import { exists } from "https://deno.land/std@0.202.0/fs/exists.ts";
Test whether or not the given path exists by checking with the file system. Please consider to check if the path is readable and either a file or a directory by providing additional options
:
import { exists } from "https://deno.land/std@0.202.0/fs/mod.ts";
const isReadableDir = await exists("./foo", {
isReadable: true,
isDirectory: true
});
const isReadableFile = await exists("./bar", {
isReadable: true,
isFile: true
});
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@0.202.0/fs/mod.ts";
if (await exists("./foo")) {
await Deno.remove("./foo");
}
Good:
// Notice no use of exists
try {
await Deno.remove("./foo", { recursive: true });
} catch (error) {
if (!(error instanceof Deno.errors.NotFound)) {
throw error;
}
// Do nothing...
}
Parameters
path: string | URL
