Mailbox Component

This feature is in Maintenance mode. Nylas will patch bugs and vulnerabilities but is not currently working on new functionality.

Use the Nylas Mailbox Component to connect to any inbox and provide a custom front end for your applications.

Without needing to write a single line of code, the Mailbox Component comes with:

  • To, from, subject display
  • Message previews
  • Thread display and expansion on click
  • Ability to star threads
  • Ability to mark threads as read or unread
  • Thread selection, including selecting all threads
  • Built-in pagination
  • Customization options

Quickstart

  1. Create a Mailbox component in your Nylas Dashboard.
  2. Add it to your application.
    <head>
      <!-- Import the script from CDN -->
      <script src="https://unpkg.com/@nylas/components-mailbox"></script>
    </head>
    <body>
      <!-- Place the component on the page -->
      <nylas-mailbox id="<PASTE_YOUR_COMPONENT_ID>"></nylas-mailbox>
    </body>

That’s It! Your Mailbox Component is ready to use!

Ways to Use the Mailbox Component

Use the Mailbox Component with Nylas Data

You'll learn how to use your Nylas accounts with the Mailbox Component.

Create the Mailbox Component

  1. Log in to your Nylas dashboard.
  2. Click Components > Mailbox
  3. Name your Component and select the account. To quickly start testing your Component select Enable for a single account.
    1. To learn how to enable components for multiple accounts see Authorizing Components
  4. Use an existing access token or generate a new one.
  5. Enter the domain the component will run on. Without the domain, the component will not run.
    1. To run on localhost, enter an asterisk. *. Remember to change this before going to production.
  6. Save your new component.
  7. On the Edit page, you can configure your component behavior and appearance.

Generate an Access Token

Generating a new access token will not replace your existing access token; it will create a second access token with the same scopes as the previous token. You can revoke access tokens at any time.

Add the Component To Your Application

  1. On the Edit page, there are instructions for installing the new component.
    1. We recommend that you filter or query your threads. Mailbox will display threads located in inbox and trash.
    2. Search will accept any keyword and filter accepts any query parameter listed for Threads.
  2. If you haven't installed the Mailbox Component already, open a terminal and run npm i @nylas/components-mailbox.
  3. Then add your Nylas component. Copy and paste your component code into your application.
    <nylas-mailbox id="your-component-id" ></nylas-mailbox>
  4. You should refresh your application if needed. Any configuration options set on the editing page will apply to your Component.

Use the Mailbox Component with External Data

You can pass your own thread data for Mailbox to display. The threads format and type need to match the Threads object.

Authorizing Components

You can authorize components to work with a single account or multiple accounts.

Enable for a single account

Enabling components for a single account is a good way to get started quickly. If you use this method in your production application, you must authenticate each account from the Nylas Dashboard one-by-one.

Enable components single account

Enable for all accounts

🔍 Dashboard previews don't work when you enable components for all accounts.

To enable components for all accounts, you must pass in an end user's access token as a property of the component. One way to do this is to create a login screen, capture the access token, and pass it to the component. You can pass access_tokens directly in the component, as in the following example.

<nylas-agenda id="COMPONENT-ID" access_token="USER-ACCESS-TOKEN"/>

Be sure to keep your end users' access tokens hidden, and never expose them online.

Enable Components for all accounts

Administrator Requirements

The Mailbox Component requires administrative privileges in order to authorize all accounts from the dashboard. Non-administrative users can only authorize a single account.

Customization

Nylas Components are flexible and can be customized for your needs.

Use event listeners to customize the mailbox.

Custom CSS

To customize the CSS, you can change the theme custom property to one of the provided themes by Nylas:

    <nylas-mailbox id="NYLAS_MAILBOX_COMPONENT_ID" theme="light"></nylas-mailbox>

You can also easily override styles for pre-selected themes by writing your own CSS vars. The customizable CSS variables for Mailbox Component are the following and the value assigned should be a valid CSS property value:

    .nylas-mailbox {
      /* Mailbox variables */
      --nylas-mailbox-font-family: sans-serif;
      --nylas-mailbox-border-color: #e1e1e1;
      --nylas-mailbox-vertical-border-color: #e1e1e1;
      --nylas-mailbox-horizontal-border-color: #e1e1e1;
      --nylas-mailbox-hover-shadow-color: #cacaca;

      --nylas-mailbox-header-background: #fff;
      --nylas-mailbox-toolbar-background: #fff;
      --nylas-mailbox-read-background: #f5f5f5;
      --nylas-mailbox-unread-background: #fff;
      --nylas-mailbox-checked-border-color: #4169e1;
      --nylas-mailbox-checked-bg-color: #e0e6f9;
      --nylas-mailbox-checkedbox-active-color: #4169e1;

      --nylas-mailbox-pagination-button-color: #4b4b4b;
      --nylas-mailbox-pagination-button-background: #fbfcfe;
      --nylas-mailbox-pagination-button-background-disabled: #eaeaea;
      --nylas-mailbox-pagination-button-border-color: #eaeaea;
      --nylas-mailbox-pagination-button-hover-color: #eaeaea;
      --nylas-mailbox-pagination-indicator-color: #2c2c2c;
    }

You can also provide your own stylesheet to the theme custom property. Review the light.css theme to get the CSS variable names:

    <nylas-mailbox 
      id="NYLAS_MAILBOX_COMPONENT_ID"
      show_header="false"
      theme="https://example.com/my-mailbox-theme.css"
    ></nylas-mailbox>

Allowed Domains

You can restrict the domains that your component works on using glob patterns, as in the following examples:

  • nylas.com matches only nylas.com.
  • subdomain.nylas.com matches only subdomain.nylas.com.
  • *subdomain.nylas.com matches subdomain.nylas.com and sub.sub.subdomain.nylas.com.
  • * matches any domain.

Domain restriction applies only to the domain name. You cannot restrict URL paths (for example, developer.nylas.com/docs/) or protocols (for example, HTTPS).

How Properties Are Handled

Nylas Components follow an order of operations to decide if the dashboard or code takes precedence.

  1. If the property is passed directly to the Component, use that first.
  2. If the property is not passed directly in the Component, use the dashboard settings.
  3. If there are no properties set in the Component or the dashboard, use the Component defaults.
