snlhnk c05c0d3df6 Module-ize server routes, add static file support and other enhancements(#2679)
* Module-ize server routes and add static file support (#2510)

* Refactor server routes to modules

New module type: serverroute

Caveats: Loading order is not deterministic but this would only matter
if two route modules attempted to use the same path regexp (that would
be silly).

* Add static assets plugin

This plugin allows the node server to fetch static assets in the /assets
directory. I felt that this was a feature that goes above the core
functionality. That is why I added it as a plugin. with the modular
route extensions this was a breeze.

* Add serverroute description to ModuleTypes

* Coding standards tweaks

* Fix filename typo

* Move support for attachments from a plugin into the core

* Missing "else"

* Refactor server handling

* Introduce a new named parameter scheme for commands
* Move the SimpleServer class into it's own module
* Deprecate the --server command because of the unwieldy syntax
* Add a new --listen command using the new syntax

For example:

tiddlywiki mywiki --listen host:0.0.0.0 port:8090

* Add check for unknown parameters

* Add support for multiple basic authentication credentials in a CSV file

Beware: Passwords are stored in plain text. If that's a problem, use an authenticating proxy and the trusted header authentication approach.

* Refactor module locations

* Rename "serverroute" module type to "route"

* Remove support for verifying optional named command parameters

The idea was to be able to flag unknown parameter names, but requiring a command to pre-specify all the parameter names makes it harder for (say) the listen command to be extensible so that plugins can add new optional parameters that they handle. (This is particularly in the context of work in progress to encapsulate authenticators into their own modules).

* Refactor the two authenticators into separate modules and add support for authorization

* Correct mistaken path.join vs. path.resolve

See https://stackoverflow.com/a/39836259

* Docs for the named command parameters

I'd be grateful if anyone with sufficient Windows experience could confirm that the note about double quotes in "NamedCommandParameters" is correct.

* Be consistent about lower case parameter names

* Do the right thing when we have a username but no password

With a username parameter but no password parameter we'll attribute edits to that username, but not require authentication.

* Remove obsolete code

* Add support for requiring authentication without restricting the username

* Refactor authorization checks

* Return read_only status in /status response

* Fix two code typos

* Add basic support for detecting readonly status and avoiding write errors

We now have syncadaptors returning  readonly status and avoid attempting to write to the server if it's going to fail

* Add readonly-styles

We hide editing-related buttons in read only mode

I've made this part of the tiddlyweb plugin but I think a case could be made for putting it into the core.

* Add custom request header as CSRF mitigation

By default we require the header X-Requested-With to be set to TiddlyWiki. Can be overriden by setting csrfdisable to "yes"

See https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)_Prevention_Cheat_Sheet#Protecting_REST_Services:_Use_of_Custom_Request_Headers

* Add support for HTTPS

* First pass at a route for serving rendered tiddlers

* Tweaks to the single tiddler static view

Adding a simple sidebar

* Switch to "dash" separated parameter names

* Typo

* Docs: Update ServerCommand and ListenCommand

* First pass at docs for the new web server stuff

Writing the docs is turning out to be quite an undertaking, much harder than writing the code!

* Get rid of extraneous paragraphs in static renderings

* Rejig anonymous user handling

Now we can support wikis that are read-only for anonymous access, but allow a user to login for read/write access.

* More docs

Slowly getting there...

* Static tiddler rendering: Fix HTML content in page title

* Docs updates

* Fix server command parameter names

Missed off 30ce7ea

* Docs: Missing quotes

* Avoid inadvertent dependency on Node.js > v9.6.0

The listenOptions parameter of the plain HTTP version of CreateServer was only introduced in v9.6.0

cc @Drakor @pmario

* Typo

title: NamedCommandParameters
type: text/vnd.tiddlywiki
<<.from-version "5.1.18">> Most TiddlyWiki [[Commands]] use a position-based system for their parameters where each parameter must be listed in the precise order defined by the command. Some of the more complex commands offer an alternative scheme of named command parameters. For example, here we provide two parameters named "port" and "host":
```
--listen port=8090 host=0.0.0.0
```
Note that the order of the parameters does not matter.
Using special characters within a parameter requires quoting. Unix, Linux and the Mac use single quotes, and Windows uses double quotes:
```
--listen port=8090 username=joe 'password=s3cret(!'
--listen port=8090 username=joe "password=s3cret(!"
```
Note that the quotes are applied to the entire name=value pair, not just to the value part.
