Layer Financial React Components

Layer's embeddable React component library provides an out of the box accounting experience. This project emphasizes composability and brandability, allowing you to

1. Use full page layouts we've already tested and used or layout individual components however you choose.
2. Brand components with your company colors, fonts, and more.

All you need to get started is sandbox development credentials - reach out here if you don't have those yet!

Installation

npm install --save @layerfi/components

or

yarn install @layerfi/components

Usage

Nest the components you want to use under the LayerProvider component. You should provide the component with a few props:

• businessId The ID of the business whose information you're showing.
• businessAccessToken Temporary authentication token scoped to this specific business. See the getting started guide for how to fetch these tokens on your backend.
• environment (Optional, defaults to "production") the Layer environment you're attempting to access [staging or production]
• theme (Optional) to customize the look of components
• onError (Optional) to get notified about exceptions

import { LayerProvider } from "@layerfi/components";
...
<LayerProvider
  businesId="..."
  businessAccessToken="..."
  environment={'staging'}
>
  {...}
</LayerProvider>

Development

In development, it's often convenient to avoid fetching business-scoped tokens. You may find it more convenient to set your sandbox clientId and clientSecret directly, which will give you access to any business in your sandbox account.

import { LayerProvider } from "@layerfi/components";
...
<LayerProvider
  businesId="..."
  appId="..."
  appSecret="..."
  environment={'staging'}
>
  {...}
</LayerProvider>

Components

Bank Accounts & Transactions

Linked Accounts

Displays all accounts connected to Layer including embedded banking, Plaid, and custom accounts.

<LinkedAccounts
  elevated={elevatedLinkedAccounts}
  showLedgerBalance={showLedgerBalance}
/>

Props:

• asWidget: Minimized version of the component
• elevated: Stylistic option to highlight component
• showLedgerBalance: Flag to enable or hide the current ledger balance corresponding to this external account. Useful for reconciliation.

Transaction categorization

The transaction categorization component handles displaying both categorized transactions and the workflow for categorizing new transactions as they are imported into Layer.

<BankTransactions asWidget />

Optional properties and useBankTransactionsContext give more control over the transactions list:

/** Using props */
<BankTransactions
  filters={{
    amount: { min: 0, max: 100 },
  }}
/>

/** Using hook */
const { setFilters } = useBankTransactionsContext()

setFilters({ amount: { min: 0, max: 10000 } })

<BankTransactions />

Reporting

Profit And Loss Chart

import { ProfitAndLoss } from "@layerfi/components";
…
<ProfitAndLoss>
  <ProfitAndLoss.Chart />
  <ProfitAndLoss.Summaries />
  <ProfitAndLoss.DatePicker />
  <ProfitAndLoss.Table />
</ProfitAndLoss>

Profit and Loss Summaries

import { ProfitAndLoss } from "@layerfi/components";
…
<ProfitAndLoss>
  <ProfitAndLoss.Summaries />
</ProfitAndLoss>

The P&L Summaries section supports several optional props:

• actionable: When enabled, clicking the revenue & expense charts will open the P&L sidebar view.
• variants: Override the size of the component; supports a small and large version.

Profit and Loss Table

import { ProfitAndLoss } from "@layerfi/components";
…
<ProfitAndLoss>
  <ProfitAndLoss.Table>
</ProfitAndLoss>

The P&L table supports one optional prop:

• lockExpanded forces the table to be fully expanded showing all rows

Balance Sheet

The Balance Sheet component displays an interactive table. A default date can be passed in via the effectiveDate prop.

Statement of Cash Flows

The statement of cashflows component is an interactive table displaying cash changes broken out into investing, financing, and operational activities. It is shown calculated via the standard indirect method.

Ledger

Chart of Accounts

The chart of accounts gives direct read-and-write access into the double-entry general ledger underlying Layer's data. It exposes the list of accounts and enables users to create new accounts.

<ChartOfAccounts asWidget withDateControl withExpandAllButton />

The following props are supported

• asWidget: Displays a more compact version.
• withDateControl: Includes a date picker that determines the effective date of account balances displayed.
• withExpandAllButton: Optionally displays a button to expand and collapse all sub-account lists.

Journal

The Journal component displays the full history of journal entries and allows users to create journal entries by hand as well.

A sidebar expands to display details about the invoice.

<Journal />

The follow props are supported:

• asWidget: Compact version

Styling

You have a range of options for custom styling. In order of most simple to most control:

1. Using the theme attribute of LayerProvider,
2. Setting CSS variables,
3. Overwriting CSS classes.

Using theme attribute

The theme attribute allows you to set primary light and dark colors. The component will then use your primary colors to create a cohesive color palette across all components. We won't add any new colors, just different lightness of your brand colors for accents where helpful, e.g. hover states.

<LayerProvider
  businessId="..."
  environment="..."
  theme={{
    colors: {
      // Base colors:
      dark: { h: '28', s: '26%', l: '11%' },
      light: { h: '52', s: '100%', l: '55%' },
    },
  }}
>
  {...}
</LayerProvider>

The colors can be defined in HSL, RGB or HEX:

// HSL:
colors: {
  dark: { h: '28', s: '26%', l: '11%' },
  light: { h: '52', s: '100%', l: '55%' },
},

// RGB:
colors: {
  dark: { r: '36', g: '28', b: '21' },
  light: { r: '255', g: '224', b: '27' },
},

// HEX:
colors: {
  dark: { hex: '#241C15' },
  light: { hex: '#FFE01B' },
},

CSS variables

body .Layer__component {
  --color-dark-h: 167;
  --color-dark-s: 38%;
  --color-dark-l: 15%;

  --text-color-primary: #333;

CSS classes

For fine grained control, you can override specific classes. We recommend using your browser dev tools to find the component you want to restyle and override that specific class with a higher priority CSS rule.

body .Layer__table-cell-content {
  background: white;
}

body .Layer__bank-transaction-row .Layer__table-cell-content {
  background: gray;
}

Error callback

Use onError property on <LayerProvider /> to get notified about all exceptions:

<LayerProvider
  businessId="..."
  environment="..."
  appId="..."
  onError={err => console.log('My error callback', err)}
>
  {...}
</LayerProvider>

...or on the specific component:

<BankTransactions onError={e => console.log('My callback:', e)} />
