crc-pdf-generator
is a NodeJS based service that is responsible for generating a PDF Report.
For local development you can edit the passed data in the src/index.js
file. Then to view the changes in real time
in the browser just do:
npm ci
docker-compose up
npm run start:server
This will start the react scripts and will serve just the react app on localhost:8000.
This development will not have the header, but the content of the page will be printed identically into the PDF making this approach much faster to make changes to the PDF.
oc port-forward -n crc-pdf-generator svc/crc-pdf-generator-api 8000:8000
Follow the check list to integrate your service with the PDF generator
You currently have 2 choices for generating any of the available templates:
The generate endpoint will automatically download the template if it is available (requires the above-mentioned headers)
POST http://localhost:8000/api/crc-pdf-generator/v2/generate
The request body:
type RequestBody = {
service: string; // service name
template: string; // template name
[key: string]: any // additional API request config attributes
}
The preview endpoint will instead return the pdf preview environment:
GET http://localhost:8000/preview
While this endpoint is currently only available for local testing, the preview environment will eventually be exposed in production as well.
To download the report, you will need a small piece of JS code. Here is an example of downloading ROS executive report:
// use fetch or XHR.
fetch('/api/crc-pdf-generator/v2/create', {
method: 'POST',
headers: {
// do not forget the content type header!
'Content-Type': 'application/json',
},
body: JSON.stringify({
"payload": [
{
"manifestLocation": "/apps/landing/fed-mods.json",
"scope": "landing",
"module": "./PdfEntry"
},
{
"manifestLocation": "/apps/landing/fed-mods.json",
"scope": "landing",
"module": "./PdfEntry"
}
]
}),
})
.then(async (response) => {
const res = await response.json();
console.log(res.statusID);
});
Grab the statusID from the response and add it to the status call
fetch('/api/crc-pdf-generator/v2/status/19f76eab-e3c0-482e-8a66-f02fcb28057f', {
headers: {
// do not forget the content type header!
'Content-Type': 'application/json',
}
})
.then(async (response) => {
const res = await response.json();
console.log(res);
})
Download the PDF
fetch('/api/crc-pdf-generator/v2/download/19f76eab-e3c0-482e-8a66-f02fcb28057f', {
headers: {
// do not forget the content type header!
'Content-Type': 'application/json',
}
})
.then(async (response) => {
if (response.ok === false) {
const res = await response.json()
console.log(`PDF failed to generate: ${res.error.description}`)
throw new Error(`PDF failed to generate: ${res.error.description}`)
}
return response.blob()
})
.then((blob) => {
const url = window.URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
// give name to the PDF file
a.download = 'filename.pdf';
document.body.appendChild(a); // we need to append the element to the dom -> otherwise it will not work in firefox
a.click();
a.remove(); //remove the element
});
The PDF file will be downloaded in the browser.
