Twemoji is a library that provides standard Unicode emoji support across all platforms.
The library solves the problem of inconsistent emoji rendering by offering a unified set of emoji assets that work consistently regardless of the user's operating system or browser. It works by parsing HTML content or strings to identify emoji characters and replacing them with standardized image assets. The tool supports all Unicode-defined emoji recommended for general interchange and adheres to the Unicode and Emoji specifications. It offers both DOM parsing, which is recommended for security as it avoids innerHTML and only modifies text nodes, and string parsing for legacy use cases.
Developers should choose this tool if they need consistent emoji rendering across platforms and want to avoid relying on system-level emoji support that may vary by device. It suits projects where visual consistency of emoji is important and where custom emoji are not required. The library can be included via CDN for always-using the latest version, or downloaded for specific versions. Adopters should be aware that the tool does not support custom emoji and that string parsing is not recommended due to security concerns around sanitization.
The project maintains a substantial base of adopters who report issues from real-world use rather than the core team driving the issue agenda. Maintainers typically respond to new issues and pull requests within a few days. Work in the issue tracker is dominated by user questions.
