25. unit & module guidelines ▪short units of code – up to 15 lines ▪simple units of code – up to 4 branch points ▪write code once ▪small unit interface ▪separate concerns in modules – small modules refactoring techniques extract method extract object unit: method, function module: file, class, function

26. module guidelines ▪loosely coupled components – small module interface ▪balanced number & size of top level components ▪small codebase

27. technology & tools ▪ TypeScript ▪ npm, bower, gulp, tsd, … ▪ internal package repository (Nexus) ▪ build automation (TFS) ▪ maintainability tools (SonarLint) ▪ maintainability monitoring (SIG, SonarQube)
