## npm package for deltachat-rpc-server
|
|
|
|
This is the successor of `deltachat-node`,
|
|
it does not use NAPI bindings but instead uses stdio executables
|
|
to let you talk to core over jsonrpc over stdio.
|
|
This simplifies cross-compilation and even reduces binary size (no CFFI layer and no NAPI layer).
|
|
|
|
## Usage
|
|
|
|
> The **minimum** nodejs version for this package is `16`
|
|
|
|
```
|
|
npm i @deltachat/stdio-rpc-server @deltachat/jsonrpc-client
|
|
```
|
|
|
|
```js
|
|
import { startDeltaChat } from "@deltachat/stdio-rpc-server";
|
|
import { C } from "@deltachat/jsonrpc-client";
|
|
|
|
async function main() {
|
|
const dc = await startDeltaChat("deltachat-data");
|
|
console.log(await dc.rpc.getSystemInfo());
|
|
dc.close()
|
|
}
|
|
main()
|
|
```

## How does it work when you install it
|
|
|
|
NPM automatically installs platform dependent optional dependencies when `os` and `cpu` fields are set correctly.
|
|
|

|
|
|
|
When you import this package it searches for the rpc server in the following locations and order:
|
|
|
|
1. `DELTA_CHAT_RPC_SERVER` environment variable
|
|
2. use the PATH when `{takeVersionFromPATH: true}` is supplied in the options.
|
|
3. prebuilds in npm packages
|
|
|
|
so by default it uses the prebuilds.
|
|
|
|
## How do you built this package in CI
|
|
|
|
- To build platform packages, run the `build_platform_package.py` script:
|
|
```
|
|
python3 build_platform_package.py <cargo-target>
|
|
# example
|
|
python3 build_platform_package.py x86_64-apple-darwin
|
|
```
|
|
- Then pass it as an artifact to the last CI action that publishes the main package.
|
|
- upload all packages from `deltachat-rpc-server/npm-package/platform_package`.
|
|
- then publish `deltachat-rpc-server/npm-package`,
|
|
- this will run `update_optional_dependencies_and_version.js` (in the `prepack` script),
|
|
which puts all platform packages into `optionalDependencies` and updates the `version` in `package.json`
|
|
|
|
## How to build a version you can use localy on your host machine for development
|
|
|
|
You can not install the npm packet from the previous section locally, unless you have a local npm registry set up where you upload it too. This is why we have seperate scripts for making it work for local installation.
|
|
|
|
- If you just need your host platform run `python scripts/make_local_dev_version.py`
|
|
- note: this clears the `platform_package` folder
|
|
- (advanced) If you need more than one platform for local install you can just run `node scripts/update_optional_dependencies_and_version.js` after building multiple plaftorms with `build_platform_package.py`
