示例1: getSettings
export function getSettings():Isettings{
//Give some default values
let settings:Isettings = {
port : getRandomPort()
};
// *******************************************
// Checks that iisexpress.json exist
// *******************************************
let settingsFilePath = vscode.workspace.rootPath + "\\.vscode\\iisexpress.json";
//use -> https://www.npmjs.com/package/jsonfile
var jsonfile = require('jsonfile');
try {
//Check if we can find the file path (get stat info on it)
let fileCheck = fs.statSync(settingsFilePath);
//read file .vscode\iisexpress.json and overwrite port property from iisexpress.json
settings = jsonfile.readFileSync(settingsFilePath);
}
catch (err) {
//file didn't exist so
//create .vscode\iisexpress.json and append settings object
jsonfile.writeFile(settingsFilePath, settings, {spaces: 2}, function (err) {
console.error(err);
});
}
//Return an object back from verifications
return settings;
}示例2: function
ipcMain.on("save", (event, arg) => {
if (arg.pathToSave) {
jsonfile.writeFile(arg.pathToSave, arg.spec, function(err) {
if (!err) {
event.sender.send("onSaveSuccess", {
name: arg.name,
path: arg.pathToSave

}
});
} else {
dialog.showSaveDialog(

});示例3: writetoJSON
function writetoJSON(encryptedUsername, encryptedPassword) {
console.log("encrypted username is: " + encryptedUsername);
var file = 'data.json';
var obj = {'username': encryptedUsername.toString(), 'password': encryptedPassword.toString()};
jsonfile.writeFile(file, obj, function (err) {
if (err) throw err;
console.log('username and password succesfullt saved');
})
}示例4:

// $ExpectType any
obj;
});

// $ExpectType any
obj;
});
// $ExpectType any
jsonfile.readFileSync(file);

// $ExpectType void
jsonfile.writeFile(file, obj, err => {
// $ExpectType ErrnoException
err;
});
// $ExpectType void
jsonfile.writeFile(file, obj, { spaces: 2 }, err => {
// $ExpectType ErrnoException
err;
});
// $ExpectType void
jsonfile.writeFile(file, obj, { spaces: 2, EOL: '\r\n' }, err => {
// $ExpectType ErrnoException
err;
});
// $ExpectType void示例5:
// Following are lifted from the samples on the NPM page, modified to pass
// the linter
import * as jsonfile from 'jsonfile';
