Hi, how are you?
I want to find data in the database and put it in json form.
Json's response is executed before data is found and contained, so where should I use wait to find data and then respond?
It's too difficult because of the map function in the middle
Originally, I used it right away without making it as a function, but I made it separately because I heard that wait is used in front of the function. Help me.
After the response, the data is found well. How do I transform it?
// Lookup for posts
router.get("/", async (req, res) => {
const datas = await Post.findAll(
{ { order: [["createdAt", "DESC"]] }
);
function findLike() {
datas.map(async (e) => {
const likeCount = await Like.findAll({ where: { postId: e.postId } });
e.likes = likeCount.length;
});
}
function response() {
res.json({
data: datas.map((e) => {
return {
postId: e.postId,
userId: e.userId,
nickname: e.nickname,
title: e.title,
createdAt: e.createdAt,
updatedAt: e.updatedAt,
likes: e.likes,
};
}),
});
}
await findLike();
await response();
});
// Look up posts
router.get("/", async (req, res) => {
const datas = await Post.findAll(
{ { order: [["createdAt", "DESC"]] }
);
datas.map(async (e) => {
const likeCount = await Like.findAll({ where: { postId: e.postId } });
e.likes = likeCount.length;
res.json({
data: datas.map((e) => {
return {
postId: e.postId,
userId: e.userId,
nickname: e.nickname,
title: e.title,
createdAt: e.createdAt,
updatedAt: e.updatedAt,
likes: e.likes,
}
})
});
});
});
