Demos and Development

$3

The repo uses submodules. If you did not clone with --recursive then you need to call
`
git submodule update --init
`

The package manager used to install and link dependencies must be pnpm or yarn. npm wont work.

To develop and test:
if you use yarn then run yarn
if you use pnpm then run pnpm i

Interactive Menu:

To start the interactive menu, run npm start (or yarn start or pnpm start). This will list all of the commonly used scripts.

$3

`bash
npm run build.all
`
WARNING: it seems yarn build.all wont always work (not finding binaries in node_modules/.bin) which is why the doc explicitly uses npm run

$3

`bash
npm run demo.[ng|react|svelte|vue].[ios|android]

npm run demo.svelte.ios # Example
`

Demo setup is a bit special in the sense that if you want to modify/add demos you dont work directly in demo-[ng|react|svelte|vue]
Instead you work in demo-snippets/[ng|react|svelte|vue]
You can start from the install.ts of each flavor to see how to register new demos


[](#contributing)



Contributing

$3

You can update the repo files quite easily

First update the submodules

`bash
npm run update
`

Then commit the changes
Then update common files

`bash
npm run sync
`
Then you can run yarn|pnpm, commit changed files if any

$3


`bash
npm run readme
`

$3

`bash
npm run doc
`

$3

The publishing is completely handled by lerna (you can add -- --bump major to force a major release)
Simply run
`shell
npm run publish
`

$3

The repo uses https:// for submodules which means you won't be able to push directly into the submodules.
One easy solution is t modify ~/.gitconfig and add
`
[url "ssh://git@github.com/"]
pushInsteadOf = https://github.com/
