Loopback-next: Running passport login example in CLI

[HrithikMittal]

While using the CLI to install the example of passport login by

lb4 example passport-login

It's show error when installing the dependency '@loopback/mock-oauth2-provider@^0.0.3'

[deepakrkris]

for time being please open package.json and remove "@loopback/mock-oauth2-provider": "^0.0.3", under dev dependencies.

[deepakrkris]

also delete ../loopback4-example-passport-login/src/__tests__/acceptance/passport-login.acceptance.ts and then do an npm I, you should be able to start the app then.

@deepakrkris We need to publish @loopback/mock-oauth2-provider. Let me see what I can do.

[raymondfeng]

See @loopback/[email protected]. It' on npm now.

[HrithikMittal]

Ya, it's available now. Thank you

[HrithikMittal]

Hey @raymondfeng and @deepakrkris I am still facing a problem while running this

I also try to install the package 'npm install @types/loopback__mock-oauth2-provider' but it is not available.
and I also try by removing the package and
"
also delete ../loopback4-example-passport-login/src/__tests__/acceptance/passport-
login.acceptance.ts and then do an npm I, you should be able to start the app then.
"
but still, it showing the error

[raymondfeng]

No @types/... is needed. Our packages are built in TypeScript and they come with TS d.ts files.

[raymondfeng]

Hmm, the package.json is missing types and main.

[HrithikMittal]

then what to do now? Please can you make the changes?

[raymondfeng]

You can delete the acceptance tests.

[raymondfeng]

We'll have to post a new version

[raymondfeng]

@HrithikMittal To try the example, you can do the following:

git clone [email protected]:strongloop/loopback-next.git
cd loopback-next
npm ci
npm run build
cd examples/passport-login
npm start

@mathias22osterhagen22 You don't seem to have ssl key set up for your git account. But you should be able to run:

git clone https://github.com/strongloop/loopback-next.git

I will wait for the release, all the documentation part about authentication + authorization is really difficult to understand.

@mathias22osterhagen22 You need to follow these steps:

git clone https://github.com/strongloop/loopback-next.git
cd loopback-next
npm ci
npm run build
cd examples/passport-login
npm start

[deepakrkris]

@mathias22osterhagen22 you will have to create the oauth template spec as per https://github.com/strongloop/loopback-next/tree/master/examples/passport-login#create-oauth2-providersjson
