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.

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.

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

getDeployEnvironment

Returns target deployment environment staging or production

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

If the user specified environment using CLI --environment <name> 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)

getDeployEnvironment(['--environment', 'staging']) // yields "staging"

and you can even pass minimist parsing options

const options = {
  alias: {
    environment: 'e'
  }
}
getDeployEnvironment(['-e', 'staging']) // yields "staging"

getBranch

Resolves with current branch.

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.

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.

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

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

{
  "bucket-production": "<production S3 folder name>",
  "bucket-staging": "<staging S3 folder name>",
  "key": "AWS API key",
  "secret": "AWS API secret"
}

getS3Publisher

Returns an instance of gulp-awspublish

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.

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.

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