When loading middleware configured in "middleware.json", loopback-boot
used to require() the full path to middleware's module main file,
for example "node_modules/strong-express-metrics/index.js".
This is breaking strong-agent probes, as it's difficult to detect
when the intercepted module (e.g. "strong-express-metrics") was loaded.
This commit modifies the compiler to omit the tail (the path to the
module main source file) when requiring middleware.
Because tryResolveAppPath returns undefined when it can’t resolve a
path the debug output for directories that cannot be resolved is fairly
useless.
You get output like this:
loopback👢compiler Skipping unknown module source dir undefined
+0ms
When you want output like this:
loopback👢compiler Skipping unknown module source dir "./models"
+0ms
Port can't be number checked to support iisnode. Using a parseInt()
or number isNumber function won't work if we want to support iisnode
which uses named pipes for ports (ex. \\.\pipe\mypipe)
Extend the options argument of boot/compile to allow the developer
to supply custom model definitions (to replace the result of
findModelDefinitions). Together with the existing options.models,
it allows to specify all model-related data and still use the benefits
which loopback-boot provides (most notably loading models in order
defined by inheritance, i.e. base models are loaded before models that
are extending them).
Use the global `isFinite` function to find the first valid port
number. This is the same behaviour as `_.isFinite` in lodash@2.x.
As a result, only values that are a valid number are accepted, e.g.
"0" is accepted but "0xy" is not.
Update to the latest version of "lodash" to use the string functions
included and drop the usage of "underscore.string".
Existing tests run checks for `flying-car` definitions to be named
`FlyingCar` so there doesn’t seem to be a need to add more checks.
`isFinite` changed from the older version of lodash to no longer coerce
strings into numbers, this commit adds a call of `parseInt` before
checking whether the value is a finite number.
`parseInt` on an undefined returns NaN which isFinite does not identify
as a number.
While changing this part, the code was reworked to use `Number.isFinite`
and thus the executor no longer depends on lodash. This should reduce
the size of the browser bundle.
This prevents an occurence where an error is completely swallowed if a script
required by loopback-boot has a bad require() call. The script is never ran
but execution continues.
Use `util.format` to build the error message, `Error` constructors
does not support placeholders like `%s`.
Detect pre-release versions and handle them in the same way as regular
releases.
Load configuration of components from `component-config`
and configure all components as specified.
Sample JSON:
{
"loopback-component-foobar": {
"option1": "value1",
"option2": "value2"
}
}
The component is expected to export the following function:
module.exports = function(app, options) { /* ... */ };
Remove duplicated entries in the array of boot scripts to run.
Because the bootDirs defaults to process.cwd(), if the user manually
includes scripts in the same directory, without specifying a bootDir,
those scripts will be included multiple times.
Introduce a convention for specifying relative paths in middleware
params: values prefixed with `$!` and starting with `./` or `../`
are resolved relatively to `middleware.json`.
Example:
{
"files": {
"loopback#static": {
"params": "$!../client"
},
"loopback#static": {
"params": "$!./public"
}
}
}
When the middleware name (path) is in the format {module}#{filename},
loopback-boot resolves the path by trying multiple locations and
using the first one that exists:
- {module} and check the {filename} property of the exports
-> e.g. loopback.rest
- {module}/server/middleware/{filename}
-> e.g. loopback/server/middleware/rest
- {module}/middleware/{filename}
-> e.g. loopback/middleware/rest
Values in any other format will bypass this resolution algorithm and
they will be used in the original form:
- a full path in a module: loopback/server/middleware/rest
- a relative path: ./middleware/custom, ./custom, ../logger
- an absolute path: /usr/local/lib/node_modules/compression
Sample JSON:
{
"routes:before": {
"morgan": {
"params": ["dev"]
}
},
"routes": {
"loopback/server/middleware/rest": {
}
},
"subapps": {
"./adminer": {
},
}
}
The JSON file can be customized using the usual conventions:
- middleware.local.{js|json}
- middleware.{env}.{js|json}
It is also possible to mount the same middleware in the same phase
multiple times with different configuration.
Example config:
{
"auth": {
"oauth2": [
{
"params": "first"
},
{
"params": "second"
}
]
},
});
