Cypher Builder is a JavaScript programmatic API to create [Cypher](https://neo4j.com/docs/cypher-manual/current/) queries for [Neo4j](https://neo4j.com/).

- [Documentation](https://neo4j.github.io/cypher-builder/cypher-builder/current/)

```typescript

import Cypher from "@neo4j/cypher-builder";

const movieNode = new Cypher.Node();

const pattern = new Cypher.Pattern(movieNode, { labels: ["Movie"] });

const matchQuery = new Cypher.Match(pattern)

    .where(movieNode, {

        title: new Cypher.Param("The Matrix"),

    })

    .return(movieNode.property("title"));

const { cypher, params } = matchQuery.build();

console.log(cypher);

console.log(params);

```

_Cypher_

```cypher

MATCH (this0:Movie)

WHERE this0.title = $param0

RETURN this0.title

```

_Params_

```typescript

{

    "param0": "The Matrix",

}

```
