express-sequelize-crud

import crud, { sequelizeCrud } from 'express-sequelize-crud'

app.use(crud('/admin/users', sequelizeCrud(User)))

Expose resource CRUD (Create Read Update Delete) routes for Express & Sequelize (and other ORMs in v6+). Compatible with React Admin Simple Rest Data Provider

Note: Content-Range header

For getList methods, the response includes the total number of items in the collection in X-Total-Count header. You should use this response header for pagination and avoid using Content-Range header if your request does not include a Range header. Checkout this stackoverflow thread for more info.

If you are using ra-data-simple-rest, please refer to the documentation to use X-Total-Count for pagination.

Install

yarn add express-sequelize-crud

Usage

Simple use case

import express from 'express'
import crud, { sequelizeCrud } from 'express-sequelize-crud'
import { User } from './models'

const app = new express()
app.use(crud('/admin/users', sequelizeCrud(User)))

Limit actions

import express from 'express'
import crud, { sequelizeCrud } from 'express-sequelize-crud'
import { User } from './models'

const app = new express()
app.use(
  crud('/admin/users', {
    ...sequelizeCrud(User),
    destroy: null,
  })
)

Custom filters

Custom filters such as case insensitive filter can be perform like this:

import express from 'express'
import { Op } from 'sequelize'
import crud, { sequelizeCrud } from 'express-sequelize-crud'
import { User } from './models'

const app = new express()
app.use(
  crud('/admin/users', sequelizeCrud(User), {
    filters: {
      email: value => ({
        [Op.iLike]: value,
      }),
    },
  })
)

Custom behavior & other ORMs

import express from 'express'
import crud from 'express-sequelize-crud'
import { User } from './models'

const app = new express()
app.use(
  crud('/admin/users', {
    getList: ({ filter, limit, offset, order, opts: { req, res } }) =>
      User.findAndCountAll({ limit, offset, order, where: filter }),
    getOne: (id, { req, res }) => User.findByPk(id),
    create: (body, { req, res }) => User.create(body),
    update: (id, body, {req, res}) => User.update(body, { where: { id } }),
    destroy: (id, { req, res }) => User.destroy({ where: { id } }),
  })
)

Search

Autocomplete

When using react-admin autocomplete reference field, a request is done to the API with a q filter. Thus, when using the autocomplete field in react-admin, you must specify the behavior to search the records. This could looks like:

app.use(
  crud('/admin/users', {
    search: async (q, limit) => {
      const { rows, count } = await User.findAndCountAll({
        limit,
        where: {
          [Op.or]: [
            { address: { [Op.iLike]: `${q}%` } },
            { zipCode: { [Op.iLike]: `${q}%` } },
            { city: { [Op.iLike]: `${q}%` } },
          ],
        },
      })

      return { rows, count }
    },
  })
)

express-sequelize-crud exposes a default search helper function sequelizeSearchFields. Internally it uses LIKE syntax for all columns except uuid (type: DataTypes.UUID)

Here is an example:

import crud, {
  sequelizeCrud,
  sequelizeSearchFields,
} from 'express-sequelize-crud'

crud('/admin/users', {
  ...sequelizeCrud(User),
  search: sequelizeSearchFields(User, ['address', 'zipCode', 'city']),
})

When searching some stuff, the following records will be returned in this order:

1. records with a searchable field that contains some stuff
2. records that have searchable fields that contain both some and stuff
3. records that have searchable fields that contain one of some or stuff

The search is case insensitive by default. You can customize the search to make it case sensitive or use a scope:

import { Op } from 'sequelize'

const search = sequelizeSearchFields(
  User,
  ['address', 'zipCode', 'city'],
  Op.like
)

Contribute

This lib uses semantic-release. You need to write your commits following this nomenclature:

• feat: A new feature
• fix: A bug fix
• docs: Documentation only changes
• style: Changes that do not affect the meaning of the code (white-space, - formatting, missing semi-colons, etc)
• refactor: A code change that neither fixes a bug nor adds a feature
• perf: A code change that improves performance
• test: Adding missing or correcting existing tests
• chore: Changes to the build process or auxiliary tools and libraries such as documentation generation

To trigger a major version release write in the core of the commit message:

feat: my commit
