Say goodbye Trycatch Hell |

Say goodbye Trycatch HellHi everyone It is possible that it is here for the post title and I daresay you have had problems handling errors with async await In this post you will learn a trick to avoid trycatch hell but before it is neccessary to know a little history History of Callback Once upon a time developers had to deal with tasks that took a while and the way we could check if the task was done was through callback Callbacks are nothing more than functions that are executed when a task has been completed either erroneously or successfully Until this moment there is nothing bad The problem arises when these callbacks in turn execute other functions and so on And that s when the macabre happens For this reason Promise are born as a solution to this problem Promises The promises are objects that represent the completion of a process this can be a failure reject or a success resolve Also lets add this beauty Everything seemed magical until Using async await makes the code more readable it looks more beautiful but it has a problem is that if the promise fails it will stop the flow of our system so it is necessary to handle the errors But when handling these with trycatch we lose that readability but don t worry those are over now my dear friend How implemented First we are going to simulate a whole Let s do it We define some interfaces and add test content interface Note id number name string interface Query key string any const notes Note id name Megadeth id name Korn We define some functions async function update id number data Omit lt Note id gt options Query Promise lt Note gt const index number notes findIndex n gt n id id if index lt throw new Error Note does not exist const updated Note id data notes splice index updated return updated async function remove id number options Query Promise lt Note gt const index number notes findIndex n gt n id id if index lt throw new Error Note does not exist const note Note notes index notes splice index return note We define our promise handler async function promHandler lt T gt prom Promise lt T gt Promise lt T null any gt try return await prom null catch error return null error Now we only consume our handler const updated err await promHandler update name Mudvayne updated gt id name Mudvayne err gt null const removed error await promHandler remove removed gt null error gt Error Does not exist Now I ask you does it look better Perfect we already know how to avoid trycatch hell but this only using promises what about synchronous functions Handling synchronous functions We convert our previous functions to synchronous function update id number data Omit lt Note id gt options Query Note function remove id number options Query Note We define our synchronous function handler function funcHandler lt T extends any K gt func args T gt K params T K null any try return func params null catch error return null error We carry out the operations const updated err funcHandler update name Mudvayne updated gt id name Mudvayne err gt null const removed error funcHandler remove removed gt null error gt Error Does not exist Great we no longer have to struggle to make our code look more readable and also we reuse the handles You know if you have something to contribute a question an improvement you can contribute in the comments and if it has been useful leave your reaction that makes me happy |
