javascript - What's the right approach to saving and loading files on client-only web apps? -


i'm developing application allow user create his/her own data, , since don't have backend or database, lives on user's session.

my ideal solution following:

  1. user works application, clicks on "save", gets download prompt, downloads file his/her filesystem
  2. user clicks on "load", file input dialog gets shown, user picks his/her file, , data again on app.

i thought in using filesystem api, work on sandboxed environment defeats ability user work data in browser.

i know can simulate download stringifying data dropping window make download. however, when want load data again using input type=file, don't have ability read actual contents of file, it's one-way path.

some other apps displays contents of file user , make user copy/paste content, simplify user.

finally, support @ least latest version of desktop browsers.

what option suitable situation?

you should offer files download, read them <input type="file"> using filereader.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
