I already had a library that I wanted to convert to Typescript. I picked Rollup.js to do my build process. First I installed the following packages: > npm i -E -D rollup typescript @rollup/plugin-commonjs\ @rollup/plugin-node-resolve rollup-plugin-typescript2\ rollup-plugin-peer-deps-external I ended up with: * [email protected] * [email protected] * [email protected] * [email protected] * @rollup/[email protected] * @rollup/[email protected] Then I created a tsconfig.json: { "compilerOptions": { "outDir": "build", "module": "esnext", "target": "es5", "lib": ["es6", "dom", "es2016", "es2017"], "sourceMap": true, "allowJs": false, "declaration": true, "moduleResolution": "node", "forceConsistentCasingInFileNames": true, "noImplicitReturns": true, "noImplicitThis": true, "noImplicitAny": true, "strictNullChecks": true, "suppressImplicitAnyIndexErrors": true, "noUnusedLocals": true, "noUnusedParameters": true, "esModuleInterop": true, "allowSyntheticDefaultImports": true }, "include": ["src"], "exclude": ["node_modules", "build"] } Also a rollup.config.js: ...

Resilience means the capacity to recover quickly from difficulties. Circuit breaker pattern is a good practice for resilience. When working with distributed systems, you want resilience. If you’re working with “micro-services,” you probably have faced with the problem of a service going down. When X service goes down, and Y and Z depend on X, every internal exception could potentially start taking other services down. If you don’t work with micro-services, you might still have an integration with a payment provider (PayPal, Stripe, Google Play, etc.). What happens when any of those providers goes down? Imagine a request comes to your internal service, then your service makes a request to Stripe, then Stripe takes 30 seconds to tell you there was something wrong. How many requests have queued up in 30 seconds in your service? ...
