README

LajiForm is a dynamic form built on React. It can be used as a standalone library or as a React component. LajiForm is a wrapper for react-jsonschema-form.

Installing

npm install laji-form --save

If you are going to use the bootstrap 3 theme, you need to install also react-bootstrap:

npm install react-bootstrap@0.33.1 --save

Usage as a library

LajiForm passes all its properties to react-jsonschema-form. Read the documentation for react-jsonschema-form.

Usage as a standalone library

import LajiForm from "laji-form";

new LajiForm({
  schema: schema,
  uiSchema: uiSchema, formData: formData,
  rootElem: document.getElementById("app")
});

You can update the properties with setState(props). You need to pass only the properties that you are changing, since it just calls the React component's setState(props).

You can unmount the component with unmount().

Usage as a React component

import React from "react";
import { render } from "react-dom";
import LajiForm from "laji-form/lib/components/LajiForm";

render(<LajiForm
    schema={...}
    uiSchema={...}
    formData={...} />,
  document.getElementById("app"));

API Client

In addition to properties you would pass to <Form />, you must pass an api client implementation, if you need to use fields that use lajitest.api.fi. The api client implementation must have fetch() -method, which returns a Promise.

fetch(path, query, options) parameters are as follows:

• path: URL path for GET.
• query: Object, where keys are param names and values are param values.
• options: Object containing options for request.

See the example implementation in src/playground/ApiClientImplementation.js.

Pass the implementation to LajiForm like so:

<LajiForm apiClient={new ApiClientImplementation()} ... />

Themes

LajiForm provides bootstrap 3 theme. To use it, you need to install react-bootstrap@0.33.1 and provide the built-in bootstrap 3 theme it as a prop:

import bs3 from "laji-form/lib/themes/bs3";

<LajiForm theme={bs3} ... />

You can also use a custom theme and provide it the same way. There is a theme interface themes/theme.ts which the theme must implement.

Notifications

LajiForm expects a notification implementation as a paratemer notifier. The notifier object must implement the interface below:

{
    success: message => (),
    warning: message => (),
    info: message => (),
    error: message => (),
}

Styles

Styles can be found at dist/styles.css.

Development

Run npm ci to install the dependencies and npm start to start the app.

Before running, you'll need to configure your personal apitest.laji.fi access token. Get the key to your email:

curl -X POST --header "Content-Type: application/json" --header "Accept: application/json" -d "{\
  \"email\": \"<YOUR EMAIL ADDRESS>\"\
  }" "http://apitest.laji.fi/v0/api-token"

Copy settings template file:

cp properties.json.example properties.json

Then put the API access token you got in your email to properties.json. Put also your user access token & user ID there. Google API key is needed only for using the reverse geo location for foreign locations.

Try to keep the code style consistent - npm run lint should pass without errors.

Developing different forms

Start the server and navigate to the local playground http://localhost:8083?id={form_id}

Playground query parameters

Option	Default	Description
id	-	Form id to use. If empty, playground/schemas.json will be used for form schemas.
local	false	Use local schemas under forms/ instead of fetching from apitest.laji.fi.
localFormData	false	Use local formData under forms/${id}.formData.json instead of form's prepopulatedDocument.
settings	true	Use local settings defined in playground/schemas.
lang	fi	Language of the form. Doesn't affect local forms.
readonly	false	Sets the form readonly.

Examples

http://localhost:8083?id=JX.519 Trip report form with empty formData.

http://localhost:8083?id=MHL.1&localFormData=true Line transect form with local formData.

Tests

You need to update the webdriver before testing:

webdriver-manager update

The playground server must be running before running the tests.

Run the tests with npm test.

Test parameters

Parameters are given as envirnment variables, i.e. TEST_BROWSER=chrome npm test

Option	Default	Description
TEST_BROWSER	-	chrome or firefox. Tests are run for both by default.
HEADLESS	true	Run the tests in a visible browser window if true.
THREADS	4	How many browser instances to use for parallel testing.
