Operations

Eicrud's services offer the following CRUD methods out of the box. Check out the client page to call them from your front end.

Warning

In the following examples CRUD methods are called directly from CrudServices, this means Security rules are not enforced and Validations/Transforms are not applied. All these checks happen at the controller level.

Create Operations

$create

Create a new entity.

const newProfile: Partial<Profile> = {
    userName: "Jon Doe",
    owner: ctx.userId
}
await profileService.$create(newProfile, ctx);

$createBatch

Create new entities.

const newProfiles: Partial<Profile>[] = [
    {
    userName: "Jon Doe",
    owner: '507f1f77bcf86cd799439011'
    },
    {
    userName: "Sarah Doe",
    owner: '507f191e810c19729de860ea'
    },
]

await profileService.$createBatch(newProfiles, ctx);

Read Operations

$findOne

Find an entity.

const query: Partial<Profile> = {
    userName: "Jon Doe",
}
const res: Profile = await profileService.$findOne(query, ctx);

$find

Find entities.

const query: Partial<Profile> = {
    astroSign: "Aries"
}
const {data, total, limit} = await profileService.$find(query, ctx);

$findIn

Find entities with IDs included in the provided list.

const ids = ['4d3ed089fb60ab534684b7e9', '4d3ed089fb60ab534684b7ff']
const {data, total, limit} = await profileService.$findIn(ids, {}, ctx);

Update Operations

$patchOne

Update an existing entity.

const query: Partial<Profile> = {
    id: user.profileId
}
const update: Partial<Profile> = {
    bio: "Hello world"
}
await profileService.$patchOne(query, update, ctx); 

Note

$patchOne will throw if the queried entity doesn't exist.

$patch

Update every entity that matches a query.

const query: Partial<Profile> = {
    astroSign: "Aries"
}
const update: Partial<Profile> = {
    bio: "Is passionate and motivated."
}
await profileService.$patch(query, update, ctx);

Note

$patch returns the number of entities affected by the operation

$patchIn

Update entities with IDs included in the provided list.

const ids = ['4d3ed089fb60ab534684b7e9', '4d3ed089fb60ab534684b7ff']
const update: Partial<Profile> = {
    bio: "Is nice."
}
await profileService.$patch(query, update, ctx);

$patchBatch

Perform multiple $patch operations.

const updates = [
    {
        query: {
            astroSign: "Leo"
        },
        data: {
            bio: "Is generous."
        }
    },
    {
        query: {

        data: {
            bio: "Is relaxed."
        }
    },
]

await profileService.$patchBatch(updates, ctx);

Note

Updating to undefined has no effect.

await profileService.$patchOne({ id: user.profileId }, { bio: undefined }, ctx);
// will not delete the profile bio

await profileService.$patchOne({ id: user.profileId }, { bio: null }, ctx);
// will set the bio to null
