| # How to Check Your Mongoose Version | ||
|
|
||
| To check what version of Mongoose you are using in Node.js, print out the [`mongoose.version` property](./api/mongoose.html#Mongoose.prototype.version) as follows. | ||
|
|
||
| ```javascript | ||
| const mongoose = require('mongoose'); | ||
|
|
||
| console.log(mongoose.version); // '7.x.x' | ||
| ``` | ||
|
|
||
| We recommend printing the Mongoose version from Node.js, because that better handles cases where you have multiple versions of Mongoose installed. | ||
| You can also execute the above logic from your terminal using Node.js' `-e` flag as follows. | ||
|
|
||
| ``` | ||
| # Prints current Mongoose version, e.g. 7.0.3 | ||
| node -e "console.log(require('mongoose').version)" | ||
| ``` | ||
|
|
||
| ## Using `npm list` | ||
|
|
||
| You can also [get the installed version of the Mongoose npm package](https://masteringjs.io/tutorials/npm/version) using `npm list`. | ||
|
|
||
| ``` | ||
| $ npm list mongoose | ||
| test@ /path/to/test | ||
| └── mongoose@7.0.3 | ||
| ``` | ||
|
|
||
| `npm list` is helpful because it can identify if you have multiple versions of Mongoose installed. | ||
|
|
||
| Other package managers also support similar functions: | ||
|
|
||
| - [`yarn list --pattern "mongoose"`](https://classic.yarnpkg.com/lang/en/docs/cli/list/) | ||
| - [`pnpm list "mongoose"`](https://pnpm.io/cli/list) |
