How to update typings files

Typing files enable the easy usage of JavaScript files in TypeScript projects. For Azure Data Studio, the typings files are located at /src/typings. If you add a new npm dependency or update an existing one, you may need to update the typings files in order to enable proper compilation and intellisense.

Steps:

• Add the dependency to the /package.json and /shrinkwrap.json files.
• Install the dependency:
  • Windows: scripts\npm.bat install or npm install <new dependency>
  • Mac/Linux: scripts/npm.sh install or npm install <new dependency>
• Navigate to the /src/ directory
• Run typings install --save <location to new dependency root .d.ts file>. Add the --global flag if typings says that the package must be installed as a global

For example, if I want to add @angular/core at version ~2.1.2 and I am using Windows, I can:

• Add "@angular/core": "~2.1.2" to /project.json under dependencies
• Add the following to /shrinkwrap.json under dependencies (ideally done via npm shrinkwrap):

    "@angular/core": {
      "version": "2.1.2",
      "from": "@angular/core@>=2.1.0 <2.2.0",
      "resolved": "https://registry.npmjs.org/@angular/core/-/core-2.1.2.tgz"
    }

• npm install @angular/core
• cd src
• typings install --save npm:@angular/core/index.d.ts
