Elasticsearch Client for Deno Runtime


Getting Started

Connect and Check the Health of Elasticsearch

import { Client as ElasticsearchClient } from 'https://deno.land/x/elasticsearch@v1.0.0/mod.ts'
import type { HealthResponse } from 'https://deno.land/x/elasticsearch@v1.0.0/mod.ts'

const client = new ElasticsearchClient({ node: 'http://localhost:9200' })

const health: HealthResponse = await client.health()

Connect with Auth

const elasticUsername = Deno.env.get('ELASTIC_USERNAME')!
const elasticPassword = Deno.env.get('ELASTIC_PASSWORD')!

const client = new ElasticsearchClient({
    node: 'https://deno-elastic.es.us-central1.gcp.cloud.es.io:9243',
    auth: {
        username: elasticUsername,
        password: elasticPassword
    }
})

import type { SearchResponse } from 'https://deno.land/x/elasticsearch@v1.0.0/mod.ts'

interface Source {
    id: number
    title: string
}

const result = await client.search<Source>('test-index', {
    query: {
        match: {
            title: 'Deno'
        }
    }
})

Indices

import type {
    CatIndicesResponse,
    IndicesFindResponse,
    IndicesCreateResponse,
    IndicesCreateBody,
    IndicesDeleteResponse,
    IndicesStatusResponse,
    IndicesSettingsFindResponse
} from 'https://deno.land/x/elasticsearch@v1.0.0/mod.ts'

const indices = await client.indices.findAll()

const indice = await client.indices.find('test-index')

const createIndiceBody: IndicesCreateBody = {}
await client.indices.create('test-index', createIndiceBody)

await client.indices.delete('test-index')

const exists = await client.indices.exists('test-index')

await client.indices.close('test-index')

await client.indices.open('test-index')

const settings = await client.indices.settings('test-index')

Documents

import type {
    DocumentsFindResponse,
    DocumentsIndexResponse,
    DocumentsDeleteResponse
} from 'https://deno.land/x/elasticsearch@v1.0.0/mod.ts'

const document = await client.documents.find<Source>('test-index', '1')

await client.documents.create('test-index', '1', {
    id: 1,
    title: 'My title'
})

await client.documents.upsert('test-index', '1', {
    id: 1,
    title: 'My new title'
})

await client.documents.upsert('test-index', '1')

const exists = await client.documents.exists('test-index', '1')

Error Handling

try {
    const result = await client.indices.find('test-index')
} catch (err) {
    console.log(err)
}
