JavaScript ROOT\n\nJavaScript ROOT provides interactive ROOT-like graphics in the web browsers and in `node.js`.\nData can be read and displayed from ROOT binary and JSON files.\n`JSROOT` implements user interface for THttpServer class.\n\n## Examples\n\n[![Color draw for

  let obj = await file.readObject('hpxpy;1');\n      draw('drawing', obj, 'colz');\n   \u003c/script\u003e\n...\n```\n\n### In node.js\n```javascript\nimport { openFile, makeSVG } from 'jsroot';\nimport { writeFileSync } from 'fs';\nlet file = await openFile('https://root.cern/js/files/hsimple.root');\nlet obj = await file.readObject('hpxpy;1');\nlet svg = await makeSVG({ object: obj, option: 'lego2,pal50', width: 800, height: 600 });\nwriteFileSync('lego2.svg', svg);\n```\n\n### More examples\n[Supported classes/options](https://root.cern/js/latest/examples.htm)\n\n[API examples](https://root.cern/js/latest/api.htm)\n\n\n## Install\n```\nnpm install jsroot\n```\nFor 3D rendering jsroot uses [gl](https://www.npmjs.com/package/gl) package which may have problems\nduring installation. To use jsroot without `gl` one can omit development packages:\n```\nnpm install jsroot --omit=dev\n```\n\n\n## Documentation\n[Tutorial](docs/JSROOT.md)\n\n[THttpServer](docs/HttpServer.md)\n\n[Changelog](changes.md)\n\n[Reference API](https://root.cern/js/latest/jsdoc/global.html)\n\n## Links\n[https://root.cern/js/](https://root.cern/js/)\n\n[https://jsroot.gsi.de](https://jsroot.gsi.de/)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Froot-project%2Fjsroot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Froot-project%2Fjsroot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Froot-project%2Fjsroot/lists"}
