Advanced tools
A script that helps ensure you have the correct node & npm versions installed in your environment.
A script that helps ensure you have the correct node & npm versions installed globally in your environment.
Add the following to your package.json
:
...
"engines": {
"node": "^10.14.1",
"npm": "^6.4.1"
},
"scripts": {
"preinstall": "npx ensure-node-env",
...
Where the node
and npm
engine properties specify a valid semver range for Node and npm version respectively.
By default, if you have a
node
ornpm
binary installed locally to the project (thus ending up in./node_modules/.bin
), it will take precedence. If you want to check against a globally installed version instead, you can pass the--ignore-local-bin
parameter (-i
for short).It's worth noting that, while you may not be directly depending on
node
ornpm
packages, you may still have them as transitive dependencies - in any case,ensure-node-env
will show which one is being considered and where it comes from.
By default, the script's output is minimal. If you want it to display more information, such as the exact versions being compared, you can pass the --verbose
parameter (-v
for short).
This script is designed to be used as a development-only preinstall check in the project root. For libraries that are published and consumed in other projects it is considered good enough to include it as a pretest check:
npm install ensure-node-env --save-dev
...
"engines": {
"node": "^10.14.1",
"npm": "^6.4.1"
},
"scripts": {
"pretest": "ensure-node-env",
...
Skyscanner Node development requires Node LTS and npm ^16.14.2
. Nvm users can run nvm use
to switch to lts/gallium
. Nave users can use nave auto
. You can also download Node LTS using the website.
