Substituting placeholders within a docx template remains incomplete

Question

Substituting placeholders within a docx template remains incomplete

Utilizing this specific library, I am implementing a feature to substitute placeholders within a docx template and generate multiple documents. The technologies involved are neutralino and vue for the front-end, where I have devised a method that transmits the chosen docx file along with the necessary data to the library for processing. To populate the placeholders, I have structured a loop in the following manner:

// assembling all required data into an array
for(let i = 0; i < this.selectedData.length; i++){
  this.dataPlaceholders.push({
   key1: val1,
   key2: val2
  })
}
//invoking the library to produce documents

for(let i; i < this.dataPlaceholders.length; i++){
 this.docxTemplate.process(template, this.dataPlaceholders[i])
}

The merged data comes from two arrays, and upon console logging them, it is evident that everything is properly arranged. Per the documentation instructions, I've utilized curly brackets {} for placeholder designation, matching each placeholder name with the keys in the dataPlaceholders array. Upon experimentation, while I managed to create distinct documents, the placeholders remained untouched resulting in empty fields within the documents.

What steps can be taken to rectify this issue and ensure proper functionality?

After experimenting and exploring various approaches on how to incorporate an asynchronous call within a loop, I have decided to utilize the Array.prototype.map function which has proven to be effective. I made adjustments to my Vue method that invokes the library by converting it into an async method. However, I refrained from making any changes to the then block so that I can retrieve the processed documents once the library completes its processing.

this.dataPlaceholders.map( async (data, index) => {
  let filename = data.supplier + '.docx'
  this.docxTemplate.process(template, data).then( (result) => {
    // download files code goes here
     let anchor = document.createElement('a')
     let downloadLink = URL.createObjectURL(result)
     anchor.href = downloadLink
     anchor.download = filename
     anchor.click()
  })
})

The only remaining task is to figure out how to revoke the blob URL once all the files have been successfully downloaded.

Instead of using the map function, I recommend utilizing a for loop. In cases where your function is asynchronous, consider implementing the following code snippet:

async function myFunc(){
    for( let i = 0; i < myArray.length; i++ ){
        await functionTocall(param1, param2)
    }
}

By employing a for loop, you ensure that each iteration will wait for the async function to return a promise, guaranteeing accurate execution within the loop.
