* make sure to use dc_str_unref instead of free
on cstrings returned/owned by rust

thanks to ralphtheninja for finding them

this might have been the cause for the second segfault

* add webxdc methods to jsonrpc:
- `webxdc_send_status_update`
- `webxdc_get_status_updates`
- `message_get_webxdc_info`

* add `chat_get_media` to jsonrpc
also add viewtype wrapper enum and use it in `MessageObject`,
additionally to using it in `chat_get_media`

* use camelCase in all js object properties

* Add check_qr function to jsonrpc

* Fixed clippy errors and formatting

* Fixed formatting

* fix changelog ordering after rebase

# 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:
* A executable that exposes the JSON-RPC API through a [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) server running on localhost.
* The JSON-RPC API can also be called through the [C FFI](../deltachat-ffi). The C FFI needs to be built with the `jsonrpc` feature. It will then expose the functions `dc_jsonrpc_init`, `dc_jsonrpc_request`, `dc_jsonrpc_next_response` and `dc_jsonrpc_unref`. See the docs in the [header file](../deltachat-ffi/deltachat.h) for details.
We also include a JavaScript and TypeScript client for the JSON-RPC API. The source for this is in the [`typescript`](typescript) folder. The client can easily be used with the WebSocket server to build DeltaChat apps for web browsers or Node.js. See the [examples](typescript/example) for details.
## Usage
#### Running the WebSocket server
From within this folder, you can start the WebSocket server with the following command:
```sh
cargo run --features webserver
```
If you want to use the server in a production setup, first build it in release mode:
```sh
cargo build --features webserver --release
```
You will then find the `deltachat-jsonrpc-server` executable in your `target/release` folder.
The executable currently does not support any command-line arguments. By default, once started it will accept WebSocket connections on `ws://localhost:20808/ws`. It will store the persistent configuration and databases in a `./accounts` folder relative to the directory from where it is started.
The server can be configured with environment variables:
|variable|default|description|
|-|-|-|
|`DC_PORT`|`20808`|port to listen on|
|`DC_ACCOUNTS_PATH`|`./accounts`|path to storage directory|
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
```
#### Using the TypeScript/JavaScript client
The package includes a JavaScript/TypeScript client which is partially auto-generated through the JSON-RPC library used by this crate ([yerpc](https://github.com/Frando/yerpc/)). Find the source in the [`typescript`](typescript) folder.
To use it locally, first install the dependencies and compile the TypeScript code to JavaScript:
```sh
cd typescript
npm install
npm run build
```
The JavaScript client is not yet published on NPM (but will likely be soon). Currently, it is recommended to vendor the bundled build. After running `npm run build` as documented above, there will be a file `dist/deltachat.bundle.js`. This is an ESM module containing all dependencies. Copy this file to your project and import the DeltaChat class.
```typescript
import { DeltaChat } from './deltachat.bundle.js'
const dc = new DeltaChat('ws://localhost:20808/ws')
const accounts = await dc.rpc.getAllAccounts()
console.log('accounts', accounts)
```
A script is included to build autogenerated documentation, which includes all RPC methods:
```sh
cd typescript
npm run docs
```
Then open the [`typescript/docs`](typescript/docs) folder in a web browser.
## Development
#### Running the example app
We include a small demo web application that talks to the WebSocket server. It can be used for testing. Feel invited to expand this.
```sh
cd typescript
npm run build
npm run example:build
npm run example:start
```
Then, open [`http://localhost:8080/example.html`](http://localhost:8080/example.html) in a web browser.
Run `npm run example:dev` to live-rebuild the example app when files changes.
### Testing
The crate includes both a basic Rust smoke test and more featureful integration tests that use the TypeScript client.
#### Rust tests
To run the Rust test, use this command:
```
cargo test
```
#### TypeScript tests
```
cd typescript
npm run test
```
This will build the `deltachat-jsonrpc-server` binary and then run a test suite against the WebSocket server.
The test suite includes some tests that need online connectivity and a way to create test email accounts. To run these tests, talk to DeltaChat developers to get a token for the `testrun.org` service, or use a local instance of [`mailadm`](https://github.com/deltachat/docker-mailadm).
Then, set the `DCC_NEW_TMP_EMAIL` environment variable to your mailadm token before running the tests.
```
DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=yourtoken npm run test
```
#### Test Coverage
Running `npm run test` will report test coverage. For the coverage to be accurate the online tests need to be run.
> If you are offline and want to see the coverage results anyway (even though they are inaccurate), you can bypass the errors of the online tests by setting the `COVERAGE_OFFLINE=1` environment variable.
A summary of the coverage will be reported in the terminal after the test run. Open `coverage/index.html` in a web browser for a detailed report.
