How to use the graphlib.alg.dijkstra function in graphlib

TsCache.prototype.isDirty = function (id, checkImports) {
        var _this = this;
        var label = this.dependencyTree.node(id);
        if (!label)
            return false;
        if (!checkImports || label.dirty)
            return label.dirty;
        if (this.ambientTypesDirty)
            return true;
        var dependencies = alg.dijkstra(this.dependencyTree, id);
        return some(dependencies, function (dependency, node) {
            if (!node || dependency.distance === Infinity)
                return false;
            var l = _this.dependencyTree.node(node);
            var dirty = l === undefined ? true : l.dirty;
            if (dirty)
                _this.context.debug("    import changed: " + node);
            return dirty;
        });
    };
    TsCache.prototype.makeName = function (id, snapshot) {
