node/prefer-global/process

enforce either process or require("process")

The process module is defined as a global variable.

process.log(process === require("process")) //→ true

It will be readable if we use either process consistently.

📖 Rule Details

This rule enforces which process we should use.

Options

This rule has a string option.

{
    "node/prefer-global/process": ["error", "always" | "never"]
}
  • "always" (default) ... enforces to use the global variable process rather than require("process").
  • "never" ... enforces to use require("process") rather than the global variable process.

always

/*eslint node/prefer-global/process: [error]*/

const process = require("process")

/*eslint node/prefer-global/process: [error]*/

process.exit(0)
