### Synopsis

<!-- AUTOGENERATED USAGE DESCRIPTIONS -->

### Description

This command shows data about a package and prints it to stdout.

As an example, to view information about the `connect` package from the registry, you would run:

```bash
npm view connect
```

The default version is `"latest"` if unspecified.

Field names can be specified after the package descriptor.
For example, to show the dependencies of the `ronn` package at version
`0.3.5`, you could do the following:

```bash
npm view ronn@0.3.5 dependencies
```

By default, `npm view` shows data about the current project context (by looking for a `package.json`).
To show field data for the current project use a file path (i.e.
`.`):

```bash
npm view . dependencies
```

You can view child fields by separating them with a period.
To view the git repository URL for the latest version of `npm`, you would run the following command:

```bash
npm view npm repository.url
```

This makes it easy to view information about a dependency with a bit of shell scripting.
For example, to view all the data about the version of `opts` that `ronn` depends on, you could write the following:

```bash
npm view opts@$(npm view ronn dependencies.opts)
```

For fields that are arrays, requesting a non-numeric field will return all of the values from the objects in the list.
For example, to get all the contributor email addresses for the `express` package, you would run:

```bash
npm view express contributors.email
```

You may also use numeric indices in square braces to specifically select an item in an array field.
To just get the email address of the first contributor in the list, you can run:

```bash
npm view express contributors[0].email
```

If the field value you are querying for is a property of an object, you should run:

```bash
npm view express time'[4.8.0]'
```

Note: When accessing object properties that contain special characters or numeric keys, you need to use quotes around the key name.
For example, to get the publish time of a specific version:

```bash
npm view express "time[4.17.1]"
```

Without quotes, the shell may interpret the square brackets as glob patterns, causing the command to fail.
You can also access the time field for a specific version by specifying the version in the package descriptor:

```bash
npm view express@4.17.1 time
```

This will return all version-time pairs, but the context will be for that specific version.

Multiple fields may be specified, and will be printed one after another.
For example, to get all the contributor names and email addresses, you can do this:

```bash
npm view express contributors.name contributors.email
```

"Person" fields are shown as a string if they would be shown as an object.
So, for example, this will show the list of `npm` contributors in the shortened string format.
 (See [`package.json`](/configuring-npm/package-json) for more on this.)

```bash
npm view npm contributors
```

If a version range is provided, then data will be printed for every matching version of the package.
This will show which version of `jsdom` was required by each matching version of `yui3`:

```bash
npm view yui3@'>0.5.4' dependencies.jsdom
```

To show the `connect` package version history, you can do this:

```bash
npm view connect versions
```

### Field Access Patterns

The `npm view` command supports different ways to access nested fields and array elements in package metadata. Understanding these patterns makes it easier to extract specific information.

#### Nested Object Fields

Use dot notation to access nested object fields:

```bash
# Access nested properties
npm view npm repository.url
npm view express bugs.url
```

#### Array Element Access

For arrays, use numeric indices in square brackets to access specific elements:

```bash
# Get the first contributor's email
npm view express contributors[0].email

# Get the second maintainer's name
npm view express maintainers[1].name
```

#### Object Property Access

For object properties (like accessing specific versions in the `time` field), use bracket notation with the property name in quotes:

```bash
# Get publish time for a specific version
npm view express "time[4.17.1]"

# Get dist-tags
npm view express "dist-tags.latest"
```

#### Extracting Fields from Arrays

Request a non-numeric field on an array to get all values from objects in the list:

```bash
# Get all contributor emails
npm view express contributors.email

# Get all contributor names
npm view express contributors.name
```

### Configuration

<!-- AUTOGENERATED CONFIG DESCRIPTIONS -->

### Output

If only a single string field for a single version is output, then it will not be colorized or quoted, to enable piping the output to another command.
If the field is an object, it will be output as a JavaScript object literal.

If the `--json` flag is given, the outputted fields will be JSON.

If the version range matches multiple versions then each printed value will be prefixed with the version it applies to.

If multiple fields are requested, then each of them is prefixed with the field name.
