SWC Macro

A plugin to replace .env variables in a certain manner. Initially proposed in #77. Initial design used regex to replace anything surrounded by handlebars. I think we should use deno_swc which will allow us to instead replace Deno.env. anything. We could possibly look into requiring ALEPH_PUBLIC_ prefix to .env variables unless it is accessed inside a useDeno hook.

for example, we can transform graphql string to AST at build time with macro:

import gql from 'https://deno.land/x/aleph/macros/graphql.macro.ts'

const query = gql`
  {
    user(id: 123) {
      firstName
      lastName
    }
  }
`

output code:

const query = {
  "kind": "Document",
  "definitions": [ ... ]
}

i perfer a new concept swc-marco can be a solution:

import env from 'https://deno.land/x/aleph/swc-macros/env.macro.ts'

const value = env('KEY')

it will be transpiled to below code:

const value = __ALEPH_ENV.get('KEY')

and the macro will export the deno.env as __ALEPH_ENV.

what do you think? @shadowtime2000 @alfredosalzillo
