RegexPatternSet

Learn how to create, update, and manage AWS WAFv2 RegexPatternSets using Alchemy Cloud Control.

The RegexPatternSet resource allows you to manage AWS WAFv2 RegexPatternSets that contain regular expressions for filtering web requests.

Minimal Example

Create a basic RegexPatternSet with required properties and a description.

import AWS from "alchemy/aws/control";

const regexPatternSet = await AWS.WAFv2.RegexPatternSet("myRegexPatternSet", {
  Scope: "REGIONAL",
  RegularExpressionList: [
    "^(example\\.)?mywebsite\\.com$"
  ],
  Description: "A set of regex patterns for my website"
});

Advanced Configuration

Configure a RegexPatternSet with tags and an optional name.

const advancedRegexPatternSet = await AWS.WAFv2.RegexPatternSet("advancedRegexPatternSet", {
  Scope: "CLOUDFRONT",
  RegularExpressionList: [
    "^.*\\.example\\.com$",
    "^.*mywebsite\\.com$"
  ],
  Name: "MyAdvancedRegexPatternSet",
  Tags: [
    { Key: "Environment", Value: "Production" },
    { Key: "Project", Value: "WebSecurity" }
  ]
});

Adoption of Existing Resource

Adopt an existing RegexPatternSet instead of failing if it already exists.

const adoptedRegexPatternSet = await AWS.WAFv2.RegexPatternSet("adoptedRegexPatternSet", {
  Scope: "REGIONAL",
  RegularExpressionList: [
    "^secure\\.mywebsite\\.com$"
  ],
  adopt: true // Adopts the existing resource if it already exists
});
