Deprecated
(will be removed after 0.157.0) Checking the state of a file before using it causes a race condition. Perform the actual operation directly instead.
import { exists } from "https://dotland.deno.dev/std@0.181.0/fs/exists.ts";
Test whether or not the given path exists by checking with the file system.
Note: do not use this function if performing a check before another operation on that file. Doing so creates a race condition. Instead, perform the actual file operation directly.
Bad:
import { exists } from "https://deno.land/std@0.181.0/fs/mod.ts";
if (await exists("./foo.txt")) {
await Deno.remove("./foo.txt");
}
Good:
// Notice no use of exists
try {
await Deno.remove("./foo.txt");
} catch (error) {
if (!(error instanceof Deno.errors.NotFound)) {
throw error;
}
// Do nothing...
}
