# Installing NPM Packages Behind Proxy
|
|
|
|
On a recent assignment, I needed to install npm behind a corporate proxy. I had already set the environment variables `HTTP_PROXY` and `HTTPS_PROXY`. Other command line utilities, like ruby gems, recognized these environment variables. Npm did not.
|
|
|
|
After some googling, I found the following way to configure the proxy for npm.
|
|
|
|
```bash
|
|
# npm
|
|
npm config set proxy <http://127.0.0.1:7890>
|
|
npm config set https-proxy <http://127.0.0.1:7890>
|
|
|
|
# yarn
|
|
yarn config set proxy <http://127.0.0.1:7890>
|
|
yarn config set https-proxy <http://127.0.0.1:7890>
|
|
```
|
|
|
|
If you need to specify credentials, they can be passed in the url using the following syntax.
|
|
|
|
```
|
|
[<http://user_name:password@proxy.company.com:8080>](<http://user_name:password@proxy.company.com:8080/>)
|
|
```
|
|
|
|
Further exploration of the [npm config documentation](https://npmjs.org/doc/config.html) showed that the `npm config set` command sets the proxy configuration in your `.npmrc` file. You can also set the proxy configuration as a command line argument or environment variable.
|
|
|
|
Configuration parameters can be specified using `--` when executing npm. So the proxy could also be specified as follows.
|
|
|
|
```bash
|
|
npm --https-proxy=http://proxy.company.com:8080 -g install karma
|
|
```
|
|
|
|
To pass configurattion parameters to npm as environment variables, they must be prefixed with `npm_config_`. The proxy configuration could be set with environment variables as follows.
|
|
|
|
```bash
|
|
export npm_config_proxy <http://proxy.company.com:8080>
|
|
export npm_config_https_proxy <http://proxy.company.com:8080>
|
|
``` |
