Middleware builder
Configure the middleware chain by calling use().
Then, execute() the chain: this will always return Promise<void>
await new MiddlewareBuilder <{someValue: string}> ()
.use(async (message, next) => {
message.someValue = 'hi';
await next();
})
.use((message, _) => {
message.someValue = 'bonjour';
})
.execute({someValue: 'hello'});
