[Error] When use 'api init' Error: Module did not self-register about optic

[lvenier]

@c0ncentus : I did use that link to set it up :
https://dashboard.useoptic.com/setup/express-js

The main change is
app.listen(process.env.OPTIC_API_PORT || process.env.PORT)
in your case :
app.listen(process.env.OPTIC_API_PORT || 3000)

I see you have

app.listen(3000, () => { console.log('My API is running...'); });

in your code example.

Hope it helps.

I will see later if I have another trouble ^^
depend on effort / simple of reproduce and what happened.

Hi @c0ncentus - The api init command doesn't start your server so I suspect it's something else, but you will eventually need to make the changes above (thanks @lvenier!).

It looks like you are running on Windows, which we have not tested rigorously. I am planning to get a Windows setup for testing soon, but in the meantime, if you continue to run into issues could you record a screencast so we can see all the steps and complete error messages?

import * as express from 'express';
// tslint:disable-next-line: no-duplicate-imports

const app = express();

app.get('/', (req: any, res: any) => { res.json({ test: 'Api is alive !' }); });
app.get('/Test', (req: any, res: any) => { res.json({ exTest: 'Expected this !' }); });

app.listen(process.env.OPTIC_API_PORT || 3000, () => { console.log('My API is running...'); });

export default app;

still the same issue

there it is : https://github.com/c0ncentus/test_Optic (the repo)

@c0ncentus thanks for the additional info!

When you run api init Optic doesn't know about your code yet. api init is the command that asks you questions so that it can learn how to run your code when you run the api start command. If you are having issues running api init, then it is most likely an installation issue.

Based on the original error message you shared:

Error: Module did not self-register    at Object.<anonymous> (C:/Users/Martin/AppData/Roaming/npm/node_modules/@useoptic/cli/node_modules/registry-js/dist/lib/registry.js:4:7)

it seems like the failure is that one of our dependencies is not working. The most likely cause is upgrading your node version without rebuilding Optic.

Can you npm uninstall and reinstall @useoptic/cli and let me know if you still run into the issue? I can not replicate your issue on the latest node 13 on Mac, so it would help to see exactly what you are seeing in the terminal when you install and run api init.

npm uninstall -g @useoptic/cli
npm install -g @useoptic/cli
