+# foris-js
+Set of utils and common React elements for reForis.
+
+## Publishing package
+
+### Beta versions
+
+Each commit to `dev` branch will result in publishing a new version of library
+tagged `beta`. Versions names are based on commit SHA, e.g. 
+`foris@0.1.0-beta.d9073aa4`.
+
+### Preparing a release
+
+1. Crete a merge request to `dev` branch with version bumped
+2. When merging add `[skip ci]` to commit message to prevent publishing
+unnecessary version
+3. Create a merge request from `dev` to `master` branch
+4. New version should be published automatically
+
+## Manually managed dependencies
+Because of `<ForisForm />` component it's required to use exposed `ReactRouterDOM`
+object from `react-router-dom` library. `ReactRouterDOM` is exposed by
+[reForis](https://gitlab.labs.nic.cz/turris/reforis/reforis/blob/master/js/webpack.config.js).
+It can be done by following steps:
+ 
+1. Setting `react-router-dom` as `peerDependencies` and `devDependencies` in `package.json`.
+2. Adding the following rules to `externals` in `webpack.conf.js` of the plugin:
+
+```js
+externals: {
+    ...
+    "react-router-dom": "ReactRouterDOM",
+}
+```

+`<ForisForm/>` is Higher-Order Component which encapsulates entire form logic and provides with children required props.
+This component structure provides comfort API and allows to create typical Foris module forms easily.
+
+## Example of usage of `<ForisForm/>`
+You can pass more forms as children.
+```js
+<ForisForm
+    ws={ws}
+    forisConfig={{
+        endpoint: API_URLs.wan,
+        wsModule: "wan",
+    }}
+    prepData={prepData}
+    prepDataToSubmit={prepDataToSubmit}
+    validator={validator}
+>
+    <WANForm />
+    <WAN6Form />
+    <MACForm />
+</ForisForm>
+```
+
+### Example of children forms `props` usage
+
+```js
+export default function MACForm({
+    formData, formErrors, setFormValue, ...props
+}) {
+    const macSettings = formData.mac_settings;
+    const errors = (formErrors || {}).mac_settings || {};

+
+                onChange={setFormValue(
+                    (value) => ({ mac_settings: { custom_mac_enabled: { $set: value } } }),

+                : null}

+| `formErrors`   | object | Errors returned after validation via validator.                            |
+| `setFormValue` | func   | Function for data update. It takes update rule as arg (see example above). |
