conventionaljs

Conventional tests for your JS and TS.

There is only one rule so far and it's incomplete.

• Make sure AWS Lambda event handler input parameters don't escape the file they are defined in.

Usage

You'll need entente or ts-morph for this.

entente (known entrypoints only at the moment)

const { createProject } = require("ts-morph");
createProject('./src/index.js');

checkProject(project) 

ts-morph (find entrypoints in a source tree)

const compilerOptions = {
  allowJs: true,
  checkJs: true,
  noEmit: true,
  resolveJsonModule: true,
};

const project = new Project({ compilerOptions });
project.resolveSourceFileDependencies();
project.addSourceFilesAtPaths(['./src/**/*.js', "!./src/**/*.spec.js"]);

checkProject(project) 

Todos

• [ ] Make it work with commonjs modules. ts-morph is having a hard time here.
• [ ] Make it work when someone hasn't annotated the function with JSDoc. There are few things we can do here around scoring the function based on name handler and whether it has 3 params (event, context, callback) or 1-2 params (event, [context]) for async functions.
• [ ] Make sure it doesn't escape through a renamed reference.
