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

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

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:

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>"
