Simple and safe code for converting express-style paths to URLs

pathToUrl.js

/**
 *
 * @param {String} path - express-style path
 * @param {Object} params
 * @returns {String}
 *
 * @example pathToUrl('/users/:userId', { userId: 10 }) -> '/users/10'
 */
export const pathToUrl = (path, params) => {
    return path.replace(/:(\w+)/g, (match, str) => {
        if (!params[str]) {
            throw new TypeError(`No param for path match "${match}".`);
        }

        return params[str];
    });
};

// pathToUrl('/lab/sample/:sampleId/analysis/:analysisId', { sampleId: 10, analysisId: 20 });
// -> "/lab/sample/10/analysis/20"

// pathToUrl('/users/:userId', { userId: 10 }) 
// -> '/users/10'
