I have global variable result_crnt. I try to update it inside of consumerRun function:
global.result_crnt = '';
async function consumerRun(){
try{
await consumer.run({
eachMessage: async({ topic, partition, message }) => {
console.log({
topic: topic,
partition: partition,
message: message.value.toString(),
})
result_crnt = message.value.toString();
}
})
}catch (error){
console.log('ERROR: ', error);
}
}
When I try to send a response using this variable (result_crnt):
api.get("/test/req", async function(req, res){
consumerRun();
while(true){
if (result_crnt != '') break;
}
res.status(200).json({"result_crnt": result_crnt});
})
But it stuck inside while block, and result_crnt doesn't seem to update, even though I get the message inside run (I can see output in console). What am I doing wrong? How can I fix it?
