| + | ==== Best way to swap node versions ==== | ||
| + | |||
| + | The continuous exchange of NodeJS environments in your machine can bring some issues or be too uncomfortable. The best way to manage this is the ''nvm'' tool. | ||
| + | |||
| + | * https://github.com/nvm-sh/nvm | ||
| + | |||
| + | There you will find the installation procedure to follow. Once you have it, the use is as it follows: | ||
| + | |||
| + | <code> | ||
| + | $ nvm use 16 | ||
| + | Now using node v16.9.1 (npm v7.21.1) | ||
| + | $ node -v | ||
| + | v16.9.1 | ||
| + | $ nvm use 14 | ||
| + | Now using node v14.18.0 (npm v6.14.15) | ||
| + | $ node -v | ||
| + | v14.18.0 | ||
| + | $ nvm install 12 | ||
| + | Now using node v12.22.6 (npm v6.14.5) | ||
| + | $ node -v | ||
| + | v12.22.6 | ||
| + | </code> | ||
