Mime database interface.
Lead Maintainer - Adam Bretz
Mimos is a convenience class for retrieving mime information objects.
new Mimos([options])
Creates a new Mimos object where:
[options]
- an option object the following keys
[override]
- an object hash that is merged into the built in mime information specified here. Each key value pair represents a single mime object. Each override value should follow this schema:
key
- the key is the lower-cased correct mime-type. (Ex. "application/javascript").value
- the value should an object following the specifications outlined here. Additional values include:
type
- specify the type
value of result objects, defaults to key
. See the example below for more clarification.predicate
- method with signature function(mime)
when this mime type is found in the database, this function will run. This allows you make customizations to mime
based on developer criteria.mimos.path(path)
Returns mime object where:
path
path to file including the file extension. Uses the extension
values of the mime objects for lookup.const mimos = new Mimos();
const mime = mimos.path('/static/public/app.js');
// mime
/*
{
source: 'iana',
charset: 'UTF-8',
compressible: true,
extensions: [ 'js' ],
type: 'application/javascript'
}
*/
mimos.type(type)
Returns mime object where:
type
the content-type to find mime information about. Uses the type
values of the mime objects for lookup.const mimos = new Mimos();
const mime = mimos.type('text/plain');
// mime
/*
{
source: 'iana',
compressible: true,
extensions: ['txt', 'text', 'conf', 'def', 'list', 'log', 'in', 'ini'],
type: 'text/plain'
}
*/
In certain situations, it can be helpful to override the built in mime type information. The optional argument to the Mimos constructor is used to override and add mime information. Below is an example to help understand how this works.
const options = {
override: {
'node/module': {
source: 'iana',
compressible: true,
extensions: ['node', 'module', 'npm'],
type: 'node/module'
},
'application/javascript': {
source: 'iana',
charset: 'UTF-8',
compressible: true,
extensions: ['js', 'javascript'],
type: 'text/javascript'
},
'text/html': {
predicate: function(mime) {
if (someCondition) {
mime.foo = 'test';
}
else {
mime.foo = 'bar';
}
return mime;
}
}
}
}
const mimos = new Mimos(options);
console.dir(mimos.path('./node_modules/mimos.module'));
/*
{
source: 'iana',
compressible: true,
extensions: ['node', 'module', 'npm'],
type: 'node/module'
}
*/
console.dir(mimos.type('application/javascript'));
/*
Note: even though we asked for type 'application/javascript', the type value is 'text/javascript' because of the override. Always use the proper content-type for retrieval.
{
source: 'iana',
charset: 'UTF-8',
compressible: true,
extensions: ['js', 'javascript'],
type: 'text/javascript'
}
*/
console.dir(mimos.type('text/html'));
/*
someCondition is true:
{
source: 'iana',
compressible: true,
extensions: ['html','htm'],
type: 'test/html',
foo: 'test'
}
someCondition is false:
{
source: 'iana',
compressible: true,
extensions: ['html','htm'],
type: 'test/html',
foo: 'bar'
}
*/
