Help with implementing in a Nodejs environment

[Atitlanio]

Hey, I'm having trouble getting this to work with the code provided in the README. I would like to have the capability to add posts from a nodejs backend.

I've played around with the README code a bit. I added packages including @sniptt/monads, class-transformer, [email protected] and reflect-metadata. I wasn't quite sure what needs to be included with in the headers?

I have the following and I'm attempting to log in using an administrator account. What's the purpose of retrieving a jwt once logged in?

import {{ LemmyHttp }} from 'lemmy-js-client';

var loginForm = {
    username_or_email: "username",
    password: "password"
};

var baseUrl = 'https://mydomain.io';
var client = new LemmyHttp(baseUrl);
var jwt = await client.login(loginForm).jwt;

Apologies if I'm missing something simple! Appreciate any guidance 🙏

okay, so I understand the jwt (used the unwrap() function to get the token) is for the auth and seem to have gotten it to work with the following code

import { LemmyHttp } from 'lemmy-js-client';

var loginForm = {
    username_or_email: "username",
    password: "password"
};

var baseUrl = 'https://mydomain.io';
var client = new LemmyHttp(baseUrl);

async function getLogin() {
  const login = await client.login(loginForm);
  return login
}

getLogin().then( (res) => {
    const jwt = res.jwt.unwrap()
    client.createPost({auth: jwt, body:"this is a test post", name: "test post", community_id: 2 })
    .then( (res) => console.log(res))
})

Curious if there's a way I can more easily obtain a list of community_id's

Also, is there anyway for the body to have some formatting to it? e.g., a new line? \n didn't do anything for me

Much easier to make every function async, and then call .await, rather than endlessly chaining .then. Read about async / await for js.

What list of communities are you looking for?

Also, is there anyway for the body to have some formatting to it? e.g., a new line? \n didn't do anything for me

You're creating a post? \n\n should be for newlines, a single \n doesn't make one in commonmark.

Yeah I was trying that initially with the await keyword, however it was returning undefined so I moved it into the .then structure. Maybe I was doing something funky, I'll have to try it out again as it does seem cleaner.

Nevermind about the community_id question! I didn't realize at first that you can pass a name argument into client.getCommunity(), I thought it only allowed the id #.

the double \n\n worked, thank you! I am going to try implementing the code on my server and see if it works out. Appreciate the help!

Cool, okay I got everything working!! I'm using it to allow people to post help questions @ https://atitlan.io/help (just a mockup for now, this link might change in the future)

One thing I noticed in my setup was you guys have "node-fetch": "^3.2.9" in your dependencies.

I run into an error when I use this (same with v3.3.0), I get the following error:

.../node_modules/lemmy-js-client/dist/http.js:52
var node_fetch_1 = require("node-fetch");
                   ^

Error [ERR_REQUIRE_ESM]: require() of ES Module .../node_modules/node-fetch/src/index.js from .../node_modules/lemmy-js-client/dist/http.js not supported.
Instead change the require of index.js in /.../node_modules/lemmy-js-client/dist/http.js to a dynamic import() which is available in all CommonJS modules.

Node.js v18.8.0

According to stackoverflow it's simply a problem with using require instead of import.

I downgraded to node-fetch v2 (specifically 2.6.7) and it works!

Thanks for your help and highly appreciate your guys work on this 🚀

I've had weird problems with node-fetch too, sry about that. Your PR is merged.

I would recommend using import tho and not require, and of course using typescript and not javascript.
