# 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.

# deltachat-jsonrpc
This crate provides a [JSON-RPC 2.0](https://www.jsonrpc.org/specification) interface to DeltaChat.
The JSON-RPC API is exposed in two fashions:
* The JSON-RPC API can be called through the [C FFI](../deltachat-ffi) with the functions `dc_jsonrpc_init`, `dc_jsonrpc_request`, `dc_jsonrpc_next_response` and `dc_jsonrpc_unref`.
* This crate includes a binary that serves the JSON-RPC API over a [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API).
We also include a JavaScript and TypeScript client for the JSON-RPC API. The source for this is in the [`typescript`](typescript) folder and published on NPM as `deltachat-jsonrpc`.
## Usage
### Running the WebSocket server
From within this folder, you can start the WebSocket server with the following command:
```sh
cargo run --features webserver
```
The server accepts WebSocket connections on `ws://localhost:20808/ws`.
If you are targetting other architectures (like KaiOS or Android), the webserver binary can be cross-compiled easily with [rust-cross](https://github.com/cross-rs/cross):
```sh
cross build --features=webserver --target armv7-linux-androideabi --release
```
### Running the example app
We include a small demo web application that talks to the WebSocket server. To run it, follow these steps:
* The package includes TypeScript bindings which are partially auto-generated through the JSON-RPC library used by this crate ([yerpc](https://github.com/Frando/yerpc/)).
```sh
cd typescript
npm install
npm run build
```
* Then, build and run the example application:
```sh
npm run example:dev
```

## Run the tests
### Rust tests
```
cargo test --features=webserver
```
### Typescript

npm run test
