Error when importing library

[Goby03]

Hello !
I follow the doc to import an external library in my plugin (https://github.com/PokeAPI/pokedex-promise-v2)

I my library.js, in plugin.init, I add this :

routeHelpers.setupPageRoute(router, '/pokemon/:param1', [(req, res, next) => {

  winston.info(`[plugins/pokemon] In middleware. This argument can be either a single middleware or an array of middlewares`);

  setImmediate(next);

}], async (req, res) => {

  const pokemonName = req.params.param1;

  let pokemonSpec, frenchName

  require('pokedex-promise-v2', async (Pokedex) => {

  	const P = new Pokedex();

  	pokemonSpec = await P.getPokemonSpeciesByName(pokemonName);

  	// // pokemonSpec = await P.getCharacteristicById(pokemonName);

  	frenchName = pokemonSpec.names.filter(pokeAPIName => pokeAPIName.language.name === 'fr')[0].name;



  });





  



  winston.info(`[plugins/pokemon] Navigated to ${nconf.get('relative_path')}/pokemon`);

  res.render('pokemon', { pokemon: pokemonName, frenchName : frenchName });

});

In plugin.json, I have this

"modules": {

  "../client/quickstart.js": "./static/lib/quickstart.js",

  "../admin/plugins/quickstart.js": "./static/lib/admin.js",

  "pokedex-promise-v2" : "./node_modules/pokedex-promise-v2"

},

When I try to go on the route, I have this error :

What I am doing wrong ?

@Goby03 require doesn't work like like on the server side.

Just put

const Pokedex = require('pokedex-promise-v2');

At the top of the file, then use it later

@PitaJ It's the first think I try, like I will do for any classical node projet. It doesn't work. I uust try again and it seems to block. NodeBB can't find my routes

Did you try

const Pokedex = await import('pokedex-promise-v2');
const P = new Pokedex();

As suggested by the above link.

@baris I just try and it doesn't change anything
Does it mean I will have to edit the base js of nodeBB to convert it to esm ?

That would be too much work, can you use an older version of 'pokedex-promise-v2' that allows commonjs usage.

Also what happened when you used.

const Pokedex = await import('pokedex-promise-v2');
const P = new Pokedex();

Are you seeing any error messages or is it just not returning anything in Pokedex?

[Goby03]

@baris No error, exept a "not found" on every route of libray.js

I feel silly. I hadn't thought to use an older version. It works ! Thank you very much !!!!
