asyncapi-rust-ws-template v0.3.2
asyncapi-rust-ws-template
npm project that converts AsyncAPI into rust websocket client crate
how it works
- exchange name is provided
- goes through each doc -> server -> channel, each serving as a websocket stream
- goes through each channel's send/receive operation, map their messages and payloads as stream input/output
- union payload gets converted as enum
- gets rendered with string operations
how to run terminal command
npm build, local YAML
$ asyncapi generate fromTemplate ASYNCAPI_DIR asyncapi-rust-ws-template -p exchange=EXCHANGE_NAME -o OUTOUT_DIRlocal build, local YAML (at the root of this project)
$ ag ASYNCAPI_DIR ./ -o OUTPUT_DIR template input requirement (AsyncAPI)
| spec | requirement |
|---|---|
| format | AsyncAPI v3 (pls check notes for its reason) |
| point of view | client (send request, receive reponse) |
| minimum content requirement for WS client | info, servers, channels, components , can be tested with -p validate=true |
template parameters
| parameter | options | description |
|---|---|---|
validate | true false (default) | to validate if a AsyncAPI has minimum content for generating websocket client |
render | true false (default) | to render a rust websocket client |
framework | tokio-tungstenite (default), async-tungstenite | rust websocket client framework to render |
template output (rust client crate)
The rust code generated by this template has the following structure
Cargo.toml// using infoREADME.md// using infosrc/lib.rs// overall libraryclient/mod.rs${client}.rs// using servers, channels, operations
model/mod.rs${message}.rs// using message schema with modelina
dev setup installation

| name | description |
|---|---|
| src/ | TypeScript ESM source code, transpiles into template directory |
| src/index.ts | transpiles to main template entry template/index.js, exposing the function for asyncapi generator command |
| hooks/ | AsyncAPI hooks for pre-process and post-process that cannot be derived by AsyncAPI (in CommonJS) |
| template/ | Javascript transcribed source code for template |
| test/input | local test input, AsyncAPI document |
| test/output | local test output, rust client crate (git-ignore) |
| package.json | NPM package definition, defines template configs |
| tsconfig.json | TypeScript transpile definition, defined transcribed datas |

design
- renderer:
- react rather than nunjucks, for its versatility. details here
- TypeScript, ESM (except hooks)
- generated code are derived as below:
- client (server)
- client function (channel)
- client function logic (operation)
- client function struct (schema)
- client code functionality:
- case 1: subscribe
- case 2: publish, subscribe
TODO
changelog: please check here
- design codegen structure
- study nunjucks vs react (decided to use react)
- code generation
- define code structure
- websocket client function from
operation - pubsub function from
channel - fix modelina referencing other model as
crate::*;
- code testing
- add unit test
- make server name configurable
- loads server name into unit test
- support N messages on an operation
- check for cases when one channel supports multiple inputs
- support for
async-tungstenite
recruitment
TypeScript AsyncAPI Template Developer
I am not a TS expert, so I would love to have an expert to accelarate development for websocket genrator in the following output languages:
typescript,go,python
notes
- changelog here
- support AsyncAPI V3 only because official v2 and v3 terminology on AsyncAPI are flipped.
- v2 calls operations "publish", "subscribe" from client's perspective
- v3 calls operations "receive", "send" from server's perspective
- this is objectively confusing, so make sure the input is an AsyncAPI V3 on client's perspective, which follows "send request, receive response"
