To illustrate how bad kind0 is sometimes below is a real function I wrote (unfortunately) like 2 years ago to get users fields from their profile:
export const findKind0Fields = async kind0 => {
let fields = {};
const usernameProperties = ['name', 'displayName', 'display_name', 'username', 'handle', 'alias'];
const pubkeyProperties = ['pubkey', 'npub', '_pubkey'];
const findTruthyPropertyValue = (object, properties) => {
for (const property of properties) {
if (object?.[property]) {
return object[property];
}
}
return null;
};
const username = findTruthyPropertyValue(kind0, usernameProperties);
if (username) {
fields.username = username;
}
const avatar = findTruthyPropertyValue(kind0, [
'picture',
'avatar',
'profilePicture',
'profile_picture',
'image',
]);
if (avatar) {
fields.avatar = avatar;
}
const pubkey = findTruthyPropertyValue(kind0, pubkeyProperties);
if (pubkey) {
fields.pubkey = pubkey;
}
const lud16 = findTruthyPropertyValue(kind0, ['lud16', 'lightning', 'lnurl', 'lnurlp', 'lnurlw']);
if (lud16) {
fields.lud16 = lud16;
}
const nip05 = findTruthyPropertyValue(kind0, ['nip05']);
if (nip05) {
fields.nip05 = nip05;
}
return fields;
};
