海外TECH	DEV Community	Setting up TailwindCSS 3.0 on a Laravel project	https://dev.to/sourcegraph/setting-up-tailwindcss-30-on-a-laravel-project-1cb8	Setting up TailwindCSS on a Laravel projectIn the first part of our series we saw how to bootstrap a new Laravel application with Sail and Docker This allows you to develop a Laravel application without having to set up a PHP development environment on your system With the base application up and running the second part of our livestreaming series was focused on setting up a basic blog layout using TailwindCSS In this post you ll see a recap with all steps executed during the live session so that you can reproduce them at your own pace PreparationBefore moving along make sure you have followed all steps in the first tutorial of the series in order to bootstrap your Laravel application and development environment This will require you to have Docker Curl and Git installed on your system If you haven t yet bring your environment up with vendor bin sail up dThis command will start up your environment and keep it running in the background Your Laravel application should now be available at http localhost Open this URL on your browser and you ll see a page like this For convenience you may want to create an alias to execute Sail from the application s root directory ln s vendor bin sail sailchmod x sailNow you can run Sail like this sail artisanThis command will run Artisan on the application container Installing and configuring TailwindCSS with LaravelStart by installing the frontend dependencies via NPM The npm command is available as a shortcut with Laravel Sail sail npm installNext install TailwindCSS with sail npm install D tailwindcss postcss autoprefixerThen run the following command to generate your Tailwind configuration file sail npx tailwindcss initNow you ll need to tell Laravel that you want to compile Tailwind resources using Laravel Mix Open the webpack mix js file located at the root of your application and include tailwindcss as a postCss plugin This is how your mix js definition should look like when you re finished webpack mix jsmix js resources js app js public js postCss resources css app css public css require tailwindcss Next you should update your tailwind config js file to include the paths to all your template resources The following example will include all blade templates and JS files in your resources folder tailwind config jsmodule exports content resources blade php resources js theme extend plugins The next step is to import all tailwindcss component layers into your application s CSS Open the resources css app css file and include the following content resources css app css tailwind base tailwind components tailwind utilities The configuration is done You can now run the command that will watch for changes in your frontend resources and build assets in real time while you develop your application sail npm run watchThis command will block your terminal You can stop it at any time with CTRL C Creating a basic blog templateNow that your setup is complete you can start building the frontend of your application For this demo we re building a basic blog template with a main column and a sidebar on the right A good idea to get started is to search for a basic HTML boilerplate code template and build from there After some experimentation we built the following template during the livestreaming session Save this content to a file named index blade php in your resources views folder resources views index blade php lt doctype html gt lt html lang en gt lt head gt lt meta charset utf gt lt meta name viewport content width device width initial scale gt lt title gt My DEV Blog lt title gt lt meta name description content My DEV Blog gt

the asset call the rest is purely HTML and CSS styled with TailwindCSS descriptive classes After saving the template open your routes web php file and update your main route definition so that it renders your new template instead of the default Laravel welcome page This is how the file should look like once you re done routes web phpRoute get function return view index Save the file If you reload your browser now you should see a page like this In a later part of this series we ll turn this skeleton into an actual dynamic template using more advanced Blade features ConclusionInstalling TailwindCSS within a Laravel project requires a few configuration steps but once you get the build command running you can greatly speed up your frontend development process by making use of the advanced features of Tailwind including just in time processing for super fast build times as well as many other features included in the newest version In the next part of this series we ll move to the backend and create an Artisan command to import posts from a DEV user profile You can follow Sourcegraph on Twitch to be notified when we go live	2021-12-15 15:31:43

海外TECH	DEV Community	Building an AWS Integration for Salesforce Image Handling	https://dev.to/salesforcedevs/building-an-aws-integration-for-salesforce-image-handling-f74	Building an AWS Integration for Salesforce Image Handling IntroductionIn this article we ll look at a solution that not only offloads your Salesforce image storage to Amazon Web Services AWS but also resizes and renders those images on demand By offloading image storage to other solutions your organization can free up Salesforce storage capacity We ll build off an example use case from Salesforce Field Service but there are many other scenarios that can take advantage of these techniques Having both a Salesforce org with Field Service installed and an AWS account are prerequisites for this article Use caseFor our example we will look at a fictional property maintenance company Acme Maintenance Acme manages property safety inspections on behalf of its clients On site inspectors use Salesforce Field Service to record their findings on their visits As part of their site visits inspectors take a lot of photographs on their mobile devices and these are saved back to Salesforce Acme would like to use these images in the Service Reports that they provide to their clients Acme has discovered that with the number of site visits multiplied by the number of images per visit and the size of those images and on top of that they want to see reasonably sized thumbnails of those images in Salesforce and surface them on Service Reports they re reaching the initial default file storage limits on Salesforce While they could easily purchase more file storage within Salesforce their Salesforce architect has suggested that off platform storage may be more optimal To solve this we will look at interfacing with AWS for both image storage and image processing resizing cropping orientation and so on AWS ServicesFor our use case we will look at one of the AWS reference architectures the Serverless Image Handler and take advantage of AWS CloudFormation to deploy it In some ways you can liken CloudFormation to Salesforce metadataーa way to deploy your resources in a declarative script based manner The AWS documentation goes into greater detail but in summary we will leverage the following components Cloudfront load balancing the requests into the APIAPI Gateway publishing the external API for useLambda the serverless application that handles the image processingS storage of the original uploaded images and log filesSecrets Manager optional If you use the image URL signature feature then you can retrieve secrets for digital signing from here Rekognition if you require content moderation smart cropping facial recognition and so on AWS configurationBy using a CloudFront template we don t need to know a great deal about each of these AWS technologies we simply have to go through a few configuration steps Please note that in this example we will take default settings rather than enable advanced features It s recommended that you read through the implementation guide Create an S bucket for your imagesThe first task is creating an S bucket to store our original image files Choose a bucket name that is unique and lowercase and then pick the region that is geographically closest to you Check the box to “Block all public access Deploying the CloudFormation stackFrom the Serverless Image Handler main page click on Launch in the AWS Console to start deploying your own instance Before you start populating fields be sure to select your AWS region in the top right corner of the screen on the CloudFormation page Select the same region as your S bucket from the previous step The path to the CloudFormation template should be pre populated Click Next On the next screen we specify a name for our stack and provide the name of our S bucket Select “No for the “Demo UI and then click Next again On the “Configure stack options page accept the default and click Next one more time Finally on the review page click the Create Stack button As you refresh the page you ll see the progress of your stack build which can take a few minutes Then you ll see this As a final step we need to go to the Output tab of the build and copy the value of the ApiEndpoint parameter as we ll be using this in our Salesforce build Salesforce build Custom Objects and fieldsIn Salesforce we ll start by creating a new custom object called Work Order Attached Image which will hold the information for any image attachments that relate to a Work Order The key fields to note are Image RTF Original Image URL and Resized Image URL When asked whether to add a related list to the Work Order page layout be sure to select it Custom metadataNext we need to create a Custom Metadata type to store our configuration settings In Setup search for Custom Metadata and create a new type called AWS Settings with the custom fields shown below Once created click the Manage AWS Settings button and add the following three settings and save them For the image handler endpoint value use the ApiEndpointvalue from AWS CloudFormation Named credentialsOur next configuration item is for securely handling the access to AWS from Salesforce In Setup search for Named Credentials and create the following two credentials substituting in your own AWS URL region and access key secret from your AWS user Be sure the Name fields are as shown in the screenshots as this is used later in the code Remote site settingsIn order for the images from AWS to appear in our Service Reports we need to add the API endpoint as a trusted domain via Remote Site Settings Triggers and classesRevisiting our scenario image attachments from Field Service populate Salesforce as ContentDocument objects and associated supporting objects Their object model looks like this In order to capture newly attached images in the model we can simply add a new Apex trigger to the ContentDocumentLink object This will allow us to reference both the attachment and the object it is attached to ContentDocumentLinkTrigger and ContentDocumentLinkTriggerHandlerWe build a ContentDocumentLinkTrigger view code on GitHub that hands off processing to an Apex class for handling the trigger Our trigger handler ContentDocumentLinkTriggerHandler view code on GitHub takes the list of new ContentDocumentLinks and collates them into a Map keyed by the linked entity ID It then inspects them to see the type of the linked entity andーif it is a Work Orderーadds them to a Set for processing This processing consists of building further collections to map an entity to associated ContentDocument records before handing this data off to a Batch Apex class for processing asynchronously WorkOrderAttachmentBatchThe batch class for Work Order attachments WorkOrderAttachmentBatch view code on GitHub iterates through the supplied collections building up new WorkOrderAttachedImage records from the image filename and base URL of the AWS S bucket A call is made to the ImageRotationHandler class to get the crafted URL with which to call the Image API Then it constructs an RTF field with some simple HTML for rendering the resulting image Once the records have been created and saved the list of image attachments passes to another batch class for the upload process ImageRotationHandlerThe ImageRotationHandler view code on GitHub is a small class that handles the construction of a valid request to the Image API handler It constructs the required JSON structure from the parameters serializes it to a string encodes it as Base and then appends this to the URL of the image handler endpoint Formatting requests is included in the AWS template documentation under the Deployment section SUploadHandlerThe final batch class SUploadHandler view code on GitHub handles the uploading of the attached images to our S bucket via a simple REST API call Service ReportsNow that we have our images on S and our custom object populated with our links to the images we can now return to our Field Service use case In our Salesforce setup search for and click on Service Report Templates For demo purposes we ll create a new template On the template page select Work Order from the Related Templates dropdown list In the Body area of the template add a new List section element based on the Work Order Attached Image object as shown below Save the template and activate it We re now ready for testing Create a new Work Order in Salesforce and save it Then upload an image file in JPG or PNG format to the Files section Once the image has been uploaded refresh the page You should then see a new record in the Work Order Attached Images related list Clicking on the record should show a record similar to this with the S image displayed From the Work Order click the Create Service Report button It may be in the overflow menu dropdown Select the Service Report template we created earlier and click the Create PDF button A preview of the Service Report PDF should render complete with a thumbnail of your uploaded image in the appropriate section ConclusionIn this article we have successfully deployed a complete image handler solution to AWS using a reference implementation from the AWS Solutions Library We have implemented code with supporting objects and configuration in Salesforce to transfer uploaded image attachments to S and surface them within the platform and on Service Reports With this architecture we have the potential to reduce storage needs for image files within Salesforce Outside of Field Service there are many other use cases for reducing image storage needs Another popular scenario for example is for Salesforce powered web experiences in which users need to submit image files Next Steps and ResourcesHere are some ideas for taking this architecture further Implementing removal of the original Salesforce files once S has themCreating a custom Lightning Web Component to display the uploaded imagesExtending this implementation to support other file types such as PDF documentsHere are some useful links related to this implementation AWS Serverless Image HandlerThe Sharp Library which provides the image processing capability we use in AWS	2021-12-15 15:07:23
