How can I use json5 for the endpoints in LB?

Can I switch out the default JSON parser for JSON5 API somehow?

I could only find one single reference to JSON5.. by myself on a closed issue ;-) strongloop/loopback#4247

Hello world. In lb3 can we trap errors in a remote call in some middleware?

For e.g. consider there is a model. and we try to create a record via the http api POST /api/Customers with some irrelevant json data...

There would be some output on the console to this reflect this...

what middleware is responsible for that...? And how do I put my middleware before it?

Okay. never mind. I found the answer.

Hello Community

I posted a question related to an issue I am facing with postgres connector here: https://groups.google.com/g/loopbackjs/c/vY3ykgBgH3Q/m/MIb3Gqq3AAAJ. Can I assume the community is fairly active to get a response ? Just trying to figure this thing out asap.

Hi
I am using loopback 4 for backend and react for front end.
when I make a request on API, it gives me blocked Cors.

I tried this :
let config = {
mode: 'cors',
cache: 'no-cache',
credentials: 'same-origin',
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json',
},
redirect: 'follow',
referrerPolicy: 'no-referrer',
}
const response = await axios.post(${API}/signUppatient, obj, config);
but it didn't work

Hi everyone. I have a quiestion. I'm using a datasource that I successfully could connect to my rest service.The thing is that I need to use a POST endpoint that expects a multipart/form-data. But I don't know how to pass the Buffer I have in memory to send to my endpoint

Here is the config for my datasource:

const config = {
  name: 'ipfs',
  connector: 'rest',
  baseURL: 'http://localhost:5001/api/v0/',
  crud: false,
  operations: [
    {
      template: {
        method: 'POST',
        url: 'http://localhost:5001/api/v0/add',
        headers: {
          'content-type': 'multipart/form-data;'
        },
        query: {
          'only-hash': true,
        },
        form: {
          file: '{file}',
        },
      },
      functions: {
        getCID: ['file'],
      },
    },
    {
      template: {
        method: 'POST',
        url: 'http://localhost:5001/api/v0/bootstrap/list',
      },
      functions: {
        getPeers: [],
      },
    },
  ],
};

Mesi Rendón

@mesirendon

Here's how I'm defining the interface:

export interface Ipfs {
  getCID(file: Buffer): Promise<CID>,
  getPeers(): Promise<unknown>
}

This was a nightmare, just to let you know guys.... I've ended installing axios and creating a local service. But I'm still wondering how to do it using the loopback-connector-rest module

Hi, i came from an lb3 application, there I have a view folders with some .pug templates. Can I migrate them also to my new lb4 app ? How can i define a route that renders a template instead of a json response ?

Henrik Holst

@hholst80

We migrated from lb2 to lb3 this summer and just realized that a long standing bug was caused by the upgrade. We have had a customer using the array of object functionality and apparently we need to enable allowArray in an option somewhere. However, I have not found where this option should be inserted. In the model json description I assume, but where?
