# mongoose-findone-or-error
Simple Mongoose plugin for rejecting findOne and findById promises which resolve null.
# Installation
Hook the plugin to a schema:
```javascript
// global level
const mongoose = require('mongoose');
const findOrErrorPlugin = require('mongoose-findone-or-error');
mongoose.plugin(findOrErrorPlugin);
// schema level
// example.js
const mongoose = require('mongoose');
const findOrErrorPlugin = require('mongoose-findone-or-error');
const schema = new mongoose.Schema({
name: String,
description: String
});
schema.plugin(findOrErrorPlugin);
mongoose.model('Example', schema);
```
## Usage
#### Execute use statics method
```javascript
const Example = require('./example');
// use with statics findByIdOrError
// 1. Promise
Example.findByIdOrError('idNotInDatabase')
.then(doc => {
console.log('Only executed when document is found');
})
.catch(err => {
console.log(err);
});
// 2. Callback
Example.findByIdOrError('idNotInDatabase', function(err, doc) {
if (err) {
console.log('Here not found error');
return
}
console.log('Only executed when document is found');
})
// or use with statics findOneOrError
Example.findOneOrError({ name: 'plugin example' })
.then(doc => {
console.log('Only executed when document is found');
})
.catch(err => {
console.log(err);
});
Example.findOneOrError({ name: 'plugin example' }, function(err, doc) {
if (err) {
console.log('Here not found error');
return
}
console.log('Only executed when document is found');
})
```
#### Execute use query helpers:
```javascript
const Example = require('./example');
// 1. Promise
Example.findOne({ name: 'plugin example' })
.select({name: 1})
.throwEmpty() // <- add this line before .then() or .exec()
.limit(10)
.then(doc => {
console.log('Only executed when document is found');
})
.catch(err => {
console.log(err);
});
// 2. Promise
// or set option emptyError
Example.findOne({
name: 'plugin example'
}, null, {
lean: true, // other option
emptyError: true // <- add this option
})
.then(() => {
console.log('Only executed when document is found');
})
.catch(err => {
console.log(err);
});
// 3. Callback
Example.findOne({
name: 'plugin example'
}, '_id name', {
emptyError: true // <- add this option
}, function(err, doc) {
if (err) {
console.log('Here not found error');
return
}
console.log('Only executed when document is found');
})
// findById same as findOne
...
```
#### Default Error Handle
```javascript
// modelName: return the mode name
// query: return Query.getQuery()
// emptyQueryOption: return Query.getOptions()[queryOption]
function defaultSendEmptyError (modelName, query, emptyQueryOption) {
const error = new Error(`${_.upperFirst(_.camelCase(modelName))} not found.`)
error.name = 'DocumentNotFoundError'
if (!_.isBoolean(emptyQueryOption)) { error.code = emptyQueryOption }
return error
}
```
## Plugin Options
```javascript
// default options
schema.plugin(findOrErrorPlugin, {
static: { // set `false` disable both findOneOrError and findByIdOrError
findOneFname: 'findOneOrError', // custom function name or set `false` disable it
findByIdFname: 'findByIdOrError' // custom function name or set `false` disable it
},
query: { // set `false` disable query helpers
queryFname: 'throwEmpty', // use .throwEmpty(true) or .throwEmpty(404)
queryOption: 'emptyError' // use { emptyError: true } or { emptyError: 404 }
},
sendEmptyError: sendEmptyError // must reutrn an instanceof Error
});
```
Error With `code`
```javascript
// .throwEmpty(code)
Example.findOne({ name: 'plugin example' })
.select({name: 1})
.throwEmpty(404) // set code to error.code
.limit(10)
.then(doc => {
console.log('Only executed when document is found');
})
.catch(err => {
console.log(err.code) // 404
});
// { emptyError: code }
Example.findOne({
name: 'plugin example'
}, '_id name', {
emptyError: 404
}, function(err, doc) {
if (err) {
console.log(err.code) // 404
return
}
console.log('Only executed when document is found');
})
```
