// require the composer module
const composer = require('@ibm-functions/composer')

// define the composition
const composition = composer.if(
    composer.action('authenticate', { action: function ({ password }) { return { value: password === 'abc123' } } }),
    composer.action('success', { action: function () { return { message: 'success' } } }),
    composer.action('failure', { action: function () { return { message: 'failure' } } }))

// instantiate OpenWhisk client
const wsk = composer.util.openwhisk({ ignore_certs: true })

wsk.compositions.deploy({ name: 'demo', composition }) // deploy composition
    .then(() => wsk.actions.invoke({ name: 'demo', params: { password: 'abc123' }, blocking: true })) // invoke composition
    .then(({ response }) => console.log(JSON.stringify(response.result, null, 4)), console.error)
