Features:

• Adapters
• Pipes
• Payload Validation
• Modules
• Simplification
• Custom Decorators

Adapters

Package is router library agnostic so it's possible to use express, fastify or koa. In this release only ExpressAdapter is included, more to come.

Pipes

Reimagined middleware. Supports both running code before and after main handler. There are three types of pipes: global, controller and method at the moment.

Order of Execution:

Global => Controller => Method => Route Handler => Method => Controller => Global

Payload Validation

Based on class-validator and class-transformer system supports payload validation. Standard type validation (i.e. string, object, boolean etc.) is also supported.

@Post('', 200)
create(@Body() post: PostType) {
  return post;
}

@Get(':id', 200)
post(@Params('id') id: string) {
  return { id, name: 'hello world' };
}

Modules

Modules keep providers scoped. Resolved via update of @decorators/[email protected] version that supports nesting of containers. With 3.0.0 update is also possible to use multi providers (available through the same injection token).
