try-monad
A small, reasonably featureful wrapper for somewhat more fluent use of try/catch in javascript.
Install:
yarn add try-monador
npm install --save try-monadYou know how it works.
Use:
Read the source code! It's really basic and has tons of inline doc comments and whatnot.
Use (for lazy people only):
import Try from 'try-monad';
const tryMyThing = Try(() => { dangerouslyComputeThing(); });
if (tryMyThing.isSuccess) {
console.log("a winner is me!");
console.log("won with: " + tryMyThing.orThrow());
}
if (tryMyThing.isFailure) {
console.log("darnit");
tryMyThing.handle(err => {
console.log("failed with: " + err);
});
}
tryMyThing.map(result => "RESULT: " + result);
tryMyThing.flatMap(result => Try(() => anotherDangerousThing(result)));
tryMyThing.fold(value => ..., error => ...);Does it serialize?
You bet it does:
JSON.stringify(Try.success(1))
// {"success": true, "value": 1}
JSON.stringify(Try.fail("bah!"))
// {"success": false, "error": "bah!"}
Is it one of those Thenable things?
ugh. yes. yes it is. give it a whirl and see.
