# Parse Message

use the 'messageParse()' method to parse an original message

```javascript
import { messageParser } from "@relationlabs/im"

const msg: Message

const parsedMsg: ParsedMessage = messageParser(msg)
```

// to define types

```javascript
// message type
type MessageType = 'SYS' | 'TEXT' | 'CARD' | 'ANNOUNCEMENT' | 'BATCH_TRANSFER';

// the construct of an original message
type Message = {
    type: MessageType;
    content: string;
    quote?: Message;
}

// the construct generated by parsing a message
type ParsedMessage = {
    type: MessageType;
    content: string;
    parsedContent?: ParsedContent;
    quote?: Message;
    unidentified?: boolean | undefined;
}

//content parsed
type ParsedContent = string|JoinGroupMessage|ShareMessage|NormalImageMessage|NFTMessage|MentionMessage

// invitation to join a chat group
type JoinGroupMessage = {
    groupId: string;
    groupName: string;
    chatType: 'p2p'|'group'
}

// sharing an URL
type ShareMessage = {
    shareUrl: string;
    shareName: string;
    shareIcon: string;
}

// normal image
type NormalImageMessage = {
    imgUrl: string;
    s3Key: string;
}

// NFT
type NFTMessage = {
    imgUrl: string;
    nftChain: string;
}

// to quote a message
type MentionMessage = {
    mentionContent: string;
    mentionPosition: number[];
}
```

In `ParsedMessage` construct, `unidentified` flags if the message can be parsed, and `parsedContent` is the result parsed from the content in the original message. Other keys in the construct come from respective segments in the construct of the original message.
