So I have this node/mongodb app with this function:
const myFuncDoesALotOfThings = async () => {
try{
await CollectionA.deleteMany({});
await CollectionB.deleteMany({});
const allCollectionsC = CollectionsC.find({'country': "UK"});
for await (const coll of allCollectionsC){
if(coll.city === 'London'){
await doSomeMongoDbOperation();
}
}
}
catch(exception){
console.log("exception",exception);
//here I think I want to resume
}
}
My concern is about the failure of await doSomeMongoDbOperation();
.
How can I make sure that exception on one single await doSomeMongoDbOperation();
will not stop the iteration?
wrap another try catch around your api so it won't stop the iteration.
const myFuncDoesALotOfThings = async () => {
try{
await CollectionA.deleteMany({});
await CollectionB.deleteMany({});
const allCollectionsC = CollectionsC.find({'country': "UK"});
for await (const coll of allCollectionsC){
if(coll.city === 'London'){
try{
await doSomeMongoDbOperation();
} catch(e){
console.log("mongo operation failed")
}
}
}
}
catch(exception){
console.log("exception",exception);
//here I think I want to resume
}
}
