# Please upgrade Node [](https://www.npmjs.org/package/please-upgrade-node) [](https://travis-ci.org/typicode/please-upgrade-node) [](https://www.npmjs.com/package/please-upgrade-node)

> :information_desk_person: show a message to your users to upgrade Node instead of a stacktrace
|
||
|
|
|
||
|
|
It's common for new Node users to miss or not understand engines warning when installing a CLI. This package displays a beginner-friendly message if their Node version is below the one expected.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ node -v
|
||
|
|
0.12
|
||
|
|
|
||
|
|
$ modern-cli
|
||
|
|
modern-cli requires at least version 6 of Node, please upgrade
|
||
|
|
```
|
||
|
|
|
||
|

|
## Usage
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install please-upgrade-node
|
||
|
|
```
|
||
|
|
|
||
|
|
Add `please-upgrade-node` at the top of your CLI
|
||
|
|
|
||
|
|
```js
|
||
|
|
#!/usr/bin/env node
|
||
|
|
const pkg = require('./package.json')
|
||
|
|
require('please-upgrade-node')(pkg) // <- Must run BEFORE requiring any other modules
|
||
|
|
|
||
|
|
// ...
|
||
|
|
```
|
||
|
|
|
||
|
|
Set in your `package.json` the required Node version
|
||
|
|
|
||
|
|
```js
|
||
|
|
{
|
||
|
|
"engines": {
|
||
|
|
"node": ">=6"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
__Important__: `>=` is the only operator supported by `please-upgrade-node` (e.g. `>=6`, `>=6.0`, `>=6.0.0`).
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
You can set custom `exitCode` and `message` function if needed
|
||
|
|
|
||
|
|
```js
|
||
|
|
pleaseUpgradeNode(pkg, {
|
||
|
|
exitCode: 0, // Default: 1
|
||
|
|
message: function(requiredVersion) {
|
||
|
|
return 'Oops this program require Node ' + requiredVersion
|
||
|
|
}
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
__Important__: to keep `message` function compatible with older versions of Node, avoid using ES6 features like `=>` or string interpolation.
