How to know what you can import from package?-CodePudding

Let's say there is no intellisense for node packages in Visual studio code(Sometimes intellisense doesn't work properly for a package it can't intellisense some field in the package), how do you know what you can import ?

CodePudding user response：

You can search directly in the source code (in the node_modules folder there is a folder called as the package, find module.exports or export keywords) or check the documentation if there is one.

CodePudding user response：

You could get every key of the imported variable

const fs = require('fs');
console.log(Object.keys(module))
// ["writeFile","readdir","readdirSync",...]

Unless what's imported is a class for example when you'd have to get it's .prototype value. This will give you every function and property listed in the module exported object
