Auth & Registry Settings (.npmrc)

The settings on this page must be configured via .npmrc files. pnpm uses the npm CLI under the hood for publishing, so these settings need to be in a format that npm can read.

For details on how .npmrc files are loaded, see the pnpm config command.

For settings that can be configured in pnpm-workspace.yaml, see Settings (pnpm-workspace.yaml).

Variables de entorno

Values in .npmrc files may reference environment variables using the ${NAME} syntax.

Since v10.34.2, environment variables are not expanded in the project and workspace .npmrc files (those checked out together with the repository) for the following settings:

registry and proxy URLs (registry, @scope:registry, proxy, https-proxy, http-proxy);
URL-scoped keys (keys starting with //);
credential values (_authToken, _auth, _password, username, tokenHelper, cert, key).

A setting that contains a ${...} placeholder in any of these positions is ignored, and pnpm prints a warning. Repository-controlled .npmrc files must not be able to expand environment variables into the URLs pnpm sends requests to, or into the credentials attached to those requests — otherwise a malicious repository could exfiltrate secrets from your environment (such as CI tokens) to an attacker-controlled registry during installation (GHSA-3qhv-2rgh-x77r).

If your project relied on a committed .npmrc containing a line like //registry.npmjs.org/:_authToken=${NPM_TOKEN}, move the token to a trusted location instead:

Write the token to the global config file before installing (for example, in a CI step):
```
pnpm config set //registry.npmjs.org/:_authToken "$NPM_TOKEN"
```
pnpm config set writes to the global config file by default, not to the project .npmrc, so the token never ends up in the repository.
Or keep the ${NPM_TOKEN} placeholder line, but put it in the user-level ~/.npmrc instead of the repository — environment variables are still expanded there.

Or set the value via an environment variable directly, without any .npmrc entry:

npm_config_//registry.npmjs.org/:_authToken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

In GitHub Actions, actions/setup-node with the registry-url input writes the auth setting to a user-level .npmrc (referenced by the NPM_CONFIG_USERCONFIG environment variable, which pnpm honors), so authentication via the NODE_AUTH_TOKEN environment variable continues to work.
If you cannot easily modify each CI pipeline, you may declare the project .npmrc trusted by setting a single environment variable in the CI environment (for example, at the organization or workspace level):
```
NPM_CONFIG_USERCONFIG=.npmrc
```
This makes pnpm read the project's .npmrc as the user-level config file (a relative path is resolved against the working directory), so environment variables in it are expanded as before. Because the trust declaration comes from the environment — not from the repository — a malicious repository cannot set it for you.

danger
Only use this in environments that exclusively build trusted repositories. It disables this protection entirely for the checked-out repository, including the restriction that tokenHelper may only be set in user-level config.

The same rule applies to registry and proxy URLs in a project or workspace .npmrc (registry, @scope:registry, proxy, https-proxy, http-proxy). If you used an environment variable to build a registry URL, move the setting to a trusted source — your user-level ~/.npmrc, the global config (pnpm config set "<key>" <value>), a CLI option, or an environment variable. If the URL is not secret, you can also write the resolved value directly in the project .npmrc, since only ${...} placeholders are ignored.

Registry Settings

registry

Default: https://registry.npmjs.org/
Type: url

The base URL of the npm package registry (trailing slash included).

@jsr:registry

Added in: v10.9.0

Default: https://npm.jsr.io/
Type: url

The base URL of the JSR package registry.

<scope>:registry

The npm registry that should be used for packages of the specified scope. For example, setting @babel:registry=https://example.com/packages/npm/ will enforce that when you use pnpm add @babel/core, or any @babel scoped package, the package will be fetched from https://example.com/packages/npm instead of the default registry.

Authentication Settings

<URL>:_authToken

Defina la señal de portadora de autenticación que se debe utilizar al acceder al registro especificado. Por ejemplo:

//registry.npmjs.org/:_authToken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

También puede utilizar una variable de entorno. Por ejemplo:

//registry.npmjs.org/:_authToken=${NPM_TOKEN}

Since v10.34.2, environment variables are only expanded in trusted locations (the user ~/.npmrc, the global config, CLI options, and npm_config_* environment variables), not in the project or workspace .npmrc. See Environment variables.

Or you may just use an environment variable directly, without changing .npmrc at all:

npm_config_//registry.npmjs.org/:_authToken=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

<URL>:tokenHelper

Un token de ayuda es un ejecutable que genera un token de autenticación. Esto se puede usar en situaciones en las que authToken no es un valor constante sino algo que se actualiza regularmente, donde un script u otra herramienta puede usar un token de actualización existente para obtener un nuevo token de acceso.

La configuración de la ruta al asistente debe ser una ruta absoluta, sin argumentos. In order to be secure, it is only permitted to set this value in the user .npmrc. Otherwise a project could place a value in a project's local .npmrc and run arbitrary executables.

Proxy Settings

https-proxy

Default: null
Type: url

Un proxy para usar con solicitudes HTTPS salientes. If the HTTPS_PROXY, https_proxy, HTTP_PROXY or http_proxy environment variables are set, their values will be used instead.

If your proxy URL contains a username and password, make sure to URL-encode them. Por ejemplo:

https-proxy=https://use%21r:pas%2As@my.proxy:1234/foo

Do not encode the colon (:) between the username and password.

http-proxy

proxy

Default: null
Type: url

Un proxy para usar con solicitudes http salientes. Si se establecen las variables de entorno HTTP_PROXY o http_proxy, la biblioteca de solicitud subyacente respetará la configuración del proxy.

local-address

Default: undefined
Type: IP Address

La dirección IP de la interfaz local que se usará al realizar conexiones con el registro npm.

maxsockets

Default: networkConcurrency x 3
Type: Number

El número máximo de conexiones a usar por origen (combinación de protocolo/host/puerto).

noproxy

Default: null
Type: String

Una cadena de extensiones de dominio separadas por comas para las que no se debe usar un proxy.

SSL Settings

strict-ssl

Default: true
Type: Boolean

Si realizar o no la validación de la clave SSL al realizar solicitudes al registro a través de HTTPS.

Certificate Settings

ca

Default: The npm CA certificate
Type: String, Array or null

El certificado de firma de la autoridad de certificación en el que se confía para las conexiones SSL con el registro. Los valores deben estar en formato PEM (también conocido como "X.509 codificado en Base-64 (.CER)"). Por ejemplo:

ca="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

Se establece en nulo para permitir sólo a los registradores conocidos, o a un certificado de CA específico para confiar en sólo la autorización de firma específica.

Se puede confiar en varias CA especificando una arreglo de certificados:

ca[]="..."
ca[]="..."

cafile

Default: null
Type: path

Una ruta a un archivo que contiene uno o varios certificados de firma de autoridad de certificación. Similar to the ca setting, but allows for multiple CAs, as well as for the CA information to be stored in a file instead of being specified via CLI.

<URL>:cafile

Define the path to a Certificate Authority file to use when accessing the specified registry. Por ejemplo:

//registry.npmjs.org/:cafile=ca-cert.pem

<URL>:ca

Added in: v10.25.0

Define an inline Certificate Authority certificate for the specified registry. The value must be PEM-encoded, like the global ca setting, but it only applies to the matching registry URL.

//registry.example.com/:ca=-----BEGIN CERTIFICATE-----...-----END CERTIFICATE-----

cert

Default: null
Type: String

Un certificado de cliente para pasar al acceder al registro. Los valores deben estar en formato PEM (también conocido como "X.509 codificado en Base-64 (.CER)"). Por ejemplo:

cert="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

It is not the path to a certificate file.

<URL>:cert

Added in: v10.25.0

Define an inline client certificate to use when accessing the specified registry. Ejemplo:

//registry.example.com/:cert=-----BEGIN CERTIFICATE-----...-----END CERTIFICATE-----

<URL>:certfile

Define the path to a certificate file to use when accessing the specified registry. Por ejemplo:

//registry.npmjs.org/:certfile=server-cert.pem

key

Default: null
Type: String

Una clave de cliente para pasar al acceder al registro. Los valores deben estar en formato PEM (también conocido como "X.509 codificado en Base-64 (.CER)"). Por ejemplo:

key="-----BEGIN PRIVATE KEY-----\nXXXX\nXXXX\n-----END PRIVATE KEY-----"

It is not the path to a key file. Use <URL>:keyfile if you need to reference the file system instead of inlining the key.

Esta configuración contiene información confidencial. Don't write it to a local .npmrc file committed to the repository.

<URL>:key

Added in: v10.25.0

Define an inline client key for the specified registry URL.

//registry.example.com/:key=-----BEGIN PRIVATE KEY-----...-----END PRIVATE KEY-----

<URL>:keyfile

Define the path to a client key file to use when accessing the specified registry. Por ejemplo:

//registry.npmjs.org/:keyfile=server-key.pem
