A node wrapper for the DMOJ API. https://dmoj.ca

Example

const dmoj = new (require('dmoj'))();

(async () => {
    /**
     * Fetches an uncached problem
     */
    console.log((await dmoj.getProblem('cco15p1')).name); //CCO '15 P1 - Hungry Fox

    /** 
     * Creates a cache of problems
     */
    const problems = await dmoj.getProblems();

    /**
     * dmoj.getProblem is essentially just a promisified version of problems.get
     * The only difference is that dmoj.getProblem can fetch uncached problems,
     * while dmoj.getProblem can be called without doing dmoj.getProblems first.
     */

    console.log(problems.get('cco15p1').name);            //CCO '15 P1 - Hungry Fox
