How to use the Bump command line interface.
The Bump CLI is used to interact with your API documentation or hubs hosted on Bump.sh. With any API contract of you choice (from Swagger, OpenAPI v3 or AsyncAPI v2), it can help you to:

## Installing Bump CLI
- Validate an API document before publishing to your documentation
- Publish an API document to your Bump.sh documentation or hubs
- Compare two API documents to generate a human readable diff from your API contracts

Bump CLI is a node package, currently [distributed via NPM](https://www.npmjs.com/package/bump-cli) which means you need to have Node v12+ interpreter installed on your computer and servers.
## Installation

> You can download a standalone package directly from the [latest Github release](https://github.com/bump-sh/cli/releases) assets if you don't use Node. We plan to distribute universal binaries to common package managers soon. Please check our [installation methods](https://github.com/bump-sh/bump-node-cli#installation) for updates.

Unfortunately, at the moment we only support the Node environment. However we plan to distribute universal binaries in the most common package managers very soon. In the meantime, you can download a standalone package directly from the [latest Github release](https://github.com/bump-sh/cli/releases) assets or you can push your documentation using [our API](https://developers.bump.sh/).

## Using Bump CLI
## Usage

To list all the available commands, just type `bump` in your command line environment. You can get some help anytime by using `--help` on any command. Example: `bump deploy --help` .
To list all the available commands, just type `bump` in your command line environment.

## Preview a file
```shell
$ bump --help
The Bump CLI is used to interact with your API documentation hosted on Bump by using the API of developers.bump.sh

When writing a documentation, you'll want to preview how it renders on Bump.sh. This is exactly the goal of the `preview` command: it will create a temporary documentation with a unique URL, which will be available for a short period of time.
VERSION
bump-cli/2.7.2 linux-x64 node-v16.17.0

Usage from a local OpenAPI or AsyncAPI file
USAGE
$ bump [COMMAND]

```shell
bump preview path/to/file.json
COMMANDS
deploy Create a new version of your documentation from the given file or URL.
diff Get a comparison diff with your documentation from the given file or URL.
help Display help for bump.
preview Create a documentation preview from the given file or URL.
```

You can also preview a file available from a URL
You can also get some help anytime by adding `--help` to any command. Example: `bump deploy --help`.

## Prepare your Bump.sh account

While some commands don't need any API token (`preview` or `diff`) you will need an access key if you want to interact with your Bump.sh documentation.

Head to your Documentation Settings in the “CI deployment” section, or your Account or Organization Settings in the “API keys” section to fetch a personnal token for later usage.

## Commands

* [`bump deploy [FILE]`](#bump-deploy-file)
* [`bump diff [FILE]`](#bump-diff-file)
* [`bump preview [FILE]`](#bump-preview-file)

### `bump deploy [FILE]`

When you update your API, you want its documentation to be live for your API users. This is what the deploy command is for. Publish a new API document with this command, and Bump.sh will analyse your API structure and generate a changelog item if the API structure has changed. It will also update your latest published document with the deployed file.

```shell
bump preview https://developers.bump.sh/source.yaml
bump deploy path/to/api-document.yml --doc my-documentation --token $DOC_TOKEN
```

### Live preview

By using the `--live` flag you can stay focused on API design (OpenAPI or AsyncAPI file) while seeing a continuously updated preview each time you save your API definition file.
> You can find your own `my-documentation` slug and `$DOC_TOKEN` api key from your [documentation settings](https://bump.sh/docs).
{: .info}

- Launch the live preview command in your terminal
You can also deploy a given file to a different branch of your documentation with the `--branch <branch-name>` parameter. Please note the branch will be created if it doesn’t exist. More details about the branching feature is available on [this dedicated help page](https://docs.bump.sh/help/branching). E.g. deploy the API document to the `staging` branch of the documentation:

```shell
bump preview --live --open openapi-definition.json
bump deploy path/to/api-document.yml --doc my-documentation --token $DOC_TOKEN --branch staging
```

- Edit your `openapi-definition.json` file in your favorite text editor
- Watch the live preview being updated each time your save your file!
#### Deploy a folder all at once

> You can create as many previews as you like without being authenticated. This is a **free and unlimited service**.
If you already have a hub in your [Bump.sh](https://bump.sh) account, you can automatically create documentation inside it and deploy to it by publishing a whole directory containing multiple API documents in a single command

```shell
bump deploy dir/path/to/apis/ --auto-create --hub my-hub --token $HUB_TOKEN
```

> You can find your own `my-hub` slug and `$HUB_TOKEN` api key from your [hub settings](https://bump.sh/hubs).
{: .info}

## API diff or simple validation before a deployment
Please note, by default, only files named `{slug}-api.[format]` are published. Where `{slug}` is a name for your API and `[format]` is either `yaml` or `json`. Take into account your own file naming convention by using the `--filename-pattern <pattern>` option.

Note that it _can_ include `*` wildcard special character, but **must** include the `{slug}` filter to extract your documentation’s slug from the filename. The pattern can also have any other optional fixed characters.

This is mainly used when you integrate Bump in your automated environments ([Continuous Integration](/help/continuous-integration)). It will validate your documentation file to make sure it is parsed correctly by Bump. If you want to validate your API specification file before a deployment, you can either use:
Here’s a practical example. Suppose you have the following files in your `path/to/apis/` directory:

- [the `bump diff` command](#api-diff-of-your-changes) if you also want to have a human diff summary of your API change
```
path/to/apis
└─ private-api-users-service.json
└─ partner-api-payments-service.yml
└─ public-api-contracts-service.yml
└─ data.json
└─ README.md
```

_or_
In order to deploy the 3 services api definition files from this folder (`private-api-users-service.json`, `partner-api-payments-service.yml` and `public-api-contracts-service.yml`). You can execute the following command:

- [the `bump deploy --dry-run` command](#validation-before-a-deployment) if you only want to make sure the file is valid
```
bump deploy path/to/apis/ --hub my-hub --filename-pattern '*-api-{slug}-service'
```

### API diff of your changes
#### Validate an API document

This command will output a diff summary of what has changed in the API. It can be used to ensure that future file deployment will work smoothly and to get a human diff summary during code reviews.
Simulate a deployment of your API document to make sure it is valid by adding the `--dry-run` flag to the `deploy` command, it is particularly useful in a Continuous Integration environment running a test deployment outside your main branch:

```shell
bump diff path/to/file.json --doc my-documentation
bump deploy path/to/api-document.yml --dry-run --doc my-documentation --token $DOC_TOKEN
```

You can find your own `my-documentation` slug from your [documentation settings](https://bump.sh/docs).
Please check `bump deploy --help` for more usage details.

> You will need to pass your private documentation access token for this command to work. Either with the `--token` flag or via the `BUMP_TOKEN` environment variable. This token can be found from your documentation `settings > CI deployment`page
{: .warning}
### `bump diff [FILE]`

### Validation before a deployment
_If you want to receive automatic `bump diff` results on your Github Pull Requests you might be interested by [our Github Action](https://github.com/marketplace/actions/api-documentation-on-bump#api-diff-on-pull-requests) diff command._

If you don't need a diff summary from the `bump diff` command explained above, you can also make sure your API specification file is valid and parsed correctly by Bump with the `bump deploy --dry-run` command. It can be used to ensure that future file deployment will work smoothly.
#### Public API diffs

From any two API documents or URLs, you can retrieve a comprehensive changelog of what has changed between them.

```shell
bump deploy --dry-run path/to/file.json --doc my-documentation
$ bump diff path/to/your/file.yml path/to/your/second_file.yml
* Comparing the two given definition files... done
Modified: GET /consommations
Response modified: 200
[Breaking] Body attribute modified: energie
```
> You can create as many diffs as you like without being authenticated. This is a **free and unlimited service** provided you have a fair use of the service.
{: .info}

You can find your own `my-documentation` slug from your [documentation settings](https://bump.sh/docs).

> You will need to pass your private documentation access token for this command to work. Either with the `--token` flag or via the `BUMP_TOKEN` environment variable. This token can be found from your documentation `settings > CI deployment`page
{: .warning}
_Note: You can also test this feature in our dedicated web application at <https://api-diff.io/>._

## Deploy a file
#### Authenticated diffs related to your Bump.sh documentation

Once your documentation has been updated and merged, you want it to be live for your API users. This is what the `deploy` command is for. When deploying the new version, Bump will analyse your API structure and will generate a changelog item if the API structure has changed.
From an existing Bump.sh documentation, the `diff` command will retrieve a comparison changelog between your latest published documentation and the given file or URL:

```shell
bump deploy path/to/file.json --doc my-documentation
bump diff path/to/your/file.yml --doc my-documentation --token $DOC_TOKEN
```

You can find your own `my-documentation` slug from your [documentation settings](https://bump.sh/docs).

You can also deploy a given file to a different branch of your documentation with the `--branch <branch-name>` parameter. The branch will be created if it doesn't exist. More details about the branching feature is available on [this dedicated help page](/help/branching).
If you want to compare two unpublished versions of your API document, the `diff` command can retrieve a comparison changelog between two given file or URL, “as simple as `git diff`”:

```shell
bump deploy path/to/file.json --doc my-documentation --branch staging
bump diff path/to/your/file.yml path/to/your/next-file.yml --doc my-documentation --token $DOC_TOKEN
```

> You will need to pass your private documentation access token for this command to work. Either with the `--token` flag or via the `BUMP_TOKEN` environment variable. This token can be found from your documentation `settings > CI deployment`page.
{: .warning}
Please check `bump diff --help` for full usage details.

### `bump preview [FILE]`


## Deploy a folder
When writing a documentation, you might want to preview how it renders on Bump.sh. This is exactly the goal of the `preview` command: it will create a temporary documentation with a unique URL, which will be available for a short period of time.

When using the [Hub](/help/hubs) feature on Bump.sh, you might want to deploy multiple api definition files in a single command. The `deploy` command described in the [previous paragraph](#deploy-a-file) accepts a folder path as argument to do just that:
Usage from a local OpenAPI or AsyncAPI file

```shell
bump deploy path/to/apis/ --hub my-hub
bump preview path/to/file.json
```

> You can find your own `my-hub` slug from your [hub settings](https://bump.sh/hubs).
{: .info}
You can also preview a file available from a URL

Take into account your file naming convention by using the `--filename-pattern <pattern>` option.
```shell
bump preview https://developers.bump.sh/source.yaml
```

Note that it can include `*` wildcard special character, `{slug}` filter that will extract your documentation's slug from the filename, as well as any other fixed characters.
#### Live preview

Here's a practical example. Suppose you have the following files in your `path/to/apis/` directory:
By using the `--live` flag you can stay focused on API design (OpenAPI or AsyncAPI file) while seeing a continuously updated preview each time you save your API document.

- Launch the live preview command in your terminal

```shell
path/to/apis
└─ private-api-users-service.json
└─ partner-api-payments-service.yml
└─ public-api-contracts-service.yml
└─ data.json
└─ README.md
bump preview --live --open openapi-definition.json
```

In order to deploy the 3 services api definition files from this folder (`private-api-users-service.json`, `partner-api-payments-service.yml` and `public-api-contracts-service.yml`). You can execute the following command:
- Edit your `openapi-definition.json` file in your favorite text editor
- Watch the live preview being updated each time your save your file!

```shell
bump deploy path/to/apis/ --hub my-hub --filename-pattern *-api-{slug}-service
```
> You will need to pass your private hub access token for this command to work. Either with the `--token` flag or via the `BUMP_TOKEN` environment variable. This token can be found from your hub `settings > CI deployment` page.
{: .warning}
> You can create as many previews as you like without being authenticated. This is a **free and unlimited service**.
{: .info}

_Note: the additional `--open` flag helps to automatically open the preview URL in your browser._

Please check `bump preview --help` for more usage details
