[`libnpmteam`](https://github.com/npm/libnpmteam) is a Node.js
library that provides programmatic access to the guts of the npm CLI's `npm
team` command and its various subcommands.
## Example
```javascript
const access = require('libnpmteam')
// List all teams for the @npm org.
console.log(await team.lsTeams('npm'))
```

### API
#### `opts` for `libnpmteam` commands
`libnpmteam` uses [`npm-registry-fetch`](https://npm.im/npm-registry-fetch).
All options are passed through directly to that library, so please refer to [its
own `opts`
documentation](https://www.npmjs.com/package/npm-registry-fetch#fetch-options)
for options that can be passed in.
A couple of options of note for those in a hurry:
* `opts.token` - can be passed in and will be used as the authentication token for the registry. For other ways to pass in auth details, see the n-r-f docs.
* `opts.otp` - certain operations will require an OTP token to be passed in. If a `libnpmteam` command fails with `err.code === EOTP`, please retry the request with `{otp: <2fa token>}`
* `opts.Promise` - If you pass this in, the Promises returned by `libnpmteam` commands will use this Promise class instead. For example: `{Promise: require('bluebird')}`
#### `> team.create(team, [opts]) -> Promise`
Creates a team named `team`. Team names use the format `@:`, with
the `@` being optional.
Additionally, `opts.description` may be passed in to include a description.
##### Example
```javascript
await team.create('@npm:cli', {token: 'myregistrytoken'})
// The @npm:cli team now exists.
```
#### `> team.destroy(team, [opts]) -> Promise`
Destroys a team named `team`. Team names use the format `@:`, with
the `@` being optional.
##### Example
```javascript
await team.destroy('@npm:cli', {token: 'myregistrytoken'})
// The @npm:cli team has been destroyed.
```
#### `> team.add(user, team, [opts]) -> Promise`
Adds `user` to `team`.
##### Example
```javascript
await team.add('zkat', '@npm:cli', {token: 'myregistrytoken'})
// @zkat now belongs to the @npm:cli team.
```
#### `> team.rm(user, team, [opts]) -> Promise`
Removes `user` from `team`.
##### Example
```javascript
await team.rm('zkat', '@npm:cli', {token: 'myregistrytoken'})
// @zkat is no longer part of the @npm:cli team.
```
#### `> team.lsTeams(scope, [opts]) -> Promise`
Resolves to an array of team names belonging to `scope`.
##### Example
```javascript
await team.lsTeams('@npm', {token: 'myregistrytoken'})
=>
[
'npm:cli',
'npm:web',
'npm:registry',
'npm:developers'
]
```
#### `> team.lsTeams.stream(scope, [opts]) -> Stream`
Returns a stream of teams belonging to `scope`.
For a Promise-based version of these results, see [`team.lsTeams()`](#ls-teams).
##### Example
```javascript
for await (let team of team.lsTeams.stream('@npm', {token: 'myregistrytoken'})) {
console.log(team)
}
// outputs
// npm:cli
// npm:web
// npm:registry
// npm:developers
```
#### `> team.lsUsers(team, [opts]) -> Promise`
Resolves to an array of usernames belonging to `team`.
For a streamed version of these results, see [`team.lsUsers.stream()`](#ls-users-stream).
##### Example
```javascript
await team.lsUsers('@npm:cli', {token: 'myregistrytoken'})
=>
[
'iarna',
'zkat'
]
```
#### `> team.lsUsers.stream(team, [opts]) -> Stream`
Returns a stream of usernames belonging to `team`.
For a Promise-based version of these results, see [`team.lsUsers()`](#ls-users).
##### Example
```javascript
for await (let user of team.lsUsers.stream('@npm:cli', {token: 'myregistrytoken'})) {
console.log(user)
}
// outputs
// iarna
// zkat
```
