# react-admin-lolo

A Library for schema-driven web apps using [Lolo](https://lolo.company), [React Admin](https://github.com/marmelab/react-admin) and [RJSF](https://github.com/rjsf-team/react-jsonschema-form) at core.

From **Create, Read, Update, Delete** operations to more complex implementations such as Graphs, Autocomplete widgets and Map Integrations are **schema driven**.

That is, _As Schema changes, the View, Components, Widgets change and operate accordingly._

## Installation

Create a new React app using custom configurations or create-react-app

```
npx create-react-app my-example-app
```

react-admin-lolo is available via npm as [Lolo](https://lolo.company) Org scoped publicly available package. You can install it using:

```
npm install --save @lolocompany/react-admin-lolo
```

### Note:

react-admin-lolo requires a few dependencies to be installed along with it to operate as expected.

- @aws-amplify/ui-react: ^1.2.5
- aws-amplify: >=3.0.0
- react-admin: >=3.0.0
- react-admin-import-csv: >=1.0.0

```
npm install --save @aws-amplify/ui-react@1.2.5 aws-amplify react-admin react-admin-import-csv
```

## Documentation

### Implementation

To generate base Layout, Menu, AppBar and Dashboard view out of the box, include the following code in your React App, `App.js` file.

```javascript
// in App.js

import React from 'react';
import { LoloAdmin, LoloResource } from '@lolocompany/react-admin-lolo';

function App() {
  return (
    <LoloAdmin
      apiUrl={"https://dev.lolo.company/" + AppId}
      title="My app"
    >
      <LoloResource name="directors" />
      <LoloResource name="movies" />
    </LoloAdmin>
  );
}

export default App;
```

### Customizing

#### Override Props

LoloResource supports the same override props as react-admin [Resource](https://marmelab.com/react-admin/Resource.html#the-resource-component). So for example, to customize the side menu icon and list view for directors:

```javascript
import UserIcon from '@material-ui/icons/People';
import MyList from './MyList';

<LoloResource name="directors" icon={UserIcon} list={MyList} />;
```

#### Schema Transforms

Schema transform functions help you manipulate the schema that is fetched from the respective resource's schema API. Each function recieves following values as arguments `transform(writableSchema, pristineSchema, selectedAccount)` where in:

- `writableSchema`: Manipulated schema with updated/removed properties

- `pristineSchema`: Original schema recieved from the resource's schema API

- `selectedAccount`: Current account selected for the panel

The `LoloResource` component accepts the following schema tranform functions as props:

- `listSchemaTransform`: Manipulates the `List` component schema. It helps in displaying selected fields on the table list. For Example, the following will only display _ID_ and _Name_ on the enterprise table:

```javascript
<LoloResource
  name="enterprises"
  listSchemaTransform={({ properties, ...rest }, pristineSchema, selectedAccount) => {
    const { id, name } = properties;
    return {
      ...rest,
      properties: { id, name },
    };
  }}
/>
```

- `createSchemaTransform`: Manipulates the `Create` component schema. For Example, the following will add an extra field _customId_ on the create form with a read only property:

```javascript
<LoloResource
  createSchemaTransform={(writableSchema, pristineSchema, selectedAccount) => ({
    ...writableSchema,
    customId: { type: 'string', readOnly: true },
  })}
/>
```

- `editSchemaTransform`: Manipulates the `Edit` component schema. For Example, the following will add an extra field _customId_ on the edit form:

```javascript
<LoloResource
  editSchemaTransform={(writableSchema, pristineSchema, selectedAccount) => ({
    ...writableSchema,
    customId: { type: 'string' },
  })}
/>
```
