How do I manage npm package permissions in a secure domain?

In this guide, we will set up a secure domain for managing npm package permissions using AWS services with Pulumi. We will create an S3 bucket to store npm packages, configure a private npm registry, and set up appropriate permissions to ensure secure access.

Key Points:

S3 Bucket: This will store the npm packages.
IAM Roles and Policies: These will manage access permissions to the S3 bucket.
npm Configuration: We will configure npm to use the private registry hosted on S3.

Steps:

Create an S3 bucket to store npm packages.
Set up IAM roles and policies to manage access to the S3 bucket.
Configure npm to use the S3 bucket as a private registry.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an S3 bucket for storing npm packages
const npmBucket = new aws.s3.Bucket("npmBucket", {
    bucket: "my-secure-npm-registry",
    acl: "private",
    versioning: {
        enabled: true,
    },
    tags: {
        Environment: "Dev",
        Name: "SecureNpmRegistry",
    },
});

// Create an IAM policy for accessing the S3 bucket
const npmBucketPolicy = new aws.iam.Policy("npmBucketPolicy", {
    description: "Policy for accessing the npm S3 bucket",
    policy: npmBucket.bucket.apply(bucketName => JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Effect: "Allow",
                Action: [
                    "s3:GetObject",
                    "s3:PutObject",
                    "s3:ListBucket"
                ],
                Resource: [
                    `arn:aws:s3:::${bucketName}`,
                    `arn:aws:s3:::${bucketName}/*`
                ]
            }
        ]
    })),
});

// Create an IAM role for npm access
const npmAccessRole = new aws.iam.Role("npmAccessRole", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Action: "sts:AssumeRole",
            Effect: "Allow",
            Principal: {
                Service: "ec2.amazonaws.com",
            },
        }],
    }),
});

// Attach the policy to the role
new aws.iam.RolePolicyAttachment("npmAccessRolePolicyAttachment", {
    role: npmAccessRole.name,
    policyArn: npmBucketPolicy.arn,
});

// Export the bucket name and role ARN
export const bucketName = npmBucket.bucket;
export const roleArn = npmAccessRole.arn;

Summary

In this guide, we created an S3 bucket to store npm packages, set up IAM roles and policies to manage access permissions, and configured npm to use the S3 bucket as a private registry. This ensures that npm package permissions are managed securely within a specified domain.
