Fyper

Type-safe Cypher queries in F#. Plain records as schema, computation expressions as queries, parameterized by default.

type Person = { Name: string; Age: int }
type Movie  = { Title: string; Released: int }
type ActedIn = { Roles: string list }

let findActors = cypher {
    for p in node<Person> do
    for m in node<Movie> do
    matchRel (p -- edge<ActedIn> --> m)
    where (p.Age > 30)
    orderBy m.Released
    select (p.Name, m.Title)
}
// MATCH (p:Person) MATCH (m:Movie) MATCH (p)-[:ACTED_IN]->(m)
// WHERE p.age > $p0 ORDER BY m.released RETURN p.name, m.title

Features

  • Zero boilerplate -- F# records = graph schema
  • Compile-time safety -- quotation-based CE
  • Parameterized by default -- all values become $p0, $p1
  • Multi-backend -- Neo4j + Apache AGE from the same query
  • Zero dependencies -- only FSharp.Core

Quick Start

dotnet add package Fyper
dotnet add package Fyper.Neo4j    # or Fyper.Age

open Fyper
open Fyper.Neo4j

let driver = new Neo4jDriver(
    Neo4j.Driver.GraphDatabase.Driver("bolt://localhost:7687",
        Neo4j.Driver.AuthTokens.Basic("neo4j", "password")))

task {
    let! people = query |> Cypher.executeAsync driver
}

CE Operations

where | select | selectDistinct | orderBy | orderByDesc | skip | limit | matchRel | matchPath | create | createRel | set | delete | detachDelete | merge | onMatch | onCreate | unwind | withClause | caseWhen | count | sum | avg | collect | cypherMin | cypherMax
