lacinia

This project generates a native binary image of a simple program using lacinia, a GraphQL server implementation in pure Clojure

Usage

Configure with:

make deps

Re-run this step after changing any project dependencies.

The simple.schema class reads files from disk, so native-image must be run with the -H:ResourceConfigurationFiles option set to clinit.d/resource-config.json (as project.clj should be doing already).

More information here.

Test with:

make

The program will print the results of a simple GraphQL query.

Results

simple.main

• [com.walmartlabs.lacinia :as lacinia] ✅

simple.schema

• [com.walmartlabs.lacinia.util :as util] ✅
• [com.walmartlabs.lacinia.schema :as schema] ✅

Notes

• a GraalVM SDK from the 21.x or later series, targeting Java 11 or later, is required

• clojure 1.10.1 (and older) is affected by this known issue; the minimum required version is 1.10.2

• some unidentified transitive dependency is calling into the Java UI widget libraries, so:

  • Linux targets will need the FreeType 2 development package, in addition to the required build dependencies

  • expect a fat binary (~70 Mb on a Linux desktop, or ~55 Mb on Windows)
