These changes add support for provider-side previews of create and update operations, which allows resource providers to supply output property values for resources that are being created or updated during a preview. If a plugin supports provider-side preview, its create/update methods will be invoked during previews with the `preview` property set to true. It is the responsibility of the provider to fill in any output properties that are known before returning. It is a best practice for providers to only fill in property values that are guaranteed to be identical if the preview were instead an update (i.e. only those output properties whose values can be conclusively determined without actually performing the create/update operation should be populated). Providers that support previews must accept unknown values in their create and update methods. If a plugin does not support provider-side preview, the inputs to a create or update operation will be propagated to the outputs as they are today. Fixes #4992. |

Pulumi Node.js SDK
The Pulumi Node.js SDK lets you write cloud programs in JavaScript.
Installation
Using npm:
$ npm install --save @pulumi/pulumi
Using yarn:
$ yarn add @pulumi/pulumi
This SDK is meant for use with the Pulumi CLI. Please visit pulumi.com for installation instructions.
Building and Testing
For anybody who wants to build from source, here is how you do it.
Prerequisites
This SDK uses Node.js and we support the Active LTS and Current releases, as defined by this table. We support both NPM and Yarn for package management.
At the moment, we only support building on macOS and Linux, where standard GNU tools like make are available.
Make Targets
The first time you build, run make ensure to install and prepare native plugins for V8:
$ make ensure
This is only necessary if you intend to produce a build that is capable of running older versions of the SDK
contained in this directory. If you do intend to do this, you must have node 6.10.2 installed.
To build the SDK, simply run make from the root directory (where this README lives, at sdk/nodejs/ from the repo's
root). This will build the code, run tests, and install the package and its supporting artifacts.
At the moment, for local development, we install everything into /opt/pulumi. You will want this on your $PATH.
The tests will verify that everything works, but feel free to try running pulumi preview and/or pulumi up from
the examples/minimal/ directory. Remember to run tsc first, since pulumi expects JavaScript, not TypeScript.
