Have a look at our [contribution guide](https://comunica.dev/contribute/). ## Development Setup _(JSDoc: https://comunica.github.io/comunica/)_ This repository should be used by Comunica module **developers** as it contains multiple Comunica modules that can be composed. This repository is managed as a [monorepo](https://github.com/babel/babel/blob/master/doc/design/monorepo.md) using [Lerna](https://lernajs.io/). If you want to develop new features or use the (potentially unstable) in-development version, you can set up a development environment for Comunica. Comunica requires [Node.JS](http://nodejs.org/) and the [Yarn](https://yarnpkg.com/en/) package manager (only when using this repo). Comunica is tested on OSX, Linux and Windows. This project can be setup by cloning and installing it as follows: ```bash $ git clone https://github.com/comunica/comunica.git $ cd comunica $ yarn install ``` **Note: `npm install` is not supported at the moment, as this project makes use of Yarn's [workspaces](https://yarnpkg.com/lang/en/docs/workspaces/) functionality** This will install the dependencies of all modules, and bootstrap the Lerna monorepo. After that, all [Comunica packages](https://github.com/comunica/comunica/tree/master/packages) are available in the `packages/` folder, and the [Comunica engines](https://github.com/comunica/comunica/tree/master/engines) are available in the `engines/` folder. These can be used in a development environment, such as querying with [Comunica SPARQL (`@comunica/query-sparql`)](https://github.com/comunica/comunica/tree/master/engines/query-sparql). Furthermore, this will add pre-commit hooks using [husky](https://www.npmjs.com/package/husky) to build, lint and test. These hooks can temporarily be disabled at your own risk by adding the `-n` flag to the commit command. ## Benchmarking If you want to do benchmarking with Comunica in Node.js, make sure to run Node.js in production mode as follows: ```bash > NODE_ENV=production node packages/some-package/bin/some-bin.js ``` Read more about benchmarking [on our website](https://comunica.dev/docs/modify/benchmarking/). ## Cite If you are using or extending Comunica as part of a scientific publication, we would appreciate a citation of our [article](https://comunica.github.io/Article-ISWC2018-Resource/). ```bibtex @inproceedings{taelman_iswc_resources_comunica_2018, author = {Taelman, Ruben and Van Herwegen, Joachim and Vander Sande, Miel and Verborgh, Ruben}, title = {Comunica: a Modular SPARQL Query Engine for the Web}, booktitle = {Proceedings of the 17th International Semantic Web Conference}, year = {2018}, month = oct, url = {https://comunica.github.io/Article-ISWC2018-Resource/} } ``` ## License This code is copyrighted by [the Comunica Association](https://comunica.dev/association/) and [Ghent University – imec](http://idlab.ugent.be/) and released under the [MIT license](http://opensource.org/licenses/MIT). --- _Source: https://npm.io/package/@comunica/query-sparql-rdfjs-lite · Machine-readable twin of the npm.io package page.
