I am trying to build a natural language processing bot using javascript and jQuery for the logic and node and express as the framework. I discovered a natural language processing facility that would be extremely useful for my project https://github.com/NaturalNode/natural unfortunately the documentation is sparse and I have only been using node for a couple of weeks.
This is the code I have on my server side app.js
var natural = require('natural'),
tokenizer = new natural.WordTokenizer();
stemmer.attach();
var express = require("express");
app = express();
app.set("view engine", "ejs");
app.use(express.static(__dirname + '/public'));
I am requiring the 'natural' module here but I am unable to use the methods that are outlined in the documentation.
var natural = require('natural'),
tokenizer = new natural.WordTokenizer();
console.log(tokenizer.tokenize("your dog has fleas."));
// [ 'your', 'dog', 'has', 'fleas' ]
The method 'tokenizer' is undefined. I have done quite a bit of research on this and looked into using module.export and passing variables through the app.get function for the index.ejs page I am using but I have been unsuccessful so far.
NOTE: The javascript file I am trying to use these methods in is located in the public/javascript directory while the app.js file is located in the main project directory. I have tried to require the 'natural' package directly in the javascript file I am trying to use the methods in but an error was thrown saying require is an undefined method.
here is the package.json file:
{
"name": "JSAIN",
"version": "1.0.0",
"description": "",
"main": "app.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"ejs": "^2.3.1",
"express": "^4.12.3",
"natural": "^0.2.1",
"underscore": "^1.8.2"
}
}
也许您可以尝试使用browserify ,从而允许您在浏览器中使用某些npm模块。
Converting my comment into an answer...
The natural module says it's for running in the node.js environment. Unless it has a specific version that runs in a browser, you won't be able to run this in the browser.
have you install that module with global mode and have defined that in package.json? Otherwise, try this:
npm install -g natural
