The Push to Ban Ransom Payments Is Gaining Momentum
Ransomware costs victims an estimated $30 billion per year and has gotten so out of control that global support for banning payments is gaining momentum.
koa-send
Advanced tools
Readme
Static file serving middleware.
$ npm install koa-send
maxage
Browser cache max-age in milliseconds. (defaults to 0
)hidden
Allow transfer of hidden files. (defaults to false
)root
Root directory to restrict file accessgzip
Try to serve the gzipped version of a file automatically when gzip
is supported by a client and if the requested file with .gz
extension exists. defaults to true.format
If not false
(defaults to true
), format the path to serve static file servers and not require a trailing slash for directories, so that you can do both /directory
and /directory/
setHeaders
Function to set custom headers on response.extensions
Try to match extensions from passed array to search for file when no extension is sufficed in URL. First found is served. (defaults to false
)Note that root
is required, defaults to ''
and will be resolved,
removing the leading /
to make the path relative and this
path must not contain "..", protecting developers from
concatenating user input. If you plan on serving files based on
user input supply a root
directory from which to serve from.
For example to serve files from ./public
:
app.use(async (ctx) => {
await send(ctx, ctx.path, { root: __dirname + '/public' });
})
To serve developer specified files:
app.use(async (ctx) => {
await send(ctx, 'path/to/my.js');
})
The function is called as fn(res, path, stats)
, where the arguments are:
res
: the response objectpath
: the resolved file path that is being sentstats
: the stats object of the file that is being sent.You should only use the setHeaders
option when you wish to edit the Cache-Control
or Last-Modified
headers, because doing it before is useless (it's overwritten by send
), and doing it after is too late because the headers are already sent.
If you want to edit any other header, simply set them before calling send
.
const send = require('koa-send');
const Koa = require('koa');
const app = new Koa();
// $ GET /package.json
// $ GET /
app.use(async (ctx) => {
if ('/' == ctx.path) return ctx.body = 'Try GET /package.json';
await send(ctx, ctx.path);
})
app.listen(3000);
console.log('listening on port 3000');
