+name: Prepare Crypto-Node.js Release
+# 
+#  This is a helper workflow to craft a new Node.js release, trigger this via
+#  the Github Workflow UI by dispatching it manually. Provide the version, the 
+#  matrix-sdk-crypto-nodejs npm package should be set to, and a optionally the
+#  old version (as used in the git tag) this release should be compared to.
+#
+#  This will then:
+#    1. bump the npm version to the one you specified
+#    2. commit that change together with the changelog (if it changed, see below)
+#    3. create the appropriate tag on that commit
+#    4. create the Github draft release, including the changes (if given, see below)
+#    5. push these to a new branch, including tag, triggering the `release-crypto-nodejs` workflow
+#    6. create a PR to merge these back into `main`
+#
+#  Additionally, if you provide a tag to comapare this tag to, this will:
+#    1. create a changelog between the two releases, used for the github release
+#    2. update the Changelog.md and include it in the commit
+#
+#  The remaining tasks are done by the release-crypto-nodejs workflow.

-## Chat rooms
-
-In addition to our [main Matrix room], we have a development room at
-[#matrix-rust-sdk-dev:flipdot.org]. Please use it to discuss potential changes,
-the overall direction of development and related topics.

-## Testing
-
-You can run most of the tests that also happen in CI also using
-`cargo xtask ci`. This needs a few dependencies to be installed, as it also runs
-automatic WASM tests:
-
-```bash
-rustup component add clippy
-cargo install cargo-nextest typos-cli wasm-pack
-```
-
-If you want to execute only one part of CI, there are a few sub-commands (see
-`cargo xtask ci --help`).
-
-Some tests are not automatically run in `cargo xtask ci`, for example the
-integration tests that need a running synapse instance. These tests reside in
-`./testing/matrix-sdk-integration-testing`. See its
-[README](./testing/matrix-sdk-integration-testing/README.md) to easily set up a
-synapse for testing purposes.

-## Introduction
-**matrix-rust-sdk** leverages [UniFFI](https://mozilla.github.io/uniffi-rs/) to generate bindings for host languages (eg. Swift and Kotlin).
-
-Rust code related with bindings live in the [matrix-rust-sdk/bindings](https://github.com/matrix-org/matrix-rust-sdk/tree/main/bindings) folder.
-
-Developers can expose Rust code to UniFFI using two different approaches:
- Using an `.udl` file. When a crate has one, you find it under the `src` folder (an example is [here](https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/api.udl)).
- Add UniFFI directivies as Rust attributes. In this case Rust source files (`.rs`) contain attributes related to UniFFI (e.g. `#[uniffi::export]`). Attributes are preferred, where applicable.
- 
-
-## Expose Rust definitions to UniFFI
-
-### Check if the API is already on UniFFI
-
-First of all check if the Rust definition you are looking for exists on UniFFI already. Most of exposed matrix definitions are collected in the crate [matrix-sdk-ffi](https://github.com/matrix-org/matrix-rust-sdk/tree/main/bindings/matrix-sdk-ffi).
-This crate contains mainly small Rust wrappers around the actual Rust SDK (e.g. the crate [matrix-sdk](https://github.com/matrix-org/matrix-rust-sdk/tree/main/crates/matrix-sdk))
-
-If the Rust definition is on UniFFI already, you either:
- find it in a `.udl` file like [matrix-sdk-ffi/src/api.udl](https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/api.udl)
- see it marked with a proper UniFFI Rust attribute like this `#[uniffi::export]`
-
-
-### Adding a missing matrix API
-
-1. Unless you want to contribute on the crypto side, you probably need to add some code in the [matrix-sdk-ffi](https://github.com/matrix-org/matrix-rust-sdk/tree/main/bindings/matrix-sdk-ffi) crate. After you find the crate you need to understand which file is best to contain the new Rust definition. When exposing new matrix API often (but not always) you need to touch the file [client.rs](https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/client.rs)
-
-2. Identify the API to expose in the target Rust crate (typically in [matrix-sdk](https://github.com/matrix-org/matrix-rust-sdk/tree/main/crates/matrix-sdk). If you can’t find it, you probably need to touch the actual Rust SDK as well. In this case you typically just need to write some code around [ruma](https://github.com/ruma/ruma) (a Rust SDK’s dependency) which already implements most of the matrix protocol
-
-3. After you got (by finding or writing) the required Rust code, you need to expose to UniFFI. To do that just write a small Rust wrapper in the related UniFFI crate (most of the time is **matrix-sdk-ffi**) you found on step 1.
-
-4. When your new (wrapping) Rust definition is ready, remember to expose it to UniFFI.
-It’s best to do it using UniFFI Rust attributes (e.g. `#[uniffi::export]`). Otherwise add the new definition in the crate’s `.udl` file. For the **matrix-sdk-ffi** crate the definition file is [api.udl](https://github.com/matrix-org/matrix-rust-sdk/blob/main/bindings/matrix-sdk-ffi/src/api.udl). **Remember**: the language inside a `.udl` file isn’t Rust. To learn more about how map Rust into UDL read [here](https://mozilla.github.io/uniffi-rs/udl_file_spec.html)
-
-## FAQ
-
-**Q**: I wrote my Rust code and exposed it to UniFFI. How can I check if the compiler is happy?\
-**A**: Run `cargo build` in the crate you touched (e.g. matrix-sdk-ffi). The compiler will complain if the Rust code and/or the `.udl` is wrong.
-
-
-**Q**: The compiler is happy with my code but the CI is failing on GitHub. How can I fix it?\
-**A**: The CI may fail for different reasons, you need to have a look on the failing GitHub workflow. One common reason though is that the linter ([Clippy](https://github.com/rust-lang/rust-clippy)) isn’t happy with your code. If this is the case, you can run `cargo clippy` in the crate you touched to see what’s wrong and fix it accordingly.

 This project and build script demonstrate how to create an XCFramework that can be imported into an Xcode project and run on Apple platforms. It can compile and bundle an [entire SDK](#Building-the-SDK), or only a smaller [Crypto module](#Building-only-the-Crypto-SDK) that provides end-to-end encryption for clients that already depend on an SDK (e.g. [Matrix iOS SDK](https://github.com/matrix-org/matrix-ios-sdk))

+It makes the compiled code available to swift by importing the C header through its bridging header.
+
+Once all the generated components are available running it should be as easy as choosing a platform and clicking run.

 ## Distribution

-The generated framework and Swift code can be distributed and integrated directly but in order to make things simpler we bundle them together as a [Swift package](https://github.com/matrix-org/matrix-rust-components-swift/) in the case of SDK, and as a CocoaPods podspec in the case of Crypto SDK.
-
-### Publishing MatrixSDKCrypto
-
-1. Navigate into `bindings/apple` and run [`build_crypto_xcframework.sh`](#building-only-the-crypto-sdk) script which generates a .zip file with the framework in `./generated` folder
-
-   Note that whilst you can run this command from any git branch, if you want to make a public release, ensure you are building from latest `main`
-
-2. Tag the commit you just used to build the release and push the tag to GitHub
-
-   Use `matrix-sdk-crypto-ffi-<major>.<minor>.<patch>` tag name
-
-3. Create a new [GitHub release](https://github.com/matrix-org/matrix-rust-sdk/releases) using this tag (see [example](https://github.com/matrix-org/matrix-rust-sdk/releases/tag/matrix-sdk-crypto-ffi-0.3.4))
-4. Upload the previously generated .zip file to this release
-5. Increment the version in [`MatrixSDKCrypto.podspec`](./MatrixSDKCrypto.podspec)
-
-   Note that this is not automated and is a local-only change. To determine the most recent published version, run `pod repo update && pod search MatrixSDKCrypto`
-   or check git tags via `git tag | grep matrix-sdk-crypto-ffi`
-
-6. Push new Podspec version to Cocoapods via `pod trunk push MatrixSDKCrypto.podspec --allow-warnings`

+# `matrix-sdk-crypto-js`
+
+Welcome to the [WebAssembly] + JavaScript binding for the Rust
+[`matrix-sdk-crypto`] library! WebAssembly can run anywhere, but these
+bindings are designed to run on a JavaScript host. These bindings are
+part of the [`matrix-rust-sdk`] project, which is a library
+implementation of a [Matrix] client-server.
+
+`matrix-sdk-crypto` is a no-network-IO implementation of a state
+machine, named `OlmMachine`, that handles E2EE ([End-to-End
+Encryption](https://en.wikipedia.org/wiki/End-to-end_encryption)) for
+[Matrix] clients.
+
+## Usage
+
+These WebAssembly bindings are written in [Rust]. To build them, you
+need to install the Rust compiler, see [the Install Rust
+Page](https://www.rust-lang.org/tools/install). Then, the workflow is
+pretty classical by using [npm], see [the Downloading and installing
+Node.js and npm
+Page](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
+
+Once the Rust compiler, Node.js and npm are installed, you can run the
+following commands:
+
+```sh
+$ npm install
+$ npm run build
+$ npm run test
+```
+
+A `matrix_sdk_crypto.js`, `matrix_sdk_crypto.d.ts` and a
+`matrix_sdk_crypto_bg.wasm` files should be generated in the `pkg/`
+directory.
+
+TBD
+
+## Documentation
+
+[The documentation can be found
+online](https://matrix-org.github.io/matrix-rust-sdk/bindings/matrix-sdk-crypto-js/).
+
+To generate the documentation locally, please run the following
+command:
+
+```sh
+$ npm run doc
+```
+
+The documentation is generated in the `./docs` directory.

+# Matrix-Rust-SDK Node.js Bindings
+
+## 0.1.0-beta.1 - 2022-07-14
+
+- Fixing broken download link, [#842](https://github.com/matrix-org/matrix-rust-sdk/issues/842)
+
+## 0.1.0-beta.0 - 2022-07-12
+
+Welcome to the first release of `matrix-sdk-crypto-nodejs`. This is a
+Node.js binding for the Rust `matrix-sdk-crypto` library. This is a
+no-network-IO implementation of a state machine, named `OlmMachine`,
+that handles E2EE (End-to-End Encryption) for Matrix clients.
+
+The goal of this binding is _not_ to cover the entirety of the
+`matrix-sdk-crypto` API, but only what's required to build Matrix bots
+or Matrix bridges (i.e. to connect different networks together via the
+Matrix protocol).
+
+This project replaces and deprecates a previous project, with the same
+name and same goals, inside [the `matrix-rust-sdk-bindings`
+repository](https://github.com/matrix-org/matrix-rust-sdk-bindings),
+with the NPM package name `@turt2live/matrix-sdk-crypto-nodejs`. The
+The new official package name is
+`@matrix-org/matrix-sdk-crypto-nodejs`.
+
+Note: All bindings are now part of [the `matrix-rust-sdk`
+repository](https://github.com/matrix-org/matrix-rust-sdk) (see the
+`bindings/` root directory).
+
+[A documentation is available inside the new
+`matrix-sdk-crypto-nodejs`
+project](https://github.com/matrix-org/matrix-rust-sdk/tree/0bde5ccf38f8cda3865297a2d12ddcdaf4b80ca7/bindings/matrix-sdk-crypto-nodejs).

+# `matrix-sdk-crypto-nodejs`
+
+Welcome to the [Node.js] binding for the Rust [`matrix-sdk-crypto`]
+library! This binding is part of the [`matrix-rust-sdk`] project,
+which is a library implementation of a [Matrix] client-server.
+
+`matrix-sdk-crypto-nodejs` is a no-network-IO implementation of a
+state machine, named `OlmMachine`, that handles E2EE ([End-to-End
+Encryption](https://en.wikipedia.org/wiki/End-to-end_encryption)) for
+[Matrix] clients.
+
+## Usage
+
+Just add the latest release to your `package.json`:
+```sh
+$ npm install --save @matrix-org/matrix-sdk-crypto-nodejs
+```
+
+When installing, NPM will download the corresponding prebuilt Rust library for your current host system. The following are supported:
+
+<table>
+  <thead>
+    <tr>
+      <th>Platform</th>
+      <th>Architecture</th>
+      <th>Triple</th>
+      <th>Prebuilt available</th>

+
+## Development
+
+This Node.js binding is written in [Rust]. To build this binding, you
+need to install the Rust compiler, see [the Install Rust
+Page](https://www.rust-lang.org/tools/install). Then, the workflow is
+pretty classical by using [npm], see [the Downloading and installing
+Node.js and npm
+Page](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
+
+The binding is compatible with, and tested against, the Node.js
+versions that are in “current”, “active” or “maintenance” states,
+according to [the Node.js Releases
+Page](https://nodejs.org/en/about/releases/), _and_ which are
+compatible with [NAPI v6 (Node.js
+API)](https://nodejs.org/api/n-api.html#node-api-version-matrix). It
+means that this binding will work with the following versions: 14.0.0,
+16.0.0 and 18.0.0.
+
+Once the Rust compiler, Node.js and npm are installed, you can run the
+following commands:
+
+```sh
+$ npm install --ignore-scripts
+$ npm run build
+$ npm run test
+```
+
+An `index.js`, `index.d.ts` and a `*.node` files should be
+generated. At the same level of those files, you can edit a file and
+try this:
+
+```javascript
+const { OlmMachine } = require('./index.js');
+
+// Let's see what we can do.
+```
+
+The `OlmMachine` state machine works in a push/pull manner:
+
+* You push state changes and events retrieved from a Matrix homeserver
+  `/sync` response, into the state machine,
+  
+* You pull requests that you will need to send back to the homeserver
+  out of the state machine.
+  
+```javascript
+const { OlmMachine, UserId, DeviceId, RoomId, DeviceLists } = require('./index.js');
+
+async function main() {
+    // Define a user ID.
+    const alice = new UserId('@alice:example.org');
+
+    // Define a device ID.
+    const device = new DeviceId('DEVICEID');
+
+    // Let's create the `OlmMachine` state machine.
+    const machine = await OlmMachine.initialize(alice, device);
+
+    // Let's pretend we have received changes and events from a
+    // `/sync` endpoint of a Matrix homeserver, …
+    const toDeviceEvents = "{}"; // JSON-encoded
+    const changedDevices = new DeviceLists();
+    const oneTimeKeyCounts = {};
+    const unusedFallbackKeys = [];
+
+    // … and push them into the state machine.
+    const decryptedToDevice = await machine.receiveSyncChanges(
+        toDeviceEvents,
+        changedDevices,
+        oneTimeKeyCounts,
+        unusedFallbackKeys,
+    );
+
+    // Now, let's pull requests that we need to send out to the Matrix
+    // homeserver.
+    const outgoingRequests = await machine.outgoingRequests();
+
+    // To complete the workflow, send the requests here out and call
+    // `machine.markRequestAsSent`.
+}
+
+main();
+```
+
+### With tracing (experimental)
+
+If you want to enable [tracing](https://tracing.rs), i.e. to get the
+logs, you should re-compile the extension with the `tracing` feature
+turned on:
+
+```sh
+$ npm run build -- --features tracing
+```
+
+Now, you can use the `MATRIX_LOG` environment variable to tweak the log filtering, such as:
+
+```sh
+$ MATRIX_LOG=debug npm run test
+```
+
+See
+[`tracing-subscriber`](https://tracing.rs/tracing_subscriber/index.html)
+to learn more about the `RUST_LOG`/`MATRIX_LOG` environment variable.
