+# deltachat-jsonrpc
+
+## Build Requirements
+
+- Linux or Mac, scrips make use of features like `>` pipes and `&&` (maybe the newer versions of powershell support them, but I didn't try that.)
+- rust (installed via rustup)
+
+## Start the webserver
+
+The webserver is an example usage. Goal of it is to be usable both as example and as base for deltachat-kaiOS.
+
+```sh
+RUST_LOG=info cargo run --features webserver
+```
+
+## Generate Typescript Bindings
+
+```sh
+cd typescript
+npm i
+npm run build
+```
+
+## Run the development example
+
+Mac
+
+```sh
+alias firefox=/Applications/Firefox.app/Contents/MacOS/firefox
+npm run example:build && firefox --devtools $(pwd)/example/browser-example.html
+```
+
+Linux:
+
+```sh
+npm run example:run
+```
+
+## Compiling server for kaiOS or android:
+
+```sh
+cross build --features=webserver --target armv7-linux-androideabi --release
+```
+
+## Run the tests
+
+### Rust tests
+
+```
+cargo test --features=webserver
+```
+
+### Typescript
+
+```
+cd typescript
+npm run test
+```
+
+For the online tests to run you need a test account token for a mailadm instance,
+you can use docker to spin up a local instance: https://github.com/deltachat/docker-mailadm
+
+> set the env var `DCC_NEW_TMP_EMAIL` to your mailadm token: example:
+> `DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=1h_195dksa6544`
+
+If your test fail with server shutdown at the start, then you might have a process from a last run still running probably and you need to kill that process manually to continue.
+
+#### Test Coverage
+
+You can test coverage with `npm run coverage`, but you need to have `DCC_NEW_TMP_EMAIL` set, otherwise the result will be useless because some functions can only be tested with the online tests.
+
+> If you are offline and want to see the coverage results anyway (even though they are NOT correct), you can bypass the error with `COVERAGE_OFFLINE=1 npm run coverage`
+
+Open `coverage/index.html` for a detailed report.
+`bindings.ts` is probably the most interesting file for coverage, because it describes the api functions.

+## Core system
+
+- [X] Base structure of JSON API code 
+- [X] Implement the first methods for testing + the code that should later be generated by the proc macro
+- [X] Create the proc macro
+  - [X] json api
+  - [X] ts types
+    - [X] arguments (no args, one argument, multiple args)
+    - [X] return type
+    - [X] custom types as type aliases that ts file looks prettier
+
+
+## Pre - MVP
+
+- [X] Web socket server
+- [WIP] Web socket client (ts)
+  - [X] backend connection state changed events
+  - [X] Reconnect on connection loss / connection state
+  - [ ] find a way to type the event emitter callback functions
+- [X] Events
+
+## MVP
+
+- [X] mocha integration test for ts api
+ - [X] basic tests
+ - [X] 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
+- [X] GH action for tests (rust and typescript)
+  - [X] rust test
+  - [X] rust fmt
+  - [X] rust clippy
+  - [X] tsc check
+  - [X] prettier
+  - [X] mocha
+- [X] scripts to check&fix prettier formatting

+## Other APIs and Tags Usage Hints
+
+- `localStorage`, `sessionStorage`, `indexedDB` are okay to be used
+- `visibilitychange`-events are okay to be used
+- `window.navigator.language` is okay to be used, on desktop it is the system language
+- `<a href="localfile.html">` and other internal links are okay to be used
+- `<a href="mailto:addr@example.org?body=...">`- mailto links are okay to be used
+- `<meta name="viewport" ...>` usage is okay to be used
+  and useful esp. different webviews have different defaults
+
+
+### Discouraged Things
+
+- `document.cookie` is known not to work on desktop and iOS
+  use `localStorage` instead
+- `unload`-, `beforeunload`- and `pagehide`-events are known not to work on iOS and are flaky on other systems
+  (also partly discouraged by [mozilla](https://developer.mozilla.org/en-US/docs/Web/API/Window/unload_event))
+  use `visibilitychange` instead
+- `<title>` and `document.title` is ignored by Webxdc;
+  use the `name` property from `manifest.toml` instead
+- newest js features may not work on all webviews,
+  you may want to transpile your code down to an older js version
+  eg. with <https://babeljs.io>
+- `<a href="https://example.org/foo">` and other external links are blocked by definition;
+  instead, embed content or use `mailto:` link to offer a way for contact
+- `<input type="file">` is discouraged currently; this may change in future
+

- older devices might not have the newest js features in their webview,
-  you may want to transpile your code down to an older js version eg. with https://babeljs.io
- viewport and scaling features are implementation specific,
-  if you want to have an explicit behavior, you can add eg.
-  `<meta name="viewport" content="initial-scale=1; user-scalable=no">` to your Webxdc
- the `<title>` tag should not be used and its content is usually not displayed;
-  instead, use the `name` property from `manifest.toml`
- there are tons of ideas for enhancements of the API and the file format,
-  eg. in the future, we will may define icon- and manifest-files,
-  allow to aggregate the state or add metadata.

+### Use a git branch in deltachat-desktop
+
+You can directly install a core branch, but make sure:
+- that you have typescript in your project dependencies, as it is likely required
+- you know that there are **no prebuilds** and so core is built during installation which is why it takes so long
+
+```
+npm install https://github.com/deltachat/deltachat-core-rust.git#branch

+If you want prebuilds for a branch that has a core pr, you might find an npm tar.gz package for that branch at <https://download.delta.chat/node/preview/>.
+The github ci also posts a link to it in the checks for each pr.
