Nodejs implementation of #18133 DependsOn for resources is an ordering constraint for register resource calls. If a resource R1 depends on a resource R2, the register resource call for R2 will happen after R1. This is ensured by awaiting the URN for each resource dependency before calling register resource. For invokes, this causes a problem when running under preview. During preview, register resource immediately returns with the URN, however this does not tell us if the resource "exists". Instead of waiting for the dependency's URN, we wait for the ID. This tells us that whether a physical resource exists (if the state is in sync), and we can avoid calling the invoke when it is unknown. The following example fails without this change: ```typescript import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; const config = new pulumi.Config() const billingAccountId = config.require("billing-account") const billingAccount = gcp.organizations.getBillingAccountOutput({ billingAccount: billingAccountId }) const project = new gcp.organizations.Project("project", { billingAccount: billingAccount.id, name: "project-nodejs", autoCreateNetwork: false, deletionPolicy: "DELETE", }) export const zones = gcp.compute.getZonesOutput({ project: project.projectId, region: "us-central1" }, { dependsOn: [project], }) ``` |

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. Visit Pulumi's Download & Install to install the CLI.
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 any of the Current, Active and Maintenance LTS versions. 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
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 $HOME/.dev-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.
