TODO.md

Core system

• Base structure of JSON API code
• Implement the first methods for testing + the code that should later be generated by the proc macro
• Create the proc macro
  • json api
  • ts types
    • arguments (no args, one argument, multiple args)
    • return type
    • custom types as type aliases that ts file looks prettier

Pre - MVP

• Web socket server
• [WIP] Web socket client (ts)
  • backend connection state changed events
  • Reconnect on connection loss / connection state
  • find a way to type the event emitter callback functions
• Events

MVP

• mocha integration test for ts api
• basic tests
• advanced / "online tests" (mailadm for burner accounts)
• coverage for a majority of the API
• Blobs served
• Blob upload (for attachments, setting profile-picture, importing backup and so on)
• Web push API? At least some kind of notification hook closure this lib can accept.

Other Ideas

• make sure there can only be one connection at a time to the ws
  • why? , it could give problems if its commanded from multiple connections
• encrypted connection?
• authenticated connection?
• Look into unit-testing for the proc macros?
• proc macro taking over doc comments to generated typescript file
• GH action for tests (rust and typescript)
  • rust test
  • rust fmt
  • rust clippy
  • tsc check
  • prettier
  • mocha
• scripts to check&fix prettier formatting

Apis

replicate desktop api feature set:

(this feature set is based on desktop version 1.20, needs to be updated in the future)

struct sendMessageParams {
  text: Option<String>,
  filename: Option<String>, // TODO we need to think about blobs some more
  location: Option<(u32,u32)>,
  quote_message_id: Option<u32>,
}

struct QrCodeResponse = {
  state: u32 // also enum in reality, for simlicity u32 here
  id: u32
  text1: String
}

impl Api {

// root ---------------------------------------------------------------

// NEEDS_THE_BLOB_QUESTION_ANSWERED_EVENTUALLY
async fn sc_set_profile_picture(&self, new_image: String) -> Result<()> {}

// NEEDS_THE_BLOB_QUESTION_ANSWERED_EVENTUALLY
// 'getProfilePicture' equals to `dc.getContact(C.DC_CONTACT_ID_SELF).getProfileImage()` or `dc.get_config("selfavatar")`

async fn sc_join_secure_join(&self, qrCode: String) -> Result<u32> {}
async fn sc_stop_ongoing_process(&self) -> Result<u32> {}
async fn sc_check_qr_code(&self, qrCode: String) -> Result<QrCodeResponse> {}

// login ----------------------------------------------------

// INFO: login functions need to call stop&start io where applicable

// login.newLogin:
// do instead in frontend:
//   1. call `add_account`
//   2. call `select_account`
//   3. set credentials via set config
//   4. call `sc_configure`

// login.getLogins - is already implemented: `get_all_accounts`

// login.loadAccount - Basically `select_account`

// login.logout -> TODO: unselect account, which isn't implemented in the core yet

// login.forgetAccount -> `remove_account`

// login.getLastLoggedInAccount -> `get_selected_account_id`

// login.updateCredentials -> do instead: set config then call `sc_configure`

// backup -------------------------------------------------------------

// INFO: backup functions need to call stop&start io

// NEEDS_THE_BLOB_QUESTION_ANSWERED_EVENTUALLY
async fn sc_backup_export(&self, out_dir: String) -> Result<()> {}
// NEEDS_THE_BLOB_QUESTION_ANSWERED_EVENTUALLY
async fn sc_backup_import(&self, file: String) -> Result<()> {} // will not return the same as in desktop because this function imports backup to the current context unlike it was in desktop

// chatList -----------------------------------------------------------

// chatList.selectChat - will be removed from desktop
// chatList.getSelectedChatId - will be removed from desktop
// chatList.onChatModified - will be removed from desktop

async fn sc_chatlist_get_general_fresh_message_counter(&self) -> Result<u32> // this method might be used for a favicon badge counter

// contacts ------------------------------------------------------------

async fn sc_contacts_change_nickname(&self, contact_id: u32, new_name: String) -> Result<()>


// contacts.getChatIdByContactId - very similar to sc_contacts_create_chat_by_contact_id
// contacts.getDMChatId -  very similar to sc_contacts_create_chat_by_contact_id

async fn sc_contacts_get_encryption_info(&self, contact_id: u32) -> Result<String>

async fn sc_contacts_lookup_contact_id_by_addr(&self, email: String) -> Result<u32>

after that, or while doing it adjust api to be more complete

TODO different test to simulate two devices:

to test autocrypt_initiate_key_transfer & autocrypt_continue_key_transfer
