How to show message during initial loading of gwt application? -

i want display message (please wait...) or animated gif before initial entire loading of gwt application. can give me full example please. thanks because gwt app not yet loaded, have in pure html/css and/or js in html host page. easiest put in <body> , when gwt app loads starts cleaning "loading" message (e.g. document.get().getelementbyid("loading").removefromparent() ) another possibility use code-splitting : make first fragment that's small possible , display "loading" message, , load rest of app in background. in runasynccallback , hide "loading" message. that said, if feel need display such "loading" message, imo have bigger problem finding how display (and if struggle find how display one, you're in bad shape build app people enjoy using; fortunately, fixable: keep learning!).

javascript - Throw error if config object doesn't contain all required properties -

i have es6 class require config object. if property missing, i'd throw error. the solution if found keep code short , not add if(!object.propn)... every property : class myclass { constructor(config) { if (!config) { throw new error("you must provide config object"); } this.prop1 = config.prop1; this.prop2 = config.prop2; this.prop3 = config.prop3; this.prop4 = config.prop4; (const key in this) { if (!this[key]) { throw new error(`config object miss property ${key}`); } } } } is ok in javascript ? for configs, use feature destructuring assignment check whether properties in object or not using sugar of es6 (es2015). and furthermore, can set default values configs feature. {prop1, prop2, prop3: path='', prop4='helloworld', ...others} = config after destructuring assignment has been done, need check before going specific config. i.e. if (!prop1) { throw new error...

amazon web services - Can I trigger tasks to run straight after an EC2 instance has been created? -

i interested in running set of tasks after new ec2 instance has been created. @ moment doing running bash shell script via ec2's user-data option. however want move away using user-data (or @ least reduce size of shell script as possible), , instead run shell script on existing ec2 instance (which happens ansible server). does know if possible? maybe using aws service e.g. cloudwatch, sns, sqs, lambda,...etc. e.g. can cloudwatch issue message sns newly built ec2 instance reaches healthy state? there many ways solve problem. options have used in past include: creating upstart scripts on ec2 instance , creating new ami these inplace. launch future instances using ami (simple inflexible ami creation slow). do programmatic using eg. boto query aws , find out when newly launched boxes available using eg. paramiko ssh in , issue commands (much more flexible more effort). hope helps.
