The Directive
The Directive is a declarative file that allows you to describe your application's business logic. By describing your application declaratively, you can avoid all of the boilerplate code that normally comes with building a web service such as binding to ports, setting up TLS, constructing a router, etc.
Here's an example Directive:
1
identifier: com.suborbital.guide
2
appVersion: v0.0.1
3
atmoVersion: v0.3.2
4
​
5
handlers:
6
  - type: request
7
    resource: /hello
8
    method: POST
9
    steps:
10
      - group:
11
        - fn: modify-url
12
        - fn: helloworld-rs
13
          onErr:
14
            any: continue
15
​
16
      - fn: fetch
17
​
18
  - type: request
19
    resource: /set/:key
20
    method: POST
21
    steps:
22
      - fn: cache-set
23
​
24
  - type: request
25
    resource: /get/:key
26
    method: GET
27
    steps:
28
      - fn: cache-get

This directive encapsulates all of the logic for your application. It describes three endpoints and the logic needed to handle them. Each handler describes a set of steps that composes a series of Runnables to handle the request.
Atmo uses the Directive to build your application and run it automatically, without any need to write boilerplate yourself.
