🚧 cardano-wallet-tx package

Archived, in favor of Lucid

Allows creating transactions based on configuration, including minting and plutus scripts

It uses npm, TypeScript compiler, Jest, webpack, ESLint, Prettier, husky, pinst, commitlint. The production files include CommonJS, ES Modules, UMD version and TypeScript declaration files.

For Cardano related operations it uses custom version of cardano serialization library and CardanoKoios or Graphql instance to for chain data.

Development

Set up tools and environment

You need to have Node.js installed. Node includes npm as its default package manager.

Open the whole package folder with a good code editor, preferably Visual Studio Code. Consider installing VS Code extensions ES Lint and Prettier.

In the VS Code top menu: Terminal -> New Terminal

Install dependencies

Install dependencies with npm:

npm i

Build

Build production (distribution) files in your dist folder:

npm run build

It generates CommonJS (in dist/cjs folder), ES Modules (in dist/esm folder), bundled and minified UMD (in dist/umd folder), as well as TypeScript declaration files (in dist/types folder).

Try it before publishing

Run:

npm link

npm link will create a symlink in the global folder, which may be {prefix}/lib/node_modules/example-typescript-package or C:\Users<username>\AppData\Roaming\npm\node_modules\example-typescript-package.

Create an empty folder elsewhere, you don't even need to npm init (to generate package.json). Open the folder with VS Code, open a terminal and just run:

npm link example-typescript-package

This will create a symbolic link from globally-installed example-typescript-package to node_modules/ of the current folder.

You can then create a, for example, testnum.ts file with the content:

import { Num } from 'example-typescript-package'
console.log(new Num(5).add(new Num(6)).val() === 11)

If you don't see any linting errors in VS Code, if you put your mouse cursor over Num and see its type, then it's all good.

Whenever you want to uninstall the globally-installed example-typescript-package and remove the symlink in the global folder, run:

npm uninstall example-typescript-package -g

Prepare to publish

Create an npm account.

Manual publishing to npm

Log in:

npm adduser

And publish:

npm publish

This package is configured to use GitHub Actions CI/CD to automate both the npm and GitHub Packages publishing process. The following are what you have to do.

CI publishing to npm

Follow npm's official instruction to create an npm token. Choose "Publish" from the website, or use npm token create without argument with the CLI.

If you use 2FA, then make sure it's enabled for authorization only instead of authorization and publishing (Edit Profile -> Modify 2FA).

On the page of your newly created or existing GitHub repo, click Settings -> Secrets -> New repository secret, the Name should be NPM_TOKEN and the Value should be your npm token.

CI publishing to GitHub Packages

The default configuration of this example package assumes you publish package with an unscoped name to npm. GitHub Packages must be named with a scope name such as "@ADAOCommunity/example-typescript-package".

Change scope: '@ADAOCommunity' to your own scope in .github/workflows/publish.yml, also change addscope in package.json.

If you publish package with a scoped name to npm, change the name to something like "@ADAOCommunity/example-typescript-package" in package.json, and remove the - run: npm run addscope line in .github/workflows/publish.yml

If you publish your package to npm only, and don't want to publish to GitHub Packages, then delete the lines from - name: Setup .npmrc file to publish to GitHub Packages to the end of the file in .github/workflows/publish.yml.

(You might have noticed secret.GITHUB_TOKEN in .github/workflows/publish.yml. You don't need to set up a secret named GITHUB_TOKEN actually, it is automatically created)

Publish

Now everything is set. The example package has automated tests and upload (publishing) already set up with GitHub Actions:

• Every time you git push or a pull request is submitted on your master or main branch, the package is automatically tested against the desired OS and Node.js versions with GitHub Actions.
• Every time an annotated (not lightweight) "v*" tag is pushed onto GitHub, a GitHub release is automatically generated from this version, it also automatically publishes to the npm registry and/or GitHub Packages registry to update the package there.
  • npm version / yarn version is useful to create tags.
  • (npm or yarn v1, not yarn v2) You could also add "postversion": "git push --follow-tags" to package.json file to push it automatically after npm or yarn version.
  • (yarn v1, not v2) because yarn version doesn't check whether there are uncommitted changes, you can add "preversion": "git diff-index --quiet HEAD --" to package.json
    • Note: preversion, postversion doesn't work in yarn v2

For npm registry: you can unpublish a version or the whole package but can never re-publish the same version under the same name.

If you want to modify the description / README on the npm package page, you have to publish a new version. You can modify the description on GitHub Packages without publishing.

Notes

• It uses npm but you can easily switch to yarn, of course (remember to change all "npm" in scripts in the file package.json)
  • Whether you use npm as your package manager ≠ Whether you can publish to the npm registry
• Works fine in VS Code. In my configuration .eslintrc and .prettierrc cooperate perfectly
• See scripts in package.json for other predefined script commands
• pinst is used to solve a problem of husky
• The installation of the package with npm, yarn v1 and yarn v2+ is ensured in this test
