TypeScript

Types are included in this project, and they also work with plugins.

Just pass the types that your plugin will add to context as a generic. This will be overlayed on top of any types added by previous plugins in the chain.

E.g.

const addSessionData: Plugin<{ session: { userId: string } } }> = (context, next) => {
  context.session = { userId: 'some-user' };
};

const res = await client
  .use(addSessionData)
  .use((context, next) => {
    if (context.session.userId === 'some-user') { // this would error if addSessionData middleware was missing
      // do something
    }
  })
  .use<{res: { random: number } }>((context, next) => {
    context.res.random = Math.random();
  })
  .get(url)
  .asResponse();

console.log(res.random); // number

Opting Out

If you don't want to type your plugin, simply use any as the type. This is not recommended though as it means all plugins later in the chain will lose the types too, because they have no idea what changes were made.

const myPlugin: Plugin<any> = (context, next) => {};
