Usage

All exports of this package can be accessed as named imports.

// an example import
import { URLParamsHandler } from '@rnacanvas/code.url-params';

class URLParamsHandler

The URLParamsHandler class handles URL parameters for a target RNAcanvas app (see @rnacanvas/app-object).

The below example draws a structure specified in dot-bracket notation using the sequence and dot_bracket URL parameters.

targetApp; // an RNAcanvas app object

var urlParamsHandler = new URLParamsHandler(targetApp);

// a URL specifying a structure to be drawn with dot-bracket notation
var url = new URL('https://code.rnacanvas.app?sequence=GCGCAAAAGCGC&dot_bracket=((((....))))');

// draws the specified structure in the target app
urlParamsHander.handle(url.searchParams);

Schemas can also be drawn using the schema URL parameter.

// the schema to be drawn is accessible at this URL
var schemaURL = 'https://www.ebi.ac.uk/Tools/services/rest/r2dt/result/r2dt-R20240905-135809-0737-54467708-p1m/json';

var url = new URL(`https://code.rnacanvas.app?schema=${schemaURL}`);

// draws the schema
urlParamsHandler.handle(url.searchParams);
