海外TECH	DEV Community	How To Read Uploaded File Content In JavaScript	https://dev.to/ideradevtools/how-to-read-uploaded-file-content-in-javascript-4of7	How To Read Uploaded File Content In JavaScriptWeb developers have many reasons to read uploaded file content in JavaScript Instead of uploading them straight to the client they can write and manipulate the file data from a local directory Compatibility issues on the JavaScript file uploader are easier to resolve before any data gets transported across the server To illustrate this let s observe the File Reader object which treats the content as a data URL function readImage file Check if the file is an image if file type amp amp file type startsWith image console log File is not an image file type file return const reader new FileReader reader addEventListener load event gt img src event target result reader readAsDataURL file Whenever a user selects a file they act on an HTML input controlled by a change event The file is then converted to a full sized img element Reading a file is an important operation because some programs have to perform algorithm training compile report findings or store large sets of data The JavaScript file uploader enables asynchronous file reading through the browser either via the promise API or the “select file attribute As such the final output of a file read is always conducted on the server side since it won t be visible in the browser unless you print out each line of the console How Do You Interact With Uploaded Text Files On A JS Framework Oftentimes the File Reader API permits a web application to save a file reference even when the user is offline In this section we will focus on the event handler FileReader readAsArrayBuffer while it returns an ArrayBuffer version of the local file Conversely the FileReader readAsText method returns the content as a text string to improve its legibility var myFile document getElementById myFile var fileOutput document getElementById fileOutput myFile addEventListener change function var fileReader new FileReader fileReader onload function fileOutput textContent fileReader result fileReader readAsText this files Use the select file HTML to initialize an input form that records the file name Next get a reference of your input file by passing in its id Now add an event listener to detect the chosen file In the line after we can call the readAsText method on the first file in the list Inside the change event define a file reader object For the load function set the output equal to the result of your file And finally confirm that the file reader is not selecting multiple files Furthermore you can read a text file by importing the React component and define an app class that extends it to retrieve all the available properties Create a constructor instance with the props argument which is called during the mounting process Is It Possible To Interpret A React File Upload To fetch the file data use the Async library to launch the File Reader API from React Assign a new FileReader object to a variable then use an onload function to grab the file information from an array of selected files or e target files in this case It should then be passed into a readAsText method Check that it is rendered properly by printing the resulting text in your console Notice how each file relies on a FormData object to load its raw data in the app The following code summarizes the steps involved in a React js file upload Event target files import React Component from react class App extends Component constructor props super props showFile async e gt e preventDefault const reader new FileReader reader onload async e gt const text e target result console log text alert text reader readAsText e target files render gt return lt div gt lt input type file onChange e gt this showFile e gt lt div gt export default App However if you re aiming for a PHP solution you should consult this article on installing the PHP file uploader It provides a thorough introduction to the PHP SDK a CMS API engineered to transform files and serve them on a private cloud where they can be tagged and securely modified One neat feature is uploading files in chunks of any size thus stabilizing the server without impacting the network latency In similar terms if you re tackling a CSV Python file upload this article from Filestack will guide you on what to do with the file path as well as how to display the imported data in Python All you really need is the file name and extension followed by the pandas module for calling the read csv location method That said sorting the data by rows or columns is entirely optional How Does Filestack s Document Viewer Compare To A JavaScript File Uploader The Document Viewer delivers a file preview in the user s browser using the Filestack processing engine and the custom solution outlined on Mozilla s PDF js So far it supports file types from PDF to DOCx and jpg to even plain text leveraging a CDN to carry out file uploads by accessing a cached copy of their URLs The preview handle of the file URL allows PDF content to be embedded in a webpage The JavaScript client will generate an iframe element inheriting the document preview in read only mode Additionally developers intending to preview files in the browser can do so in slide view The slider API responds to an array of handles containing parameters to change the theme or conversion engine Overall Filestack goes above and beyond by ensuring reliable uploads transformations and deliveries serving as an API and CDN hybrid For delivery of larger files you ll get to experience a fully optimized product that comes with instant viewing on almost any device Set up an account now

海外TECH	DEV Community	The Pros and Cons of AWS Lambda Function URLs	https://dev.to/bentorvo/the-pros-and-cons-of-aws-lambda-function-urls-524d	The Pros and Cons of AWS Lambda Function URLsAWS Lambda Function URLs were released on the th of April as an infrastructure configuration that gives you public URLs to directly trigger AWS Lambda Functions This service provides a faster and simpler way to trigger AWS Lambda Functions than AWS API Gateway or AWS Application Load Balancer ALB The URLs follow a standard structure as follows https lt url id gt lambda url lt region gt on aws Pro Fast Implementation amp DeploymentAWS Lambda Function URLs are very quick to configure and deploy whilst requiring less set up than the other alternatives When I set up the endpoint it is almost instantly available for use and only really requires a few configuration values AWS API Gateway takes longer to deploy and requires a more complex set of resources to set up The API Resources Methods Deployment Stage and Lambda Permissions are all part of setting this up AWS ALB requires additional underlying resources to be configured and has an upfront cost to using it There is quite a bit that goes into designing AWS networks but at a minimum they contain a VPC Subnets IGW and Security Groups AWS ALBs also require multiple different resources to make up a working system Pro IAM for Access ControlThe options for AWS Lambda Function URLs authentication are None or using IAM When you use None any additional security should be within the code However when you use IAM you can reference IAM resources with significant granularity This means that if you and your customers both use AWS there is a strong and simple integration point for security by just referring to their AWS IAM resources directly Pro AWS Lambda Alias SupportAWS Lambda Aliases are also supported by the new URLs which means that you can keep a consistent public facing URL when replacing the underlying infrastructure This isn t as practical as if it was done with DNS but can work if you don t mind the AWS Lambda alias and versioning system Con No Custom DNS SupportAs mentioned previously DNS can t be used for AWS Lambda Function URLs which can be an issue for both releases and the presentation of the service to customers The lack of custom DNS is similar to the Private AWS API Gateway and can cause issues if you use DNS automation for release processes It is possible to work around the custom DNS issue by deploying AWS CloudFront and pointing at the URL on the backend This is about the same effort as deploying AWS API Gateway which negates the benefits of using the new feature Con AWS Account ID ExposureAccording to AWS the new URLs expose the AWS Account ID used for the service which can provide information to any malicious actors AWS Account IDs are not considered a credential for security purposes but publishing this information should probably be avoided where possible Con Limited Network ControlsDue to the implementation of AWS Lambda Function URLs there is no way to implement network controls based on IP or any lower level than the prior mentioned authorisation This is a limitation that could be an issue depending on your environment For large enterprises like I have worked for in the past it is not acceptable but if you are running a start up it may be worth sacrificing for the speed to implementation SummaryIt is always good to see more functionality being added to AWS Lambda and serverless solutions However the new AWS Lambda Function URLs leave a lot to be desired in their access controls and DNS implementation Hopefully we will get custom DNS as a feature in the near future so that we don t have to use AWS Aliases and the AWS provided URLs More InformationLambda function URLsFollow me here for more content or contact me on Twitter BenTorvo Email ben torvo com au Website torvo com au	2022-06-30 04:17:04
