[CMS][WP] Ability to view draft pages

[anuveyatsu]

When I'm preparing pages in the WordPress, I want to view draft pages in my staging/test site, so that I can make sure it looks great prior to publishing it in production.

Acceptance criteria

• [x] I can quickly configure my staging/test site to display draft pages

Tasks

• [x] Update docs at http://tech.datopian.com/frontend/plugins/#wp
  • [ ] It should explain how to use WP_SHOW_DRAFT
• [x] Use WP_SHOW_DRAFT env var as an option when hitting WP API
  • see status param in https://developer.wordpress.com/docs/api/1.1/get/sites/%24site/posts/

Analysis

Set up baseQuery in CMS model constructor so that it's used by all methods:

https://github.com/datopian/frontend-v2/blob/master/plugins/wp/cms.js#L9-L11

constructor() {
  this.blog = wpcom.site(config.get('WP_URL'))
  this.baseQuery = {
    status: 'publish' + config.get('WP_SHOW_DRAFT') ? ',draft' : ''
  }
}

Then it should be used by all methods:

async getListOfPostsWithMeta(query) {
  return await this.blog.postsList(Object.assign(this.baseQuery, query))
}
