// Javascript is generated from typescript, do not modify generated javascript because changes will be overwritten.
/*
Webmail is a self-contained webmail client.
Typescript is used for type safety, but otherwise we try not to rely on any
JS/TS tools/frameworks etc, they often complicate/obscure how things work. The
DOM and styles are directly manipulated, so to develop on this code you need to
know about DOM functions. With a few helper functions in the dom object,
interaction with the DOM is still relatively high-level, but also allows for
more low-level techniques like rendering of text in a way that highlights text
that switches unicode blocks/scripts. We use typescript in strict mode, see
top-level tsc.sh. We often specify types for function parameters, but not
return types, since typescript is good at deriving return types.
There is no mechanism to automatically update a view when properties change. The
UI is split/isolated in components called "views", which expose only their root
HTMLElement for inclusion in another component or the top-level document. A view
has functions that other views (e.g. parents) can call for to propagate updates
or retrieve data. We have these views:
- Mailboxlist, in the bar on the list with all mailboxes.
- Mailbox, a single mailbox in the mailbox list.
- Search, with form for search criteria, opened through search bar.
- Msglist, the list of messages for the selected mailbox or search query.
- Msgitem, a message in Msglist, shown as a single line.
- Msg, showing the contents of a single selected message.
- Compose, when writing a new message (or reply/forward).
Most of the data is transferred over an SSE connection. It sends the initial
list of mailboxes, sends message summaries for the currently selected mailbox or
search query and sends changes as they happen, e.g. added/removed messages,
changed flags, etc. Operations that modify data are done through API calls. The
typescript API is generated from the Go types and functions. Displayed message
contents are also retrieved through an API call.
HTML messages are potentially dangerous. We display them in a separate iframe,
with contents served in a separate HTTP request, with Content-Security-Policy
headers that prevent executing scripts or loading potentially unwanted remote
resources. We cannot load the HTML in an inline iframe, because the iframe "csp"
attribute to set a Content-Security-Policy is not supported by all modern
browsers (safari and firefox don't support it at the time of writing). Text
messages are rendered inside the webmail client, making URLs clickable,
highlighting unicode script/block changes and rendering quoted text in a
different color.
Browsers to test with: Firefox, Chromium, Safari, Edge.
To simulate slow API calls and SSE events:
localStorage.setItem('sherpats-debug', JSON.stringify({waitMinMsec: 2000, waitMaxMsec: 4000}))
Show additional headers of messages:
settingsPut({...settings, showHeaders: ['Delivered-To', 'User-Agent', 'X-Mailer', 'Message-Id', 'List-Id', 'List-Post', 'X-Mox-Reason', 'TLS-Required']})
Enable logging and reload afterwards:
localStorage.setItem('log', 'yes')
Enable consistency checking in UI updates:
settingsPut({...settings, checkConsistency: true})
- todo: in msglistView, show names of people we have sent to, and address otherwise. or at don't show names for first-time senders.
- todo: implement settings stored in the server, such as mailboxCollapsed, keyboard shortcuts. name to use for "From", optional default Reply-To and Bcc addresses, signatures (per address), configured labels/keywords with human-readable name, colors and toggling with shortcut keys 1-9.
- todo: automated tests? perhaps some unit tests, then ui scenario's.
- todo: composing of html messages. possibly based on contenteditable. would be good if we can include original html, but quoted. must make sure to not include dangerous scripts/resources, or sandbox it.
- todo: make alt up/down keys work on html iframe too. requires loading it from sameorigin, to get access to its inner document.
- todo: reconnect with last known modseq and don't clear the message list, only update it
- todo: find and use svg icons for flags in the msgitemView. junk (fire), forwarded, replied, attachment (paperclip), flagged (flag), phishing (?). also for special-use mailboxes (junk, trash, archive, draft, sent). should be basic and slim.
- todo: for embedded messages (message/rfc822 or message/global), allow viewing it as message, perhaps in a popup?
- todo: only show orange underline where it could be a problem? in addresses and anchor texts. we may be lighting up a christmas tree now, desensitizing users.
- todo: saved searches that are displayed below list of mailboxes, for quick access to preset view
- todo: when search on free-form text is active, highlight the searched text in the message view.
- todo: forwarding of html parts, including inline attachments, so the html version can be rendered like the original by the receiver.
- todo: buttons/mechanism to operate on all messages in a mailbox/search query, without having to list and select all messages. e.g. clearing flags/labels.
- todo: can we detect if browser supports proper CSP? if not, refuse to load html messages?
- todo: more search criteria? Date header field (instead of time received), text vs html (only, either or both), attachment filenames and sizes
- todo: import messages into specific mailbox?
- todo: configurable keyboard shortcuts? we use strings like "ctrl p" which we already generate and match on, add a mapping from command name to cmd* functions, and have a map of keys to command names. the commands for up/down with shift/ctrl modifiers may need special attention.
- todo: consider composing messages with bcc headers that are sent as message Bcc headers to the bcc-addressees, optionally with checkbox.
- todo: improve accessibility
- todo: msglistView: preload next message?
- todo: previews of zip files
- todo: undo?
- todo: mobile-friendly version. should perhaps be a completely different app, because it is so different.
