ajv-base64

Adds a base64 format to Ajv.

Install

npm install ajv-base64

or

yarn add ajv-base64

Note that this package isn't very useful without Ajv itself, so you should install that as well.

Setup

const Ajv = require("ajv");
const ajv = new Ajv();
require("ajv-base64")(ajv);

Usage

When defining your JSON schema, use the format keyword with the value set to base64. For example:

{
  "type": "object",
  "properties": {
    "cursor": {
      "type": "string",
      "format": "base64"
    }
  }
}

Valid data:

• { cursor: "YWJj" }
• { cursor: "SGVsbG8sIHdvcmxkIQ==" }

Invalid data:

• { cursor: "" }
• { cursor: "Hello, world!" }
• { cursor: "🔥" }
