TypeScript Compile Options: module vs target

There are 2 different things. --target simply means which version of ECMAScript you're using to code. --module simply means which module system you're using such as commonjs for Node or ES module for all that supports it and what not.

A more detailed explanation is here : Understanding "target" and "module" in tsconfig

See also: Understanding "target" and "module" in tsconfig.

Here is a quote from the documentation on compiler options:

--target

Specify ECMAScript target version: 'es3' (default), 'es5', or 'es6'.

--module

Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es6', or 'es2015'.

• Only 'amd' and 'system' can be used in conjunction with --outFile.
• 'es6' and 'es2015' values may be used when targeting ES5 or lower.

The "target" property is used to specify the JavaScript version your TypeScript code will eventually compile into. The "module" property specifies the type of the module syntax your compiled (TS-->JS) code will use. For instance if you set the module property to "commonJS", your compiled code will use "require/module.exports" to import/export. The module property will not however affect the rest of the compiled code. For the sake of clarity, please refer this answer: https://stackoverflow.com/a/61215252/8659116
