Automatically compile TypeScript files on file save

I’m looking to move a vanilla node.js project to TypeScript and I’m curious about how to restart my server with the latest changes without needing to run tsc from the command line each time I make a change.

I see from this answer two options: ts-node and tsc —watch

Can someone provide a little color on the difference between these two options? I understand they accomplish the same goal, but how are they different and in which situation should I use one over the other?

"name_for_your_script" : "tsc --outFile -w", 

to your package.json file in scripts part and type this code

npm run name_for_your_script 

into your terminal. this will automatically compile your ts codes when you save it

Automatically compile TypeScript files on file save, You can add this script. «name_for_your_script» : «tsc —outFile -w», to your package.json file in scripts part and type this code. npm run name_for_your_script. into your terminal. this will automatically compile your ts codes when you save it.

TypeScript «Compile on save» feature not working in Visual Studio 2015

The «Compile on save» feature isn’t working for me after upgrading to Visual Studio 2015. When I make a change to a .ts file in my project and save, the status bar at the bottom of the IDE says Output(s) generated successfully , but the generated .js file doesn’t change.

checking and unchecking the «Automatically compile typescript files which are not part of a project» option in Tools -> Options -> TypeScript -> Project :

double checking to make sure «Compile on save» is checked in my project’s TypeScript Build properties:

As a side note, the TypeScript compilation step does work as expected when triggered by a regular build.

For me it was this option in tsconfig.json :

"compileOnSave": true, "compilerOptions": < . >, 

Restart Visual Studio for this change to take effect.

I stumbled upon this problem today: I fixed that by using the new «watch»:true compiler option, also available through JSON in most recent TypeScript versions:

After doing that, I had to solve another issue related to the following error that appeared in the output window:

Object doesn't support property or method 'watchFile' 

It turned out that my system was using an outdated version of TypeScript (1.0.x), despite I was sure I had a newer one that came with the Visual Studio 2015 Update 1 (1.7). If you run into this problem, you can easily check your tsc version by typing tsc -v from a command-prompt.

C:\Program Files (x86)\Microsoft SDKs\TypeScript 

If not, update accordingly. Open CPanel > System > Advanced > Environment Variables , select System Variables and click on Edit ; browse through the list looking for any reference to the TypeScript folder, change one of them to make it point to your TypeScript most recent installed version ( 1.7 or above) and delete any other dupes. See also screenshot below:

For additional details, read this post on my blog.

For me, and I am quite sure this is also the case for others, this was due to a mistake in the tsconfig.json.

You need to add «compileOnSave»: true. But in the global section not inside compilerOptions.

Wrong: < "compilerOptions": < "noImplicitAny": false, "noEmitOnError": true, "removeComments": false, "sourceMap": true, "target": "es5", "compileOnSave": true >, "exclude": [ "node_modules", "wwwroot" ] > Correct: < "compilerOptions": < "noImplicitAny": false, "noEmitOnError": true, "removeComments": false, "sourceMap": true, "target": "es5" >, "compileOnSave": true, "exclude": [ "node_modules", "wwwroot" ] > 

This issue seems to have been resolved with the most recent update to the TypeScript Language Services extension.

TypeScript Compile on Save in Visual Studio Code

We learned how to create the Hello World Example program in the last tutorial. Every time we make a change in the code, we need to run the tsc HelloWorld.ts to compile it to the Javascript. We can instruct the visual studio code to automatically compile the Typescript file to Javascript file whenever we make changes and save the Source file.

Open the Command prompt and create the GettingStarted Folder and then cd into it. Run code . to open the Visual Studio Code

Create a file HelloWorld.ts and the following code

To compile the above code, you need to run the

Now, If you change anything in the above code, you need to run the tsc to generate the Javascript file.

Typescript configuration file

To Enable Compile on save feature, we first need to create the Typescript Configuration file tsconfig.json .

The tsconfig.json is the file where TypeScript Compiler looks for project configuration and compiler options.

The easiest way to create the tsconfig.json file is to use the following command

This will create tsconfig.json . You can look at the generated file. It has listed all the possible compiler option, with almost all of them commented out.

Another way is to just to create the tsconfig.json and copy the following content.

Compile on Save

Once you created the tsconfig.json , You can enable compile on save feature. There are two ways you can achieve this result

Running the tsc in watch mode

Open the command prompt and cd into the project folder or Click on View -> Terminal in the VS Code Menu. In the command prompt run the following command

This will watch the folder for changes made to our typescript file and immediate run the compiler.

Using the Build Task

The second option is to hit the (Ctrl+Shift+B) from the VS Code. This will open the Execute Run Build Task window

Select tsc: watch . This will make the TypeScript compiler to watch for changes made to the TypeScript file and run the compiler on each change

Summary

In this tutorial, we learned how to enable compile on save by running tsc on watch mode.

Fixing TypeScript «Compile on Save» feature in Visual Studio 2015 ASP.NET 5 RC1

One day I’ll write an extensive post about TypeScript, the amazing JS superset developed by Microsoft in 2012 and now widely adopted by a bunch of good projects such as Angular 2, ngrx/store and SearchKit. If you stumbled upon this post you’re probably already using it and you’re fully aware of how it works. To put it in short terms:

• You write your source code using TypeScript proprietary syntax.
• Your code is compiled into plain JavaScript by a dedicated compiler (tsc) upon a trigger.
• The trigger is raised upon each build or upon a file change, depending on your Visual Studio general and/or project-specific settings.

Needless to say, setting the compile trigger upon file change is something that will greatly benefit your development speed. In order to activate it, you basically have two options: modifying the Visual Studio general settings for non-project files, or alter your project-specific settings.

General Settings

To modify the general settings, go through Tools > Options > Text Editor > TypeScript > Project and, under the Compile on Save section, check the Automatically compile TypeScript files which are not part of a project option (see the screenshot below for details).

As the option says, this method won’t work for project-specific files. In order to change the TypeScript Compiler behavior for project-related TS files you need to read the next paragraph.

Project-Specific Settings

If the TS file is included in a project, you can modify the compiler’s behavior by opening the Project Properties and going to the TypeScript Build tab. From there, check the Compile on save option to the right as shown in the screenshot below:

By looking at the .csproj file underlying code we can see that the Compile on save switch translates into the following XML node inside the Project root element:

ASP.NET 5 RC1 and above

All of the above was valid up to ASP.NET 5 beta8, where the Project Properties window was just like the one depicted above. Unfortunately, starting from ASP.NET 5 RC1, Microsoft seem to have ditched that convenient visual approach in favor of a platform-independent, script-based configuration method completely relying upon the tsconfig . json file: for those who don’t know, this is the TypeScript json-based configuration file which is in charge of defining all the TypeScript compiler options. Starting on TypeScript 1.5, that file also supports the «watch» option that can be used to keep track of file changes and, if set to true, trigger the compilation upon them.

If your project don’t have a tsconfig . json file already, you can add one: from the Solution Explorer , right-click to the project root node, then select Add > New Item : from the modal window that will appear, switch to the Client-Side tab to the left, then find the TypeScript JSON Configuration File entry and click the Add button to the lower right.

Here’s an example of how the tsconfig . json file will look like after adding the watch option:
