## Install

Requires [Node](https://nodejs.org/en/) version 6 or above.

```sh
npm install --save @cypress/deploy-bits
```

## Use

### Debugging

To debug functions from this module, run the program with `DEBUG=deploy-bits` environment
variable.

### isCI

Returns `true` if the code is running on a common continuous integration server.
Uses [is-ci](https://github.com/watson/is-ci).

```js
const {isCI} = require('@cypress/deploy-bits')
if (isCI) {
// we are on CI
}
```

### warnIfNotCI

Prints a console warning if the code is not running on CI. Often we prefer deploying
from CI rather than running the deploy command locally.

```js
const {warnIfNotCI} = require('@cypress/deploy-bits')
warnIfNotCI()
```

### getDeployEnvironment

Returns target deployment environment `staging` or `production`

```js
const {getDeployEnvironment} = require('@cypress/deploy-bits')
getDeployEnvironment()
.then(env => ...)
```

If the user specified environment using CLI `--environment ` option, it will be used.
Otherwise, user will be prompted to select one.

```
? Which environment are you deploying?
❯ Staging
Production
```

You can pass list of arguments for this function to parse (by default it uses `process.argv`)
```js
getDeployEnvironment(['--environment', 'staging']) // yields "staging"
```
and you can even pass [minimist](https://github.com/substack/minimist) parsing options
```js
const options = {
alias: {
environment: 'e'
}
}
getDeployEnvironment(['-e', 'staging']) // yields "staging"
```

### getBranch

Resolves with current branch.

```js
const {getBranch} = require('@cypress/deploy-bits')
getBranch()
.then(branch => ...)
```

### checkBranchEnvFolder

Checks the branch to environment mapping. For some branches checks if the working
directory is clean (no modified source files). Always returns input environment name.
Curried.

```js
const {checkBranchEnvFolder} = require('@cypress/deploy-bits')
// synchronous method
checkBranchEnvFolder('master')('production')
// returns "production"
// will throw an error if there are modified files
```

### getS3Config

Returns S3 config loaded from environment variable or local file. If cannot find either,
throws an error.

```js
const {getS3Config} = require('@cypress/deploy-bits')
const config = getS3Config()
```

Typical config file in `support/.aws-credentials.json` contains

```json
{
"bucket-production": "",
"bucket-staging": "",
"key": "AWS API key",
"secret": "AWS API secret"
}
```

### getS3Publisher

Returns an instance of [gulp-awspublish](https://github.com/pgherveou/gulp-awspublish)

```js
const {getS3Config, getS3Publisher} = require('@cypress/deploy-bits')
const config = getS3Config()
const publisher = getS3Publisher(config['bucket-production'], config.key, config.secret)
```

### publishToS3

Uploads (diffs) a local folder to AWS S3 folder.

```js
const {getS3Config, getS3Publisher, publishToS3} = require('@cypress/deploy-bits')
const config = getS3Config()
const publisher = getS3Publisher(config['bucket-production'], config.key, config.secret)
publishToS3('dist/public', publisher)
// returns a promise
```

Note: if a local folder contains `build.json` it will be uploaded with "no cache" headers.

### uploadToS3

Normal local folder upload to S3 using above functions.

```js
const {uploadToS3} = require('@cypress/deploy-bits')
uploadToS3('dist/public', 'production')
.then(...)
```
