How to access node module documentation - eslint - node.js

I'm working on a project that wraps ESLint output, and would like to access the content of the detailed markdown documentation for each warning. These files live in the ESLint repository at docs/rules.
However, it looks like the docs directory might not get included in the packaged module, and so those docs might not be accessible from the standard product once installed.
The npm package.json docs also make it seem like docs may not typically be available:
directories.doc
Put markdown files in here. Eventually, these will be displayed
nicely, maybe, someday.
I'm new to working with node packages, so may be missing something obvious. Thanks for any ideas!

OP here. In the end, I worked with a friend on an ESLint fork that adds this functionality: https://github.com/codeclimate/eslint/commit/fb68870708b1b3bbad80a955eec085a8dfd5f13b
If anyone would like to use it, you can use our fork of eslint and access docs for each rules through:
var docs = require("eslint").docs;
where docs is an object with { rule_name: "content string....", ... }
complexity_readup = docs.get("complexity")

Using music21j in node js, not in browser

I'm attempting to run music21j in node js ( repo link , npm link ).
I get ReferenceError: self is not defined
When trying to simply initialize music21j:
const music21 = require('music21j');
const n = new music21.note.Note('F#');
Does this mean it's not possible to run outside of the browser, or am I somehow initializing to the wrong environment?
The github documentation states
...or use it in your javascript/typescript project
, hence my confusion.
From the github repo:
At present it's not possible to run outside of the browser. :-( But we're working on removing certain JQuery patches that should make it easier to do. You may however need to use ES6-style imports.

Integrating jQuery-File-Upload plugin with blueimp-file-upload-node npm module

I am trying to integrate the jQuery-File-Upload (https://github.com/blueimp/jQuery-File-Upload) with the npm module "blueimp-file-upload-node" to process file uploads.
Sadly, this package "blueimp-file-upload-node" has not been documented yet.
The frontend integration is working correctly, but I am struggling to get the upload functionality working.
I have read and followed this section:
https://github.com/blueimp/jQuery-File-Upload/wiki/Setup#using-jquery-file-upload-ui-version-with-nodejs which tells me to start the service by running:
./node_modules/blueimp-file-upload-node/server.js (notice, the path of this file is within my node_modules folder)
I would like to have the file uploader as a route of my app, (i.e. /upload) not a separate service, on a different port.
How would I go about that?
My code is here:
https://github.com/robsilva/fileUploader
I really appreciate if anyone can shed some light here.
Seems like you are looking for the express middleware

Can I have a project-specific custom code deprecation message using eslint?

I have a node.js project that checks itself for code consistency according to rules specified in .eslintrc using gulp and gulp-eslint.
Now, I would like to have it throw custom deprecation warnings when it encounters a certain require:
const someModule = require('myDeprecatedModule');
// Warning: myDeprecatedModule is deprecated. Use myNewModule in stead.
Is this possible in a simple way that will be picked up by IDE's too?
Using .eslint
No custom plugin to be published and installed using npm
Local code only that can be pushed to the repository, nothing global
No custom code in node_modules
The rule no-restricted-modules does exactly this: it disallows requiring certain modules.
The names of the deprecated modules must be coded in the configuration. So in order to disallow the deprecated myDeprecatedModule you would add this setting to your .eslintrc file under the "rules" section.
"no-restricted-modules": ["error", "myDeprecatedModule"]
I don't think it's possible to customize the error message though. That would be possible with a custom plugin.

How should I use Swagger with Hapi?

I have a working ordinary Hapi application that I'm planning to migrate to Swagger. I installed swagger-node using the official instructions, and chose Hapi when executing 'swagger project create'. However, I'm now confused because there seem to be several libraries for integrating swagger-node and hapi:
hapi-swagger: the most popular one
hapi-swaggered: somewhat popular
swagger-hapi: unpopular and not that active but used by the official Swagger Node.js library (i.e. swagger-node) as default for Hapi projects
I though swagger-hapi was the "official" approach, until I tried to find information on how do various configurations on Hapi routes (e.g. authorization, scoping, etc.). It seems also that the approaches are fundamentally different, swagger-hapi taking Swagger definition as input and generating the routes automatically, whereas hapi-swagger and hapi-swaggered seem to have similar approach with each other by only generating Swagger API documentation from plain old Hapi route definitions.
Considering the amount of contributors and the number of downloads, hapi-swagger seems to be the way to go, but I'm unsure on how to proceed. Is there an "official" Swagger way to set up Hapi, and if there is, how do I set up authentication (preferably by using hapi-auth-jwt2, or other similar JWT solution) and authorization?
EDIT: I also found swaggerize-hapi, which seems to be maintained by PayPal's open source kraken.js team, which indicates that it might have some kind of corporate backing (always a good thing). swaggerize-hapi seems to be very similar to hapi-swagger, although the latter seems to provide more out-of-the-box functionality (mainly Swagger Editor).
Edit: Point 3. from your question and understanding what swagger-hapi actually does is very important. It does not directly serves the swagger-ui html. It is not intended to, but it is enabling the whole swagger idea (which the other projects in points 1. and 2. are actually a bit reversing). Please see below.
It turns out that when you are using swagger-node and swagger-hapi you do not need all the rest of the packages you mentioned, except for using swagger-ui directly (which is used by all the others anyways - they are wrapping it in their dependencies)
I want to share my understanding so far in this hapi/swagger puzzle, hope that these 8 hours that I spent can help others as well.
Libraries like hapi-swaggered, hapi-swaggered-ui, also hapi-swagger - All of them follow the same approach - that might be described like that:
You document your API while you are defining your routes
They are somewhat sitting aside from the main idea of swagger-node and the boilerplate hello_world project created with swagger-cli, which you mentioned that you use.
While swagger-node and swagger-hapi (NOTE that its different from hapi-swagger) are saying:
You define all your API documentation and routes **in a single centralized place - swagger.yaml**
and then you just focus on writing controller logic. The boilerplate project provided with swagger-cli is already exposing this centralized place swagger.yaml as json thru the /swagger endpoint.
Now, because the swagger-ui project which all the above packages are making use of for showing the UI, is just a bunch of static html - in order to use it, you have two options:
1) to self host this static html from within your app
2) to host it on a separate web app or even load the index.html directly from file system.
In both cases you just need to feed the swagger-ui with your swagger json - which as said above is already exposed by the /swagger endpoint.
The only caveat if you chose option 2) is that you need to enable cors for that end point which happened to be very easy. Just change your default.yaml, to also make use of the cors bagpipe. Please see this thread for how to do this.
As #Kitanotori said above, I also don't see the point of documenting the code programmatically. The idea of just describing everything in one place and making both the code and the documentation engine to understand it, is great.
We have used Inert, Vision, hapi-swagger.
server.ts
import * as Inert from '#hapi/inert';
import * as Vision from '#hapi/vision';
import Swagger from './plugins/swagger';
...
...
// hapi server setup
...
const plugins: any[] = [Inert, Vision, Swagger];
await server.register(plugins);
...
// other setup
./plugins/swagger
import * as HapiSwagger from 'hapi-swagger';
import * as Package from '../../package.json';
const swaggerOptions: HapiSwagger.RegisterOptions = {
info: {
title: 'Some title',
version: Package.version
}
};
export default {
plugin: HapiSwagger,
options: swaggerOptions
};
We are using Inert, Vision and hapi-swagger to build and host swagger documentation.
We load those plugins in exactly this order, do not configure Inert or Vision and only set basic properties like title in the hapi-swagger config.

sendgrid make test throws errors

I'm running node on my vps server. node is at my root, my app.js with node_modules (express, socket.io) are in /home/vps/public_html/
when following github readme for setting up sendgrid i run into trouble:
config.js is not live by the sounds of it as when I run sendgrids simple code example if i
a.) refer to config.js by doing:
var sendgrid=new SendGrid(user,key);
node kills its self because user is not defined.
b.) bypass config.js by doing:
var sendgrid=new SendGrid({user:'my_user_name',key:'my_password'});
I get console.log(message) of [ 'Permission denied, wrong credentials' ]
here is another image this one is of my public_html structure:
does any one know how to activate this config.js?
Should I have installed node.js into my public_html in the beginning?
So, there are a few things wrong here:
1) We have a typo in the README (which has now been updated)
tl;dr - you should type npm test not make test
Essentially, you're typing make test and make is coming back and saying "Hey, there's no rule for test in the cwd. It doesn't look like there's anything for me to do. Bye!". If you look carefully, there is no Makefile in the node library, so there's obviously not going to be any rules. So make definitely won't work in this case. What the README should have said is npm test. NPM is the package manager for node and it has a helper method test which runs all the tests for a given module.
Also, just to be clear - when you're typing npm test, all you are doing is running the tests for the library. Really this should only be necessary if you're adding features or fixing bugs on the library itself. If you're trying to use the library to send email, you should read the section titled "Usage".
2) You have a typo in your code (which is why the other sample didn't work)
Your code looks like this:
var sendgrid = new SendGrid({user:'my_user_name', key:'my_password'});
The code sample that we provide looks like this:
var sendgrid = new SendGrid(user, key);
Notice the difference? You're passing in a javascript object and we're expecting two discrete string values instead. The library is interpreting that as your username is "{user:'my_user_name', key:'my_password'}" with no password (because you didn't provide a second parameter). Instead you should do the following:
var sendgrid = new SendGrid("my_user_name", "my_password");
