Tip
This rule is included into the lingui/recommended config
Doesn't allow single variables without text to translate like <Trans>{variable}</Trans> or t`${variable}`
Such expression would pollute message catalog with useless string which has nothing to translate.
Examples of invalid code with this rule:
// invalid ⛔️
;<Trans>{user}</Trans>
t`${user}`
msg`${user}`Examples of valid code with this rule:
// valid ✅
;<Trans>Hello {user}</Trans>
t`Hello ${user}`
msg`Hello ${user}`
