### CLI Usage

Crosspost also has a command line interface to allow for incorporation into CI systems.

```
Usage: crosspost [options] "Message to post."
--twitter, -t Post to Twitter.
--mastodon, -m Post to Mastodon.
--bluesky, -b Post to Bluesky.
--help, -h Show this message.
```

Example:

```
npx crosspost -t -m -b "Hello world!"
# or
npx @humanwhocodes/crosspost -t -m -b "Hello world!"
```

This posts the message `"Hello world!"` to Twitter, Mastodon, and Bluesky. You can choose to post to any combination by specifying the appropriate command line options.

Each strategy requires a set of environment variables in order to execute:

- Twitter
- `TWITTER_ACCESS_TOKEN_KEY`
- `TWITTER_ACCESS_TOKEN_SECRET`
- `TWITTER_API_CONSUMER_KEY`
- `TWITTER_API_CONSUMER_SECRET`
- Mastodon
- `MASTODON_ACCESS_TOKEN`
- `MASTODON_HOST`
- Bluesky
- `BLUESKY_HOST`
- `BLUESKY_IDENTIFIER`
- `BLUESKY_PASSWORD`

Tip: You can also load environment variables from a `.env` file in the current working directory by setting the environment variable `CROSSPOST_DOTENV` to `1`.

## Setting up Strategies

Each strategy uses the service's preferred way of posting messages, so you'll need to follow specific steps in order to enable API access.
