin.cool",
});
await jacob.FOLLOWS(alice, { since: new Date() });
