Installation

Triplate ships as one package per language. Pick the one for your stack — they implement the same language and produce byte-identical output, verified by a shared conformance suite, so a template authored against one runs unchanged against the others. Every package has zero required runtime dependencies.

TypeScript / JavaScript

Published to npm as triplate. Ships as ES modules with bundled TypeScript types; requires Node 18+ (or any modern bundler / runtime with ESM).

Terminal window
npm install triplate
import { compile, render } from 'triplate';


const tmpl = compile('---\nparams { c: iri }\n---\n?s a ${c}');
tmpl.render({ c: 'http://example.org/Person' });
// → "?s a <http://example.org/Person>"

Python

Published to PyPI as triplate; requires Python 3.10+. The core is dependency-free. Install the optional rdflib extra only if you want to pass rdflib terms to the term type:

Terminal window
pip install triplate              # core, no dependencies
pip install "triplate[rdflib]"    # adds rdflib for the term type
from triplate import compile, render


tmpl = compile("---\nparams { c: iri }\n---\n?s a ${c}")
tmpl.render(c="http://example.org/Person")
# → "?s a <http://example.org/Person>"

Java

Published to Maven Central under dev.triplate; requires Java 17+ (the library uses records and sealed types). No runtime dependencies.

<dependency>
  <groupId>dev.triplate</groupId>
  <artifactId>triplate</artifactId>
  <version>0.3.0</version>
</dependency>
import dev.triplate.Triplate;
import java.util.Map;


String sparql = Triplate.render("---\nparams { c: iri }\n---\n?s a ${c}",
    Map.of("c", "http://example.org/Person"));
// → "?s a <http://example.org/Person>"
