Div button download file context

Also I have some graphs too.. What should I do to get those? Using the above code we can able to create a pdf only one time. But for the second time it is not working. To make it work, check this answer by kristof-feys, We need to declare the doc variable inside the click function.

It preserves all the styling but it does have some limitations creates the PDF as an image so it's not searchable; seems to also be slightly blurry.

Worked very fine to me. The only problem was that some of my SVG icons were not rendered! Owe you a few beers for this. Abhishek Kamal 4 4 silver badges 15 15 bronze badges. DevZer0 DevZer0 What did u mean by "has a htmltopdf facility"?? You would need a slightly different url so you can differentiate between the two content — DevZer0. Can you give an example?? You'll be screwed if the CSS is linked though because your back-end program won't know where to find the styles unless it can grab the CSS file and apply the styles from within the file.

TypeScript Type allows you to define what a variable or function should expect as a value in order to help the compiler catch errors before runtime. As you can see, the interface ITodo defines the shape of a to-do object. Next, we have the type ContextType that expects an array of to-dos and the methods to add or update a to-do. React Context allows you to share and manage state across your components without passing down props. The context will provide the data to just the components that need to consume it.

Here, we start by creating a new context and set its type to match ContextType or null. The latter is using here to initialize the context with a null value. Next, we create the component TodoProvider that provides the context to the component consumers.

Here, I initialize the state with some data to have todos to work. The function saveTodo will create a new to-do based on the interface ITodo and then append the object to the array of to-dos. The next function, updateTodo , will look for the id of the to-do passed as a parameter in the array of to-dos and then update it.

With this, we are now able to consume the context. Here, we have a form component that allows handling data entered by the user using the useState hook. Once we get the form data, we use the function saveTodo pulled from the context object to add a new to-do. Note that I use typecasting on the useContext hook to avoid TypeScript throwing errors because the context will be null at the beginning. As you can see here, we have a presentational component that shows a single to-do.

It receives the to-do object and the function to update it as parameters that need to match the Props type defined above. This component shows the list of to-dos when the page loads.

It pulls the todos and the function updateTodo from the to-do context. That's all you need to do, you are now ready to use it in your app! It's recommended but not required to also use the styled-components Babel plugin if you can. It offers many benefits like more legible class names, server-side rendering compatibility, smaller bundles, and more. There should be a normal version and a big and primary version for the important buttons.

This is what it should look like when rendered: this is a live example, click on them! First, let's import styled-components and create a styled. This Button variable here is now a React component that you can use like any other React component!
