Rating component

Datatype: "rating"

A row of stars, hearts, circles or custom icons filled to a value — with exact/half/rounded partial fills and an optional numeric label. Perfect for reviews and scores.

Rating examples

Real renders of the rating — each one is the same component with different property values, and the API payload below each preview reproduces it exactly.

App store rating badge

A 4.8-star average with the decimal score alongside, ready for a landing page.

API overrides for this example
{
  "score.value": 4.8,
  "score.showValue": true,
  "score.valueFormat": "decimal",
  "score.valueColor": "#374151"
}

Weekly CSAT report

The support team satisfaction average as green stars for a Monday Slack digest.

API overrides for this example
{
  "score.value": 4.2,
  "score.activeColor": "#10B981",
  "score.showValue": true,
  "score.valueFormat": "fraction",
  "score.valueColor": "#065F46"
}

All rating styles

Every style rendered live — each is just a different set of property values on the same component, and each has its own page with a dedicated preview, use cases and API example.

HeartsHeart icons — likes, favorites and health bars.
Half fill + labelFractional score rounded to halves with a "3.5/5" label alongside.
Outline emptyUnfilled icons render as outlines instead of solid gray.
EmojiAny emoji as the rating unit via the custom icon shape.
Ten-point scaleTen icons with a fractional "8.6/10" label — review scores out of ten.

Use cases

What developers typically build with the rating component.

  • Product OG images showing the live review average
  • Testimonial cards with the customer score rendered as stars
  • App store rating badges for marketing sites
  • Weekly CSAT report images for Slack or email

Use it dynamically via the API

Set '<key>.value' (or just '<key>') to the score for each render; max, colors and border props are overridable too.

Full API request with the sample design's current values — the playground above sends only the properties you change
curl --location 'https://render.imejis.io/v1/{{YOUR_DESIGN_ID}}' \
--header 'dma-api-key: {{YOUR_API_KEY}}' \
--header 'Content-Type: application/json' \
--data '{
    "score.value": 4,
    "score.max": 5,
    "score.iconShape": "star",
    "score.activeColor": "#FBBF24",
    "score.inactiveColor": "#E5E7EB",
    "score.emptyStyle": "filled",
    "score.partial": "exact",
    "score.showValue": false,
    "score.valueFormat": "decimal",
    "score.opacity": 1
}'

Only send the properties you want to change — everything else keeps its design value. See the API documentation for all languages.

Frequently Asked Questions

Yes — send '<key>.value' (or just the key) with any number, including fractions like 4.3; max, colors and other properties are overridable too.

The partial property controls the last icon: 'exact' fills it proportionally, 'half' rounds to halves and 'round' rounds to a whole icon.

iconShape supports star, heart, circle or custom — with customEmoji for any emoji or customPath for your own SVG path.

Enable showValue and pick a valueFormat — decimal (4.5), fraction (4.5/5) or countOfTotal ("4 of 5") — with valueColor for styling.
