Readme
cardano-addresses TypeScript binding
This is a Typescript (or Javascript) version of the
cardano-addresses
API.
For the time being, this module is experimental, and exposes only a subset of the functionality of the Haskell API. We would like to increase the TypeScript binding's coverage of the Haskell API in future, as needs arise.
How it works
This package comprises of four parts:
A GHCJS build of the
cardano-addresses
library.An emscripten build of the libsodium crypto library, supported by the
cardano-addresses-jsbits
package.A Cabal package
cardano-addresses-jsapi
containing GHCJS foreign exports for translating Javascript function calls and values into Haskell function calls and values, and vice-versa.An NPM package
cardano-addresses
containing both CommonJS and EcmaScript modules written in TypeScript, which thinly wraps the GHCJS foreign exports in order to make a proper API.
Development Info
NodeJS module: Building and testing
Start a nix-shell
in this directory (not the top-level) and run:
$ cd jsapi
$ nix-shell
[nix-shell:~/iohk/cardano-addresses/jsapi]$ npm install && npm run build
...
[nix-shell:~/iohk/cardano-addresses/jsapi]$ npm run test
Behind the scenes, this will use Nix to make the ghcjs
build of the cardano-addresses
library. The path to this Javascript file is stored in the $CARDANO_ADDRESSES_JS
environment variable.
Haskell module: Building and testing
To try it out run nix-shell
from the repo top-level directory:
$ nix-shell
[nix-shell:~/iohk/cardano-addresses]$ js-unknown-ghcjs-cabal build cardano-addresses-jsapi:jsapi-test
[nix-shell:~/iohk/cardano-addresses]$ node dist-newstyle/build/js-ghcjs/ghcjs-8.10.4/cardano-addresses-jsapi-3.5.0/t/jsapi-test/build/jsapi-test/jsapi-test.jsexe/all.js
That test initializes the api from a JS function that is called from Main.hs
. To build .js
file that might be easier to use from a JS app run:
$ nix-build jsapi/default.nix -A cardano-addresses-js
/nix/store/dw0xwvjvwac68i2a4dkkpx4mw8yji9z8-cardano-addresses-js-3.5.0
$ tree ./result
./result
├── cardano-addresses-jsapi.cjs.js
└── cardano-addresses-jsapi.js
This replaces the regular runmain.js
with jsapi/glue/runmain.js
. That exposes a single function you can call and pass in a continuation.
To initialize, call the runCardanoAddressesApi
with a continuation that like the one in jsapi/glue/test.js
. You will be passed api
and cleanup
.
TODO
- [ ] More API endpoints depending on user needs.
- [ ] Used "typed" objects as parameters for the
inspectAddress
API, instead of strings which must be parsed. - [ ] Add a build step to optimise output file sizes (i.e. minification, tree shaking, etc).
- [ ] Solve issue on
nodejs
where registered event handlers remain after API cleanup, preventing thenodejs
runtime from exiting. - [ ] Add helper functions to the JSaddle API so that it can output code for ES6 Promises.
- [ ] Bring back headless testing of JSaddle code.
- [ ] Replace TSDX with a better build system.
- [ ] Automatically update docs in CI.
- [ ] Add release workflow to CI which builds the package and uploads to NPM.
More details
NodeJS package
For better or worse, this is based on the TSDX template. The TSDX standard documentation follows...
Commands
To run TSDX, use:
npm start # or yarn start
This builds to /dist
and runs the project in watch mode so any edits you save inside src
causes a rebuild to /dist
.
To do a one-off build, use npm run build
or yarn build
.
To run tests, use npm test
or yarn test
.
Configuration
Code quality is set up for you with prettier
, and lint-staged
. Adjust the respective fields in package.json
accordingly.
Jest
Jest tests are set up to run with npm test
or yarn test
.
Bundle Analysis
size-limit
is set up to calculate the real cost of your library with npm run size
and visualize the bundle with npm run analyze
.
Rollup
TSDX uses Rollup as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.
TypeScript
tsconfig.json
is set up to interpret dom
and esnext
types, as well as react
for jsx
. Adjust according to your needs.
Continuous Integration
GitHub Actions
Two actions are added by default:
tsdx-build
which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrixtsdx-size
which comments cost comparison of your library on every pull request usingsize-limit
Optimizations
Please see the main tsdx
optimizations docs. In particular, know that you can take advantage of development-only optimizations:
// ./types/index.d.ts
declare var __DEV__: boolean;
// inside your code...
if (__DEV__) {
console.log('foo');
}
You can also choose to install and use invariant and warning functions.
Module Formats
CJS, ESModules, and UMD module formats are supported.
The appropriate paths are configured in package.json
and dist/index.js
accordingly. Please report if any issues are found.
Publishing to NPM
TSDX recommend using np.
