I'm getting "typesense is not defined" whenever I try to run... I followed everything in the Install/configure guide...

Could you paste your codes?

var fs = require('fs'); var readline = require('readline'); let client = new Typesense.Client({     'nodes': [{       'host': 'localhost',       'port': '8108',       'protocol': 'http'     }],     'apiKey': '<API_KEY>',     'connectionTimeoutSeconds': 2   }) let booksSchema = {     'name': 'books',     'fields': [         {'name': 'title', 'type': 'string' },         {'name': 'authors', 'type': 'string[]' },         {'name': 'image_url', 'type': 'string' },         {'name': 'publication_year', 'type': 'int32' },         {'name': 'ratings_count', 'type': 'int32' },         {'name': 'average_rating', 'type': 'float' },         {'name': 'authors_facet', 'type': 'string[]', 'facet': true },         {'name': 'publication_year_facet', 'type': 'string', 'facet': true },     ],     'default_sorting_field': 'ratings_count' } client.collections().create(booksSchema)   .then(function (data) {     console.log(data)   }) readline.createInterface({     input: fs.createReadStream('./books.jsonl'),     terminal: false }).on('line', function(line) {    let bookDocument = JSON.parse(line);    client.collections('books').documents().create(bookDocument) }); let searchParameters = {     'q'         : 'harry',     'query_by'  : 'title',     'sort_by'   : 'ratings_count:desc'   }      client.collections('books')     .documents()     .search(searchParameters)     .then(function (searchResults) {       console.log(searchResults)     })

Did you run

npm i

in your working director?

yes

where is your typesense import?

import Typesense from 'typesense'

@Tim Jang Echoing what Masahiro said, you want to add either an import statement or require statement to get that block of code to work.
