Actually it does the download but it says the Failed - No file. pdf" — Nemer. it is in my components folder which my main. js file is too. so what I have is ". pdf" — Daniel Isaac Chavez. DanielIsaacChavez if it is downloading, but shows an error like "Failed to load PDF document" when trying to open the pdf, it may be that you are using a relative path on your href and the final path it generates does not match the one were you have stored your file. Try using an absolute path on href. Well, chances are if you've got web-pack it's going to try and minify it.
someone please pinpoint what webpack would do with an asset file in components folder , and so I don't think it's what you'd want. So, I suggest to place the asset into the public folder, under a resource or an asset name. Webpack doesn't touch the public folder and index. html and your resources get copied over in production build as is, where you may refer them as shown in next step. Refer to the file in your project Sample code: import FileSaver from 'file-saver'; FileSaver.
There are several posts around this topic, but none of them quite seem to solve my problem. I have tried using several different libraries, even combinations of libraries, in order to get the desired results. I have had no luck so far but feel very close to the solution. Essentially, I want to download a CSV file on the click of a button. I am using Material-UI components for the button and would like to keep the functionality as closely tied to React as possible, only using vanilla JS if absolutely necessary. To provide a little more context about the specific problem, I have a list of surveys. Each survey has a set number of questions and each question has answers. Once different users have answered the surveys, the admin of the website should be able to click a button that downloads a report. This report is a CSV file with headers that pertain to each question and corresponding numbers which show how many people selected each answer.
The page the download CSV button s are displayed on is a list. The list shows the titles and information about each survey. As such, each survey in the row has its own download button. Each survey has a unique id associated with it. This id is used to make a fetch to the backend service and pull in the relevant data for that survey only , which is then converted to the appropriate CSV format. Since the list may have hundreds of surveys in it, the data should only be fetched with each individual click on the corresponding survey's button. I have attempted using several libraries, such as CSVLink and json2csv. My first attempt was using CSVLink. Essentially, the CSVLink was hidden and embedded inside of the button. On click of the button, it triggered a fetch, which pulled in the necessary data. The state of the component was then updated and the CSV file downloaded.
The problem I kept facing is that the state would not update properly until the second click of the button. Even worse, when this. data was being passed into CSVLink as a prop, it was always an empty array. No data was showing up in the downloaded CSV. Eventually, it seemed like this may not be the best approach. I did not like the idea of having a hidden component for each button anyway. I have been trying to make it work by using the CSVDownload component. The DownloadReport component renders the Material-UI button and handles the event. When the button is clicked, it propagates the event several levels up to a stateful component and changes the state of allowDownload. This in turn triggers the rendering of a CSVDownload component, which makes a fetch to get the specified survey data and results in the CSV being downloaded. A problem here is that the file name of the CSV cannot be specified.
It also does not seem to reliably download the file each time. In fact, it only seems to do it on the first click. It does not seem to be pulling in the data either. I have considered taking an approach using the json2csv and js-file-download packages, but I was hoping to avoid using vanilla JS and stick to React only. Is that an okay thing to be concerned about? It also seems like one of these two approaches should work. Has anyone tackled a problem like this before and have a clear suggestion on the best way to solve it? There's a great answer to how to do this here on the react-csv issues thread. Our code base is written in the "modern" style with hooks. Here's how we adapted that example:. Have a standard onClick callback function on your button that prepares the json data you want to export to csv.
I have noticed that this question has been getting many hits over the past several months. In case others are still looking for answers, here is the solution which worked for me. A similar solution was posted here , albeit not entirely the same. It is worth reading. I would also recommend reading the documentation for refs in React. Refs are great for solving a variety of problems but should only be used when they have to be. Concerning this solution here a little modified code below worked for me. It will fetch the data on click and download the file at first time itself.
In case, the button downloads an empty CSV file and on the second click it downloads the data from the previous fetch, put your this. click inside of the setTimeout statement like so:.

Thank you! the important thing here is that we use. then to capture the table response data, update the state, and then once we exit that operation we're going to click on the csv download link using the ref await api. log e csvLink. generateCsv data ; and presto! A ref pointing back to the link was required in order for the data to be returned correctly.
