1. Installed jspdf in package.json, "jspdf": "^2.1.0" 2. When compiling my project with typescript, I get the following error: ``` [app-scripts] typescript: .../App/node_modules/jspdf/types/index.d.ts, line: 1334 [app-scripts] A tuple type element list cannot be empty. ``` 3. Can be fixed by adding "any" before the "[]" type at this position ``` export interface jsPDFAPI { events: any[]; // any[] instead of just [] } ```
