A hacky but working solution to call D1 from a Durable Object

d1-from-do.ts

// our DO class
export class SomeDurableObject {
  // should upgrade to explicit type in prod
  env: any;

  constructor(_controller, env) {
    this.env = env;
  }

  // manually make request to D1 binding
  async executeSQL(name: string, sql: string): Promise<any> {
    return await this.env[`__D1_BETA__${name}`].fetch(`/query`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({ sql }),
    });
  }

  async fetch(_request) {
    // specify the binding name and sql we want to execute
    const bindingName = "DB";
    const query = `SELECT * FROM contacts`;
    const response = await this.executeSQL(bindingName, query);

    // deconstruct response
    const { results } = response;

    // return it 💪
    return new Response(JSON.stringify(results), { status: 200 });
  }
}
