示例1: async
async () => {
const adapterAsync = new FileAsync<DbSchema>("test.json");
const dbAsyncPromise = lowfp(adapterAsync);
const dbAsync = await dbAsyncPromise;
const postsWithDefault = dbAsync("posts", [{ title: "baz" }] as Post[]);
const func: Promise<Post[]> = postsWithDefault.write(post => [
...post,
{ title: "another" }
]);
};示例2: lowfp
() => {
const adapterLS = new LocalStorage<DbSchema>("test.json");
const dbFP = lowfp(adapterLS);
// Get posts
const postsFP: low.FpReturn<Post[], low.AdapterSync<DbSchema>> = dbFP(
"posts"
);
// replace posts with a new array resulting from concat
// and persist database
const write: Post[] = postsFP.write(
concat({ title: "lowdb is awesome", views: random(0, 5) })
);
// Find post by id
const post: Post = postsFP(find({ id: 1 }));
// Find top 5 fives posts
const popular: Post[] = postsFP([
sortBy("views") as PostsAction,
take(5) as PostsAction
]);
const filtered: Post[] = dbFP("posts")(filter({ published: true }));
const writeAction: Post[] = dbFP("posts").write(concat({ id: "123" }));
const writeAction2: string = dbFP(["user", "name"]).write(set("typicode"));
async () => {
