Desirae
=====
(in development)
A blog platform built for Developers, but with normal people in mind.
Desirae runs entirely in the browser, but needs a little help from Node.js for saving and retrieving files.
She can also be run from entirely headless from node.js.
Key Features
------------
Really good use of `try { ... } catch(e) ...` - it won't all blow up at the slightest parse error (*cough* ruhoh *cough* jekyll)... bless me.
JavaScript - it's so stable it takes 10 years to get new any features. Won't break every time you upgrade OS X and reinstall brew (*cough* ruby).
Browser (optional) - using your front-end templates to build in your front-end? Imagine that!
Node (optional) - if you'd prefer to go headless, you can.
The server is *very* minimal and could easily be implemented in any language (such as ruby or python).
Configuration
=============
There are a few configuration files:
* `site.yml` is stuff that might be unique to your site, such as (title, url, adwords id, etc)
* `authors/<<your-handle.yml>>` contains information about you (name, handle, facebook, etc)
* `desirae.yml` contains directives that describe *how* the blog should be compiled - more technical stuff.
If any of these files change, the entire site needs to be retemplated.
Server
======
Obviously there has to be a server with some sort of storage and retrieval mechanism.
I've implemented a very simple node server using the filesystem.
GET /api/fs/walk
------------
`GET http://local.dear.desi:8080/api/fs/walk?dir=posts&dotfiles=true&extensions=md,markdown,jade,htm,html`
* `dir` **must** be supplied. returns a flat list of all files, recursively
* `dotfiles` default to `false`. includes dotfiles when `true`.
* `extensions` defaults to `null`. inclode **only** the supplied extensions when `true`.
```json

To retrieve multiple dir listings at once:
* for a few simple dirs without special chars just change `dir` to `dirs` and separate with commas
`GET http://local.dear.desi:8080/api/fs/walk?dirs=posts/2015,posts/2013&dotfiles=true&extensions=md,markdown,jade,htm,html`
* for many dirs, or dirs with special chars, `POST` an object containing an array of `dirs` with `&_method=GET` appended to the url.
```
POST http://local.dear.desi:8080/api/fs/walk?dotfiles=true&extensions=md,markdown,jade,htm,html&_method=GET
{ "dirs": [ "old", "2013,12", "2013,11" ] }
```
```javascript
{
"posts/2015": [ { "name": ... }, { ... } ]
, "posts/2013": [ ... ]
}
```
GET /api/fs/files
-------------
`GET http://local.dear.desi:8080/api/fs/files?path=posts/happy-new-year.md`
```json

}
```
To retrieve multiple files at once:
* for a few simple files without special chars just change `path` to `paths` and separate with commas
`GET http://local.dear.desi:8080/api/fs/files?paths=posts/foo.md,posts/bar.md`
* for many files, or files with special chars, `POST` an object containing an array of `pathss` with `&_method=GET` appended to the url.
```
POST http://local.dear.desi:8080/api/fs/files?dotfiles=true&extensions=md,markdown,jade,htm,html&_method=GET
{ "paths": [ "posts/foo.md", "posts/2013,11,30.md" ] }
```
```json
[
{ "path": "posts/foo.md"

POST /api/fs/files
------------------
By default this should assume that you intended to write to the compiled directory
and return an error if you try to write to any other directory, unless `compiled=false` (not yet implemented).
`_method=PUT` is just for funzies.
Including `sha1` is optional, but recommended.
`lastModifiedDate` is optional and may or may not make any difference.
`strict` (not yet implemented) fail immediately and completely on any error
```json
POST http://local.dear.desi:8080/api/fs/files?compiled=true&_method=PUT
{
"files": [
{ "path": "posts/foo.md"
, "name": "foo.md"
, "relativePath": "posts"
, "createdDate": "2013-08-01T22:47:37.000Z"
, "lastModifiedDate": "2013-08-01T22:47:37.000Z"
, "contents": "..."
, "sha1": "6eae3a5b062c6d0d79f070c26e6d62486b40cb46"
, "delete": false
}
, ...
]
}
```
The response may include errors of all shapes and sizes.
```json
{ "error": { message: "any top-level error", ... }
, "errors": [
{ "type": "file|directory"
, "message": "maybe couldn't create the directory, but maybe still wrote the file. Maybe not"
}
, ...
]
}
```
POST /api/fs/copy
------------------
```json
{ files: { "assets/logo.png": "compiled/assets/logo.png" } }
```
TODO
----
**TODO** Allow rename and delete?
option for client write to a hidden `.desi-revisions` (as well as indexeddb)
to safeguard against accidental blow-ups for people who aren't using git.
